This document relates to passively populating participant lists of an electronic communications system and organizing the entries within the participant lists.
When a user first uses an electronic communications system, the user may be provided with a participant list to be used with the electronic communications system. The user may populate a participant list with identifiers of other users of the electronic communications system with which communication may occur through the electronic communications system. The task of manually populating the participant list may be inefficient, especially when a large number of other users are to be added to the participant list. The user also may desire to notify the other users that the user has become a new user of the electronic communications system. Manually doing so also may be burdensome when the number of other users is large.
The user may not be involved in strong relationships with all of the users or may not communicate with all of the users included in the participant list. Furthermore, as users are continually added to the participant list, the participant list may include users with which the user no longer communicates or with which the user otherwise has a relationship with a low strength. The users included in the participant list having high strength relationships with the user may be mixed with users having low strength relationships with the user, which may prevent the user from easily identifying and accessing the users corresponding to high strength relationships, especially when the number of users corresponding to high strength relationships is small relative to the size of the entire participant list.
In one general aspect, passively populating a list of participants of an electronic communications system includes maintaining a participant list of users of an electronic communications system to be used by a user of the electronic communications system. Existing users of the electronic communications system that are known to the user are identified, and communications strengths between the user and each of the identified existing users are determined. The identified existing users with the highest communications strengths are designated for addition to the participant list.
Implementations may include one or more of the following features. For example, the designated users with the highest communications strengths may be added to the participant list. A group within the participant list to which each of the designated users should be added may be identified. Identifying the group within the participant list may include creating the group within the participant list. Identifying a group within the participant list to which a designated user is to be added may include identifying a group within the participant list that includes users of the electronic communications system that share a characteristic with the designated user.
Identifying a group within the participant list to which a designated user is to be added may include identifying a group within a second participant list that includes the designated user. A group within the participant list that corresponds to the group within the second participant list may be identified as the group within the participant list to which the designated users should be added. The participant list may be a buddy list of an instant messaging system, the group within the participant list may be a category within the buddy list, the second participant list may be an address book of an e-mail system, and the group within the second participant list may be a category within the address book. Alternatively, the participant list may be an address book of an e-mail system, the group within the participant list may be a category within the address book, the second participant list may be a buddy list of an instant messaging system, and the group within the second participant list may be a category within the buddy list.
Identifying a group within the participant list to which a designated user is to be added may include identifying a group within the participant list that includes users of the electronic communications system that are associated with the designated user. Adding the designated users to the participant list may include adding each of the designated users to the corresponding identified group within the participant list. The participant list may be a buddy list of an instant messaging system, and the group within the participant list may be a category within the buddy list. Alternatively, the participant list may be an address book of an e-mail system, and the group within the participant list may be a category within the address book.
A number of users that may be added to the participant list may be determined. Adding the designated users to the participant list may include adding a number of the designated users equal to the determined number of users to be added to the participant list.
The identified existing users may be sorted based on the corresponding communications strengths prior to designating the identified existing users with the highest communications strengths for addition to the participant list. Sorting the identified existing users may include ordering the identified existing users with higher communications strengths before the identified existing users with lower communications strengths.
Identifying the existing users that are known to the user may include identifying existing users known to the user that are not included in the participant list. Identifying the existing users that are known to the user may include identifying existing users of the electronic communications system that are included in a contact list maintained by the user as being known by the user. Identifying the existing users that are known to the user may include identifying people known to the user that are associated with an identifier used in the electronic communications system as being known to the user.
Determining communications strengths between the user and each of the identified existing users may include determining degrees of separation between each of the identified existing users and the user. Designating the identified existing users with the highest communications strengths may include designating the identified existing users with the smallest numbers of degrees of separation from the user.
Determining communications strengths between the user and each of the identified existing users may include determining whether each of the identified existing users includes the user in a contact list maintained by the existing user and is included in a contact list maintained by the user. Designating the identified existing users with the highest communications strengths may include designating the identified existing users that include the user in contact lists maintained by the identified existing users and that are included in a contact list maintained by the user before designating the identified existing users that do not include the user in contact lists maintained by the identified existing users or that are not included in a contact list maintained by the user.
Determining communications strengths between the user and each of the identified existing users may include determining a number of messages sent between the user and each of the identified existing users. Designating the identified existing users with the highest communications strengths may include designating the identified existing users with the highest numbers of messages exchanged with the user.
Determining communications strengths between the user and each of the identified existing users may include determining a frequency with which messages between the user and each of the identified existing users are exchanged. Designating the identified existing users with the highest communications strengths may include designating the identified existing users that exchange messages with the user with the highest frequencies.
Determining communications strengths between the user and each of the identified existing users may include determining whether each of the identified existing users is a direct or indirect addressee of messages from the user. Designating the identified existing users with the highest communications strengths may include designating the identified existing users that are direct addressees before designating the identified existing users that are indirect addressees.
Determining communications strengths between the user and each of the identified existing users may include determining whether the user subscribes to contact information for each of the identified existing users and whether each of the identified existing users subscribes to contact information of the user. Designating the identified existing users with the highest communications strengths may include designating the identified existing users that are both subscribers to the user's contact information and publishers of contact information that is subscribed to by the user before designating the identified existing users that are not both subscribers to the user's contact information and publishers of contact information that is subscribed to by the user.
Determining communications strengths between the user and each of the identified existing users may include determining a frequency with which messages are exchanged in a chat room between the user and each of the identified existing users. Designating the identified existing users with the highest communications strengths may include designating the identified existing users that exchange messages in the chat room with the user with the highest frequencies.
Determining communications strengths between the user and each of the identified existing users may include determining amounts of time for which the user and each of the identified existing users have exchanged messages. Designating the identified existing users with the highest communications strengths may include designating the identified existing users that have exchanged messages with the user for the longest amounts of time.
Determining communications strengths between the user and each of the identified existing users may include determining amounts of contact information for the user held by each of the identified existing users and amounts of contact information for each of the identified existing users held by the user. Designating the identified existing users with the highest communications strengths may include designating the identified existing users for which the user holds the largest amounts of contact information and that hold the largest amounts of contact information for the user.
