In operation S210, the device 1000 may extract summary information from the interaction data. The device 1000 may extract summary information corresponding to important information from the interaction data. The important information may include subject information, contact information, group information, a relationship with a contact, urgency of the interaction data, and/or a correlation between a user and the interaction data. The relationship with a contact may be acquired by analyzing information related to the contact and/or an interaction history with the contact, where the information related to the contact may include contact information in an address book, a schedule related to the contact in a scheduling table and/or memorandum, or contact information in a social network application. The interaction history with the contact may include a call history with the contact, a short message history with the contact, an email history with the contact, and/or an interaction history with the contact in other social network applications.

In addition, the device 1000 may classify the summary information according to at least one piece of information among an interaction time of the interaction data, a matter of interest of the user, a relationship with the contact, an appointment of the contact in the summary information, and an appointment of the user in the summary information and extract the classified summary information.

For example, when the important information is subject information, the device 1000 may display the important information in an order determined according to the popularity of each subject, a correlation between the user and each subject, importance of the user in each subject, and/or a predetermined subject. As another example, when the important information is contact information, the device 1000 may display the important information in an order determined according to a contact frequency with the contact, a relationship with the contact, and/or a predetermined contact.

A correlation between a subject and the matter of interest of the user may be acquired by analyzing an activity history of the user and determining the correlation between the subject and the matter of interest of the user. The activity history may include searching for contacts, clicking on contacts, transmitting contacts, and/or editing contacts.

According to an exemplary embodiment, the important information may include predetermined event information, and the device 1000 may extract summary information corresponding to the predetermined event information from the interaction data. The predetermined event information may include predetermined content mentioned in the interaction data, responded predetermined content, information regarding a predetermined contact who has transmitted interaction content, and/or content related to a predetermined subject.

In operation S220, the device 1000 may output the summary information. The device 1000 may display important information, and then output summary information corresponding to the important information when a user input related to the displayed important information is received. In addition, the device 1000 may output classified summary information.

According to an exemplary embodiment, the device 1000 may output prompt information about a predetermined event, and then output summary information corresponding to the predetermined event when a user input related to the prompt information is detected.

According to another exemplary embodiment, the device 1000 may generate summary information by editing summary content in which interaction data is summarized. Alternatively, the device 1000 may generate summary information by editing summary content corresponding to important information.

The operation in which the device 1000 outputs the summary information may include processing the summary information and outputting the processed summary information, the processing being performed by using a method of acquiring information about each contact corresponding to summary information about interaction data and generating customized summary information corresponding to each contact; a method of generating relevant summary information corresponding to summary content of interaction data; a method of generating multimedia summary information according to text summary information and multimedia information in summary content of interaction data; a method of detecting predetermined content and/or a predetermined contact to be blocked in summary content of interaction data and then blocking data related to the predetermined content and/or the predetermined contact in the summary content; and/or a method of generating summary information about a current situation and/or a current device state according to current situation information and/or current device state information about a terminal device.

In the method of acquiring information about each contact corresponding to summary information about interaction data and generating customized summary information corresponding to each contact, the contact information may include a chat habit of a contact, a relationship between the contact and the user, and/or attribute information about the contact. In addition, the chat habit of the contact may include a word used by the contact with high frequency, a phrase used by the contact with high frequency, a sentence structure used by the contact with high frequency, and/or an expression by the contact with high frequency. In addition, the attribute information about the contact may include a job, an age, a gender, and/or an image of the contact. In addition, the chat habit of the contact may be acquired by analyzing an interaction history with the contact. In addition, the attribute information about the contact may be acquired by analyzing information about the contact and/or the interaction history with the contact.

According to the method of generating relevant summary information corresponding to summary content of interaction data, when content for requesting for responses from a plurality of contact is included in the summary content of the interaction data, responses of the contact may be collected to configure relevant summary information. Alternatively, when content for requesting for a response of the user is included in the summary content of the interaction data, a conflict between the content for requesting for a response of the user and a schedule of the user or a conflict between the content for requesting for a response of the user and a current place is detected, and then relevant summary information including a conflict alert may be generated. Alternatively, when content related to a hot event (e.g., an noteworthy event, an upcoming event, etc.) is included in the summary content of the interaction data, information related to the hot event is searched for, and relevant summary information including retrieved information may be generated.

In the method of generating multimedia summary information according to text summary information and multimedia information in summary content of interaction data, the multimedia summary