Determining communications strengths between the user and each of the identified existing users may include determining whether each of the identified existing users both sends messages to the user and receives messages from the user. Designating the identified existing users with the highest communications strengths may include designating the identified existing users that both send messages to the user and receive messages from the user.
Determining communications strengths between the user and each of the identified existing users may include determining communications strengths between each of the identified existing users and a different user. Designating the identified existing users with the highest communications strengths may include designating the identified existing users with the highest communications strengths with the different user.
The electronic communications system may be an instant messaging system, a chat system, or an e-mail system. The participant list may be a social network of the user.
In another general aspect, a graphical user interface is used to manage a list of users of an electronic communications system with which electronic messages may be exchanged. The graphical user interface includes a participant list display associated with a user of the participant list display that includes users of an electronic communications system. One or more of the users are included automatically in the participant list display as a result of being identified as being known to the user and having high communications strengths with the user.
Implementations may include one or more of the following features. For example, the participant list display may include groups that are associated with one or more of the users included in the participant list display. A group included in the participant list display may be associated with the one or more automatically included users.
The participant list display may be a display of a buddy list associated with an instant messaging system, or a display of an address book associated with an e-mail system.
In yet another general aspect, passively populating a list of participants of an electronic communications system includes maintaining a participant list of users of an electronic communications system to be used by a user of the electronic communications system. Communications strengths between the user and existing users of the electronic communications system that are known to the user are identified. The identified communications strengths are used to populate the participant list for the user.
Implementations may include one or more of the following features. For example, the electronic communications system may be an instant messaging system, a chat system, or an e-mail system. The participant list may be a buddy list of an instant messaging system, an address book of an e-mail system, or a social network of the user.
These general and specific aspects may be implemented using a system, a method, or a computer program, or any combination of systems, methods, and computer programs.
Other features will be apparent from the description and drawings, and from the claims.
Like reference symbols in the various drawings indicate like elements.
A participant list of a communications system that is used by a first user is passively populated with identifiers of other users that are known to the first user. Doing so relieves the first user from having to manually add the identifiers of the other users to the participant list. Other users that are known to the first user are identified, and a strength of the relationship between the first user and each of the known users is determined. A portion of the known users (e.g., the known users with the strongest relationships) may be added to the participant list, particularly when all of the known users may not be added to the participant list. The known users may be identified from a contact list that is used by the first user. The known users that are added to the participant list may be added to the participant list in general, or to a specific group or groups within the participant list that may be created for the addition of the known users.
A first user may exchange electronic messages with a second user, and the relationship between the first and second users with respect to the exchanging of electronic messages may be described by a communications strength between the first and second users. The communications strength between the first and second users is a numerical measure of the strength of the relationship between the first and second users with respect to exchanging electronic messages. Higher communications strengths typically correspond to stronger relationships. Communications strengths may be useful when comparing relationships while passively adding contacts to participant lists, announcing new membership to known contacts, or organizing participant lists. The communications strength between the first and second users also may be called the communications strength of the first user with respect to the second user, the communications strength of the second user with respect to the first user, or more simply the communications strength of the first or second users.
A calculation of the communications strength between the first and second users may consider the number of messages that are exchanged between the first and second users, and a higher number of messages may correspond to a higher communications strength. Similarly, the calculation may consider the frequency with which messages are exchanged between the first and second users, and a higher frequency may correspond to a higher communications strength. In implementations where the first and second users are users of a chat room, the calculation may consider the frequency with which messages are exchanged between the first and second users in the chat room, and a higher frequency of messages exchanged in the chat room may correspond to a higher communications strength.
The time over which messages are exchanged by the first and second users may affect the communications strength between the first and second users. In general, a longer amount of time over which the first and second users exchange messages may correspond to a higher communications strength. For example, the communications strength between the first and second users may be higher when the first and second users exchange a lower number of messages over a longer period of time than when the first and second users exchange a higher number of messages over a shorter period of time. Similarly, the communications strength may be higher when the first and second users exchange messages with a lower frequency for a longer period of time than when the first and second users exchange messages with a higher frequency for a shorter period of time. In general, exchanging messages over a longer period of time may indicate that the first and second users have a stronger, more enduring relationship.
A calculation of the communications strength between the first and second users may consider only messages sent between the first and second users with the electronic communications system, or all types of messages sent between the first and second users. For example, in implementations where the electronic communications system is an instant messaging system, the communications strength between the first and second users may depend on the instant messages sent between the first and second users, or the communications strength may depend on all communications between the first and second users, including, for example, instant messages, e-mail messages, and cellular telephone calls.
Alternatively or in addition to using the exchanging of electronic messages to measure communications strength between users, whether or not a first user and a second user each list each other in respective contact lists, such as address books, buddy lists, e-mail distribution lists, social networks, mobile telephone phone books, lists of members of an organization, and/or white lists, may be considered when calculating the communications strength between the first and second users. Inclusion in respective contact lists may be indicative of a strong relationship between the first and second users. As a result, a high communications strength may be assigned when the first user is listed in a contact list used by the second user and when the second user is listed in a contact list used by the first user. Each contact list may be a contact list that includes a single user's contacts, or a global contact list that includes multiple users' contacts. A lower communications strength may be assigned when only one of the first and second users lists the other user in a contact list used by the first or second user. An even lower communications strength may be assigned when neither the first nor the second user includes the other user in a respective contact list. The type of contact lists that include the first or second users may affect the communications strength. For example, a higher communications strength may be assigned when the first and second users are listed in mobile telephone phone books than when the first and second users are listed in white lists. Such a communications strength may be assigned because adding the first and second users to the mobile telephone phone books may be harder and may require more effort by the first and second users than adding the first and second users to the white lists.
The calculation of the communication strength also may consider the amount and type of contact information that the first and second users have for one another. The communications strength may be directly related to the amount of contact information that the first and second users have for one another. For example, a higher communications strength may be assigned when the first user has both work and home contact information for the second user than when the first user only has work or home contact information for the second user. As another example, a higher communications strength may be assigned when the second user has home contact information for the first user than when the second user has work contact information for the first user. Such a consideration may be particularly important when the second user typically communicates with the first user when the first user is at home.
The calculation of the communications strength also may consider the degree of separation between the first and second users. The degree of separation between the first and second users describes a relationship between the first and second user. A low degree of separation between the first and second users may indicate a close, and consequently strong, relationship. Typically, user contact lists are evaluated to determine the number of degrees (or hops) that are required to link or relate the first and second users. For example, user A may list user B in user A's address book, user B may list user C in user B's address book, and user C may list user D in user C's address book. Here, user D is linked to user A by two degrees of separation (with user B as the first degree and user C as the second degree). User A is related to user C by one degree of separation (user B) and user B is separated from user D by one degree of separation (user C). Users A and B, users B and C, and users C and D are each respectively separated by zero degrees of separation. In general, a smaller degree of separation may correspond to a higher communications strength.
Whether or not the first and second users are direct or indirect addressees of messages sent between the first and second users may be considered when calculating the communications strength between the first and second users. The first and second users being direct addressees of the messages may be indicative of a strong relationship between the first and second users. The first user may be called a direct addressee of a message from the second user when the message is received directly from the second user, and the first user may be called an indirect addressee of the message when the message is received from the second user through one or more other users. In general, the number of other users through which the message is received is inversely proportional to the communications strength between the first and second users.
Alternatively or additionally, in implementations where the messages sent between the first user and the second user are e-mail messages, whether the first and second users are listed in the “To,” “Carbon Copy,” or “Blind Carbon Copy” fields of the e-mail messages may indicate whether the first and second messages are direct or indirect addressees. For example, if the second user is listed in the “To” field of an e-mail message sent by the first user, the second user may be a direct addressee of the message. If the second user is listed in the “Carbon Copy” or “Blind Carbon Copy” fields of the e-mail message, the second user may be an indirect addressee of the message. A higher communications strength may be assigned when the first or second users are direct addressees than when the first or second users are indirect addressees. The number of times that the first and second user are direct or indirect addressees may affect the communications strength, with the communications strength being directly related to the number of times that the first and second user are direct or indirect addressees.
Similarly, whether or not the first and second users are both senders and recipients of messages sent between one another may be considered when calculating the communications strength between the first and second users. The first and second users being both senders and recipients of the messages may be indicative of a strong relationship between the first and second users. A higher communications strength may be assigned when both the first and the second users are both senders and recipients of the messages. A lower communications strength may be assigned when both the first and second users are not both senders and recipients of the messages, which may occur when the first user sends messages to the second user and does not receive messages from the second user in response, or vice versa.
The first and second users may publish personal contact information, and the first and second users may subscribe to the published contact information. More particularly, the first user may subscribe to contact information published by the second user, and the second user may subscribe to contact information published by the first user. When a user subscribes to published contact information, any changes to the published contact information are automatically propagated to the user. Subscribing to each other's contact information may be indicative of a strong relationship between the first and second users. Therefore, a high communications strength may be assigned to the relationship between the first and second users when the first and second users subscribe to each other's contact information. A lower communications strength may be assigned to the relationship when only one of the first and second users subscribes to the other user's published contact information. An even lower communications strength may be assigned when neither of the first and second users subscribes to each other's contact information.
Other characteristics of the first and second user or their communication behavior may be considered when calculating the communications strength between the first and second users. For example, a type of relationship between the first and second user may affect the communications strength between the first and second user. For example, in one implementation, a higher communications strength may be assigned if the first and second users are family members than if the first and second users are business contacts.
One or more of the above characteristics of the relationship may be included in a calculation of the communications strength between the first and second users. For each of the included characteristics, a numerical measure corresponding to the characteristics is identified. The numerical measure of a characteristic may be a raw measurement of the characteristic or some other numerical value representative of the characteristic. The communications strength may be calculated from the numerical measures of the characteristics using, for example, a weighted average or some other function of the numerical measures of the characteristics.
In some implementations, the communications strength between the first and second users may depend on the communications strength between the first user and a third user, or on the communications strength between the second user and the third user. For example, a relationship may not have been established between the first and second users, which may prevent the calculation of the communications strength between the first and second users. The relationship between the third user and the first or second user may be similar to the expected relationship between the first and second users. For example, the first user may be a new employee of a company that already employs the second and third users. The first user may be working with the second user in a similar manner as the third user, so the relationship between the second and third users may model the expected relationship between the first and second users. As a result, the communications strength between the second and third users may represent the expected communications strength between the first and second users. The communications strengths of the third user with the first or second users may be calculated as described above. The communications strength between the second and third users also may be combined with the communications strength between the first and second users that is calculated as described above. In some implementations, the communications strengths between the second user and multiple other users may be combined with the calculated communications strength between the first and second users.
In some implementations, the first user or the second user may use multiple identifiers when communicating over the electronic communications system. For example, the first user may have two identities that are both used to communicate with the second user. A separate communications strength may be calculated for each of the identifiers. The separate communications strength for a particular identifier describes the relationship between the first user and the second user when communicating with the particular identifier. The overall communications strength between the first and second user may be calculated by combining the separate communications strengths for each of the multiple identifiers. For example, a weighted average of the separate communications strengths may be used to combine the separate communications strengths into the overall communications strength between the first and second users.
The communications strength between the first and second users may be calculated in real time as the first and second users communicate. For example, each time a message is sent between the first and second users, a calculation of the communications strength may be performed. Alternatively or additionally, the communications strength may be determined after the messages have been exchanged. For example, logs of the messages sent between the first and second users, such as an e-mail log or an instant message log, may be inspected and processed to determine the communications strength. Other information indicative of the relationship between the first and second users may be processed when calculating the communications strength.

The process 100 begins by maintaining a participant list to be used by the user of the electronic communications system (105). The participant list is maintained for use by the user such that the user may use the participant list to communicate with the other users included in the participant list. The participant list includes one or more identifiers of other users of the electronic communications system, and the other users typically are the other users with whom the first user commonly communicates. The first user may select an identifier from the participant list to address a message to be sent with the electronic communications system to the corresponding user. The identifiers included in the participant list may be separated into one or more groups that categorize or otherwise organize the other users.
Other people that are known to the user are identified (110). The known people may be identified from a contact list that includes contact information for people with whom the user may communicate. People included in the contact list are inferred to be known by the user. Examples of the contact list include a buddy list of an instant messaging system, an e-mail address book of an e-mail system, an e-mail distribution list, a list of people in the user's social network, a list of people in a phone book of a mobile telephone used by the user, a list of members of an organization that includes the user, and a white list of people from whom communications are allowed. The contact list may be maintained by the user himself, or by another person or a central system on behalf of the user. For example, the user may be an employee of a company, and the contact list may be a list of e-mail addresses of all employees of the company that is maintained by the company. The user may access and use the contact list from the central system, or the user may use a copy of the contact list that is stored on a computer system used by the user. In one implementation, the set of people known to the user is filtered to include only the people known to the user that are not already included in the participant list.
The known people that are existing users of the electronic communications system are identified (115). In one implementation, identifying the known people that are existing users of the electronic communications system may include identifying identifiers of the known people in the electronic communications system. Identifying the identifiers of the known people may implicitly indicate whether each of the known people is a user of the electronic communications system. More particularly, if an identifier for one of the known people in the electronic communications system may not be identified, then it may be assumed that the known person is not an existing user of the electronic communications system. The known person may be sent an invitation to join the electronic communications system using the information in the contact list.
In some implementations, the contact list includes an indication of the identifiers of the known users in the electronic communications system, and identifying the identifiers of the known people may include identifying the identifiers from the contact list. If the contact list does not include an identifier for a known person, then it may be assumed that the known person is not a user of the electronic communications system. In other implementations where the contact list does not include the identifiers, the identifiers may be otherwise determined. For example, contact information in the contact list may be used to identify the identifiers for the known people. For instance, the participant list may be a buddy list of an instant messaging system and the contact list may include e-mail addresses of the known people that are not identifiers of the known people in the instant messaging system. However, the instant messaging system may maintain a mapping of e-mail addresses to identifiers, and the e-mail addresses may be used to identify the corresponding identifiers from the mapping. If the mapping does not include an identifier for an e-mail address of a known person, then it may be assumed that the known person is not a user of the instant messaging system. Other contact information, such as, for example, a phone number, a name, and/or an address, may be used to identify the identifiers for the known people. For example, a system may maintain a mapping of other contact information to identifiers, and the other contact information may be used to identify the corresponding identifiers from the mapping.
Communications strengths are determined for each of the known people for which an identifier in the electronics communications system has been identified (120). The communications strengths may be calculated from one or more characteristics of the relationship between the user and each of the existing users, as described above. Alternatively or additionally, the communications strengths may be indicated by the contact list from which the known people were identified. For example, the contact list may be organized such that the communications strengths of the included people are indicated by the positions of the included people within the contact lists. The existing users may be sorted based on the communications strengths that have been determined (125). Sorting the existing users by corresponding communications strength may help in determining which of the existing users are added to the participant list.
In other exemplary implementations, communications strengths may be determined between the user and the people known to the user, and the known people that are existing users of the communications system then may be identified.
A number of the existing users that may be added to the participant list may be determined (130). The participant list may have a maximum capacity, such that the participant list does not have sufficient space for all of the known people for which identifiers have been identified. In such a case, the number of existing users that may be added to the participant list is the number of remaining spaces in the participant list. Alternatively or additionally, the number of existing users that may be added may depend on the corresponding communications strengths. For example, a particular number of existing users may be determined because adding more existing users to the participant list may result in the addition of existing users with a communications strength that is lower than desired.
The known people corresponding to the highest communications strengths are identified for addition to the participant list (135). For example, a number of the known people with the highest communications strengths equal to the maximum allowable number of additions to the participant list may be identified for addition to the participant list. In implementations where a number of allowable additions is not determined, all of the existing users may be identified for addition to the participant list.
A group within the participant list to which each of the existing users is to be added may be created (140). For example, a special group may be created within the participant list for users that have been passively added to the participant list with the process 100. Alternatively or additionally, a group may be created for users in the participant list that have a certain characteristic. For example, a group may be created within the participant list for co-workers of the user because one or more of the known people to be added are determined to be co-workers of the user, and such a group is not already included in the participant list.
Alternatively or additionally, an existing group in the participant list to which each of the existing users is to be added may be identified (145). The existing group may be identified because one or more of the users of the existing group share a characteristic with each of the existing users to be added to the group, or because one or more of the users of the existing group are otherwise associated with each of the existing users. Alternatively or additionally, the existing group may be identified for each of the existing users because each of the existing users is included in a corresponding group in another contact list, such as the contact list that indicated that the existing users are known to the user.
In order to identify or create groups for the known people that have been identified for addition to the participant list, additional information describing the known people may be accessed. The additional information may identify characteristics of the known people that may be useful in identifying groups to which the known people should be added. In one implementation, profiles of the known people in the electronic communications system are accessed for use in identifying or creating groups to which the known people should be added.
The existing users that have been identified for addition to the participant list are then added to the participant list (150). In implementations where groups within the participant list have been identified for each of the existing users, the existing users are added to those groups. In implementations where groups have not been identified, the existing users are simply added to the list in general or to a default group within the list. For example, the existing users may be added to a general user group within the participant list.
In some implementations, the user of the electronic communications system whose participant list is maintained with the process 100 may use multiple identifiers when communicating over the electronic communications system. For example, the user may have a business identifier that is used with communicating during business hours or with business contacts, and a family identifier that is used when communicating with family members. The multiple identifiers may be linked such that the user may communicate using more than one of the multiple identities at a time. Furthermore, the user may maintain a participant list for each of the multiple identities. The participant list for a particular identifier may include other users with whom the user communicates using the particular identifier. For example, the participant list for the business identifier of the user may include the business contacts of the user, and the participant list for the family identifier may include the family member of the user. The participant lists for each of the multiple identities may be conglomerated into a single participant list that is maintained with the process 100.
When an existing user that is known to the user is added to the single participant list for the user during the process 100, an appropriate participant list within the single participant list for the existing user may be identified. For example, the existing user may be determined to be a business contact of the user, so the existing user may be added to the participant list corresponding to the business identifier of the user. The appropriate participant list for the existing user may be identified in a similar manner to how appropriate groups were identified or created for each of the identified users to be added to the participant list (140, 145).
In some implementations of the process 100, people known to the user that are not existing users of the electronic communications system may be added to the participant list of the user. When a person that is not an existing user of the electronic communications system is added to the participant list of the user, the person may be enabled to use the electronic communications system to communicate with the user. For example, the person may be made a trial user of the electronic communications system when the person is added to the participant list of the user with the process 100. The person then may choose to become a full user of the electronic communications system after being a trial user.

The buddy list interface 200 includes a text box 205 that contains the buddy list for the given user, who is identified by a screen name “AOLUser,” as indicated in the title bar 203 of the buddy list interface 200. The buddy list in the buddy list interface 200 includes multiple screen names 210a-210e. More particularly, the buddy list includes the screen name “Friend1” 210a, the screen name “Friend2” 210b, the screen name “Mom” 210c, the screen name “Dad” 210d, and the screen name “Sister” 210e.
The screen names within the buddy list shown by buddy list interface 200 are organized into multiple buddy groups 215a-215c. Each screen name within the buddy list is associated with at least one of the buddy groups 215a-215c. The buddy list includes a “Buddies” buddy group 215a, a “Family” buddy group 215b, and an “Offline” buddy group 215c. The screen name 210a appears below the heading for the buddy group 215a because the screen name 210a has been associated with the buddy group 215a and the corresponding user is present, that is, logged into the instant messaging system and available to send and receive instant messages. The heading for each of the buddy groups 215a and 215b indicates the number of buddies in the group currently logged into the instant messaging system, as well as the total number of buddies in the group. For example, two out of the two members of the buddy group 215a are logged into the instant messaging system for which the buddy list interface 200 is displayed. Similarly, the heading for the “Offline” buddy group 215c indicates the number of other users on the buddy list that are not logged into the system (i.e., 0) and the total number of buddies on the buddy list (i.e., 5). Typically, when users log into the instant messaging system, screen names of the users are moved from the “Offline” buddy group 215c to one of the other buddy groups 215a or 215b.
The buddy list interface 200 also includes controls 220 that enable the given user to communicate with the other selected users corresponding to the screen names 210a-210e. For example, the given user may send instant messages, chat invitations, or e-mail messages to the communications identities referenced in the buddy list through use of the controls 220. The controls 220 also enable the user to obtain information describing the other users, as well as to modify the set of other users referenced in the buddy list interface 200.
The buddy list interface 200 also includes controls 225 that enable the given user to access other information not directly related to sending and receiving instant messages. For example, the given user may use the controls to access e-mail messages or other special features of the instant messaging system. The given user also may use the controls 225 to modify preferences for the buddy list interface 200.

In some implementations of the buddy list interface 200, one of the buddy groups 215a and 215b may be designated as a default buddy group to which screen names are added when different groups for the screen names are not specified. For example, in the buddy list interface 200 illustrated in
Alternatively or additionally, specific groups to which the screen names 210f-210h are to be added may be identified during the process 100. The screen names 210f-210h may be added to one or more groups in the buddy list, and the one or more groups in the buddy list may need to be created before the screen names 210f-210h may be added, as is illustrated in the buddy list interface 200 of
The screen name 210g “Brother” was added to the buddy group 215b named “Family.” The screen name 210g may be added to the buddy group 215b because the user corresponding to the screen name 210g may share a characteristic or may be otherwise associated with the users corresponding to the other screen names 210c-210e included in the buddy group 215b (i.e., they are family members of the given user). The screen name 210g also may be added to the buddy group 215b because the user corresponding to the screen name 210g may be included in a corresponding group in another contact list, such as the contact list that was used during the process 100 to identify the user as being known to the given user.
The screen name 210h “Boss” has been added to a new buddy group 215d called “Co-Workers.” The user corresponding to screen name 210h is the only member of the new buddy group 215d and is presently logged into the instant messaging system, as indicated in the heading of the buddy group 215d. The buddy group 215d may be created for users corresponding to screen names in the participant list that have a certain characteristic, including the user corresponding to the screen name 210h (i.e. they are co-workers of the given user). As such, the buddy group 215d is created for the user corresponding to the screen name 215h. Other users that are co-workers of the given user may have their screen names added to the buddy group 215d of the participant list later.
The given user may be presented with a notification that screen names are being added automatically to the buddy list displayed in the buddy list interface 200. The given user may be enabled to accept the screen names to be added such that the automatically added screen names become visible in the buddy list interface 200. Alternatively, the given user may dismiss the screen names to be added, in which case, the screen names are not added to the displayed buddy list and are not visible in the buddy list interface 200. The given user also may be enabled to accept some of the screen names to be added and dismiss others of the screen names to be added.

The process 300 begins upon receipt of an indication that there is a new user of the electronic communications system (305). Such an indication may be received, for example, when the new user provides the electronic communications system with personal information, such as a name, address, and phone number, or billing information, such as a credit card or bank account number, that indicates that the new user is joining the electronic communications system. When the new user first joins the electronic communications system, the new user chooses or is assigned an identifier that is used to address messages sent to and from the new user within the electronic communications system. In addition, a participant list may be provided to the new user for use with the electronic communications system. The new user may access identifiers of other users of the electronic communications system that have been added to the participant list to address messages to be sent over the electronic communications system to the other users.
People that are known to the new user are identified (310). The known people may be identified from a contact list that includes contact information for people with whom the new user may communicate, as is done in the process 100 of
Communications strengths may be determined for each of the known people that is an existing user of the electronic communications system (320). The communications strengths may be calculated from one or more characteristics of the relationship between the new user and each of the existing users, as described above. Alternatively or additionally, the communications strengths may be indicated by the contact list from which the known people was identified, as described above. The known users with high communications strengths may be identified (325). More particularly, the known users with communications strengths above a threshold value that is indicative of a high communications strength may be identified.
The identified users of the electronic communications system may be sent a message that notifies the identified users of the identifier of the new user (330). The previously identified identifiers of the identified users may be used to address the notifications to the identified users. The notification may be sent as a type of message typically sent with the electronic communications system. For example, when the electronic communications system is an instant messaging system, the notifications may be sent as instant messages. As another example, the electronic communications system may be an e-mail system, and the notifications are sent as e-mail messages.
The identified users are enabled to add the identifier of the new user to participant lists used by the identified users (335). In some implementations, the notifications may include an indication of the identifier of the new user and a control that automatically adds the identifier of the new user to the participant lists of the identified users. The control may be a button or a link within the notification that may be selected. In other implementations, the identifier may be added to the participant lists when a response to the notifications is received. For example, when the notifications are sent to the identified users as instant messages, the identifier may be added to the participant lists when affirmative responses to the instant messages are received. In other implementations, the identified users may manually add the identifier to the participant lists when the notifications are received.
The new user is enabled to add the identified identifiers to the participant list that is used by the new user (340). The identifiers may be identified and added to the participant list through execution of the process 100 of
In some implementations, each of the existing users of the electronic communications system that are known to the new user may use multiple identifiers when communicating over the electronic communications system. The multiple identifiers may be linked such that each of the existing users may communicate using more than one of their multiple identities at a time, and a participant list may be maintained for each of the multiple identities. The participant lists for each of the multiple identities used by an existing user may be conglomerated into a single participant list for the existing user. When an existing user that is known to the new user is enabled to add an identifier of the new user to the single participant list for the existing user, a participant list within the single participant list for the existing user that is appropriate for the addition of the new user may be identified.

The instant messaging interface 400 includes a message history box 405 that lists the instant messages sent between the sender and the recipient. The message history box 405 also may be referred to as a message transcript box 405. Each message is presented with an indication of a screen name by which the sender or the recipient is identified as the sender of the message. Each message listed in the message history box 405 also includes the text of the instant message sent by the sender or the recipient. For example, the message history box 405 includes a message 406 sent by a user with a screen name “SystemMessage” and a message 407 sent by a user with a screen name “ExistingUser.” In one implementation, each message listed in the message history box 405 includes a time stamp of when the message was sent. The users that sent the messages 406 and 407 are the recipient and the sender, respectively.
The instant messaging interface 400 also includes a message specification box 410 in which the sender may specify a message to be sent to the recipient. The sender may enter text to be sent to the recipient in the message specification box 410. The instant message interface 400 includes a set of format controls 415 that may be used to format the text entered in the message specification box 410. More particularly, the controls in the set of format controls 415 enable the user to change the size, foreground color, background color, style, and effects of the text entered in the message specification box 410. The set of format controls 415 also includes controls for inserting objects that are not plain text, such as hyperlinks and emoticons, into the message specification box 410.
After a message has been specified in the message specification box 410, the message may be sent by selecting a send button 425 included in a second control set 420. After the send button 425 has been selected, the text that has been entered in the message specification box 410 is sent to the recipient, and the message specification box 410 is cleared. The message is added to the message history box 405. The message also is displayed in a message history box 405 of an instance of the instant messaging interface 400 being viewed by the recipient. Also included in the second control set 420 are controls for warning instant message senders, blocking instant messages from particular senders, or adding the sender to a participant list used by the sender.
The recipient with the screen name “SystemMessage” may be an instant messaging robot that automatically sends notifications of new users to existing users that are known to the new users, and the sender with the screen name “ExistingUser” may be one of those known existing users. The message 406 is a notification of a screen name of a new user of the instant messaging system that knows the sender. For example, the new user is named “John Smith” and has chosen “JohnSmith1” as a screen name to be used to identify himself in the instant messaging system. The message 407 is an affirmative response to the notification message 406. Upon receiving the affirmative response, the recipient (SystemMessage) automatically adds the screen name of the new user to a buddy list maintained for use by the sender (ExistingUser) such that the sender may select the new user's screen name to address instant messages to the new user.

The notification interface 450 includes a message 455 that informs the existing user of the identifier of the new user. For example, the message 455 illustrated in
The notification interface 450 also includes an accept button 460 that enables the existing user to import the e-mail address of the new user into an e-mail address book used by the existing user. When the existing user selects the accept button 460, the e-mail address of the new user is added to the address book of the existing user. The notification interface 450 also includes a reject button 465 that, when selected, dismisses the notification interface 450 without first adding the e-mail address of the new user to the address book of the existing user.

Initially, the participant list used by the user is maintained (605). The user may use the participant list to communicate with the other users included in the participant list. The participant list includes one or more identifiers of the other users, and the user may select an identifier from the participant list to address a message to be sent to the corresponding user with the electronic communications system. The identifiers included in the participant list may be separated into one or more groups that categorize or otherwise organize the other users. The location of the identifier within the participant list may affect how quickly and easily the user may find and select the identifier and send the message.
Communications strengths are determined for each of the users included in the participant list (610). The communications strengths may be calculated from one or more characteristics of the relationship between the new user and each of the known users, as described above.
An additional group within the participant list may be provided (615). Copies of the identifiers of some or all of the users included in the participant list may be organized within the additional group. In one implementation, the additional group is added to the end of the participant list below other existing groups within the participant list. Organizing copies of the identifiers within the additional group does not disrupt the organization of other copies of the identifiers included in other existing groups of the participant list. Therefore, the user may access the unorganized identifiers, with which the user may be more familiar, or the organized identifiers in the additional group when accessing identifiers to address messages to the corresponding users of the electronic communications system.
The users included in the participant list may be organized based on communications strength in the additional group (620). In one implementation, second copies of identifiers of users with higher communications strengths are placed above identifiers of users with lower communications strengths in the additional group. All users included in the participant list are organized within the additional group, so the participant list includes two copies of an identifier of each of the users included in the participant list. Copies of the identifiers in the other existing groups are not organized by communications strength.
Alternatively, only some of the users included in the participant list may be organized based on communications strength in the additional group. For example, the users with the highest communications strengths may be organized in the additional group (625). Identifiers of users with higher communications strengths may be placed above identifiers of users with lower communications strengths in the additional group. In one implementation, identifiers of a particular number of the users with the highest communications strengths are organized within the participant list. In another implementation, identifiers of the users with communications strengths above a threshold value are organized within the additional group. Only some of the users of the participant list are organized within the additional group, so the participant list includes two copies of an identifier of some of the users included in the participant list. Copies of the identifiers in the other existing groups remain unorganized.
When the additional group is not provided within the participant list, the users included in the participant list are organized in place based on corresponding communications strengths (630). Doing so may change the order in which the identifiers of the included users appear in the participant list. Identifiers of users with higher communications strengths may be placed above identifiers of users with lower communications strengths within each group of the participant list. In such implementations, the participant list includes a single copy of each different identifier, and no identifiers are moved or copied between groups.
Identifiers of the users included in the participant list corresponding to the lowest communications strengths may be removed from the participant list (635). For example, identifiers of the users corresponding to communications strengths that are below a threshold value may be removed from the participant list. A low communications strength for a particular user is indicative of a weak relationship between the particular user and the user. As such, the user most likely does not communicate with the particular user very often, and the user most likely does not access an identifier of the particular user included in the participant list to address a message to the particular user very often. Therefore, the identifier of the particular user, and other users included in the participant list corresponding to the lowest communications strengths, may be removed from the participant list. As an alternative to removal, these users may be moved to a special group designated as being for users with lower communications strengths.
In some implementations, the user of the electronic communications system whose participant list is maintained with the process 600 may use multiple identifiers when communicating over the electronic communications system. The multiple identifiers may be linked such that the user may communicate using more than one of the multiple identities at a time. Furthermore, the user may maintain a participant list for each of the multiple identities, and the participant list for a particular identifier may include other users with whom the user communicates using the particular identifier. The participant lists for each of the multiple identities may be conglomerated into a single participant list that is maintained with the process 600.
When organizing the participant list of the user with the process 600, the multiple participant lists corresponding to the user may be organized individually. In addition, an additional participant list may be added to the single participant list for the user. The additional participant list may include one or more users from one or more of the multiple participant lists for the user in an organized manner, in a manner similar to how users of the participant list were organized within an additional group within the participant list (620, 625).

Organizing the screen names 210a-210e within the groups with which the screen names 210a-210e are associated indicates the relative communications strengths of the users corresponding to a particular group. However, the relative communications strengths of users whose screen names are associated with different buddy groups are not easily seen with such an organization. Organizing the screen names 210a-210e without reference to a particular buddy group indicates the relative communications strengths of users whose screen names are associated with different buddy groups.

The described techniques for augmenting and organizing participant lists of identifiers used in sending and receiving electronic messages may be applied to any type of participant list associated with any type of electronic communications system. For example, a buddy list used with an instant messaging system, an e-mail address book used with an e-mail system, a list of users of a social network used with a social networking system, or any other list of contact information that includes information that may be used to contact other people, may be automatically augmented with contact information of known people. The same contact lists may be organized to facilitate accessing and selecting contact information that may be used to contact other people.

The user device 820 (or the provider device 835) is generally capable of executing instructions under the command of a user controller 825 (or a provider controller 840). The user device 820 (or the provider device 835) is connected to the user controller 825 (or the provider controller 840) by a wired or wireless data pathway 830 or 845 capable of delivering data.
Each of the user device 820, the user controller 825, the provider device 835, and the provider controller 840 typically includes one or more hardware components and/or software components. An example of a user device 820 or a provider device 835 is a general-purpose computer (e.g., a personal computer) capable of responding to and executing instructions in a defined manner.

The user device 920 typically includes a general-purpose computer 970 having an internal or external storage 972 for storing data and programs such as an operating system 974 (e.g., DOS, Windows™, Windows 95™, Windows 98™, Windows 2000™, Windows Me™, Windows XP™, Windows NT™, OS/9, or Linux) and one or more application programs. Examples of application programs include authoring applications 976 (e.g., word processing programs, database programs, spreadsheet programs, or graphics programs) capable of generating documents or other electronic content; user applications 978 (e.g., AOL user, CompuServe user, AIM user, AOL TV user, or ISP user) capable of communicating with other computer users, accessing various computer resources, and viewing, creating, or otherwise manipulating electronic content; and browser applications 980 (e.g., Netscape's Navigator or Microsoft's Internet Explorer) capable of rendering standard Internet content and also capable of supporting a web-based e-mail user and a web-based instant messaging user.
The general-purpose computer 970 also includes a central processing unit 982 (CPU) for executing instructions in response to commands from the user controller 925. In one implementation, the user controller 925 includes one or more of the application programs installed on the internal or external storage 972 of the general-purpose computer 970. In another implementation, the user controller 925 includes application programs externally stored in and performed by one or more device(s) external to the general-purpose computer 970.
The general-purpose computer typically will include a communication device 984 for sending and receiving data. One example of the communication device 984 is a modem. Other examples include a transceiver, a set-top box, a communication card, a satellite dish, an antenna, or another network adapter capable of transmitting and receiving data over the communications link 915 through a wired or wireless data pathway 950. The general-purpose computer 970 also may include a TV tuner 986 for receiving television programming in the form of broadcast, satellite, and/or cable TV signals.

The provider system 1010 includes a provider device 1035 and a provider controller 1040. The provider controller 1040 is generally capable of transmitting instructions to any or all of the elements of the provider device 1035. For example, in one implementation, the provider controller 1040 includes one or more software applications loaded on the provider device 1035. In other implementations, as described above, the provider controller 1040 may include any of several other programs, machines, and devices operating independently or collectively to control the provider device.
The provider device 1035 includes a login server 1070 for enabling access by subscribers and for routing communications between the user system 1005 and other elements of the provider device 1035. The provider device 1035 also includes various provider complexes such as the depicted OSP (“Online Service Provider”) provider complex 1080 and IM (“Instant Messaging”) provider complex 1090. To enable access to these provider complexes by subscribers, the user system 1005 includes communication software, for example, an OSP user application and an IM user application. The OSP and IM communication software applications are designed to facilitate the subscriber's interactions with the respective services and, in particular, may provide access to all the services available within the respective provider complexes.
Typically, the OSP provider complex 1080 supports different services, such as e-mail, discussion groups, chat, news services, and Internet access. The OSP provider complex 1080 is generally designed with an architecture that enables the machines within the OSP provider complex 1080 to communicate with each other and employs certain protocols (i.e., standards, formats, conventions, rules, and structures) to transfer data. The OSP provider complex 1080 ordinarily employs one or more OSP protocols and custom dialing engines to enable access by selected user applications. The OSP provider complex 1080 may define one or more specific protocols for each service based on a common, underlying proprietary protocol.
The IM provider complex 1090 is generally independent of the OSP provider complex 1080, and supports instant messaging services irrespective of a subscriber's network or Internet access. Thus, the IM provider complex 1090 allows subscribers to send and receive instant messages, whether or not they have access to any particular ISP. The IM provider complex 1090 may support associated services, such as administrative matters, advertising, directory services, chat, and interest groups related to instant messaging. The IM provider complex 1090 has an architecture that enables all of the machines within the IM provider complex to communicate with each other. To transfer data, the IM provider complex 1090 employs one or more standard or exclusive IM protocols.
The provider device 1035 may include one or more gateways that connect and therefore link complexes, such as the OSP provider complex gateway 1085 and the IM provider complex gateway 1095. The OSP provider complex gateway 1085 and the IM provider complex gateway 1095 may directly or indirectly link the OSP provider complex 1080 with the IM provider complex 1090 through a wired or wireless pathway. Ordinarily, when used to facilitate a link between complexes, the OSP provider complex gateway 1085 and the IM provider complex gateway 1095 are privy to information regarding the protocol type anticipated by a destination complex, which enables any necessary protocol conversion to be performed incident to the transfer of data from one complex to another. For instance, the OSP provider complex 1080 and IM provider complex 1090 generally use different protocols such that transferring data between the complexes requires protocol conversion by or at the request of the OSP provider complex gateway 1085 and/or the IM provider complex gateway 1095.
The described techniques result in the population and organization of participant lists for electronic communications systems. Presence and location of a user in a participant list is indicative of the communications strength of the user with another user that uses the participant list. As a result, participant lists populated and organized with the described techniques may inform the population and organization of other participant lists. For example, when a buddy list of an instant messaging system is organized with the process 600 of
In another example, when a buddy list of an instant messaging system is populated using the process 100 of
The described techniques may be applied when a user first becomes a user of an electronic communications system, at which point the user receives a new personal identifier and a corresponding participant list for use with the electronic communications system. The described techniques also may be applied when the user changes their identifier, or when the user chooses an additional identifier. For example, people known to the user may be notified of the changed or additional identifier such that those people may add the changed or additional identifier to their personal participant lists. People known to the user may be added to participant lists corresponding to the changed or additional identifier, and the participant lists corresponding to the changed or additional identifier may be organized. Population and organization of the participant lists for the changed or additional identifier may occur separately for each of those participant lists, or together for all of the participant lists corresponding to the user, as described above.
A participant list of a user of an electronic communications system may be dynamically maintained by calculating communications strengths between the user and people known to the user multiple times on a periodic or aperiodic basis. As messages are sent and received by the user, and as the relationships between the users and the known people change, the communications strengths between the user and the known people may change, and the communications strengths may be calculated multiple times to account for that change. For example, the communications strength between the user and one of the known people may be calculated each time a message is sent to or from that known person. The population and organization of the participant list of the user may be updated according to the process 100 of
The described systems, methods, and techniques may be implemented in digital electronic circuitry, computer hardware, firmware, software, or in combinations of these elements. Apparatus embodying these techniques may include appropriate input and output devices, a computer processor, and a computer program product tangibly embodied in a machine-readable storage device for execution by a programmable processor. A process embodying these techniques may be performed by a programmable processor executing a program of instructions to perform desired functions by operating on input data and generating appropriate output. The techniques may be implemented in one or more computer programs that are executable on a programmable system including at least one programmable processor coupled to receive data and instructions from, and to transmit data and instructions to, a data storage system, at least one input device, and at least one output device. Each computer program may be implemented in a high-level procedural or object-oriented programming language, or in assembly or machine language if desired; and in any case, the language may be a compiled or interpreted language. Suitable processors include, by way of example, both general and special purpose microprocessors. Generally, a processor will receive instructions and data from a read-only memory and/or a random access memory. Storage devices suitable for tangibly embodying computer program instructions and data include all forms of non-volatile memory, including by way of example semiconductor memory devices, such as Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and Compact Disc Read-Only Memory (CD-ROM). Any of the foregoing may be supplemented by, or incorporated in, specially-designed ASICs (application-specific integrated circuits).
It will be understood that various modifications may be made without departing from the spirit and scope of the claims. For example, advantageous results still could be achieved if steps of the disclosed techniques were performed in a different order and/or if components in the disclosed systems were combined in a different manner and/or replaced or supplemented by other components.
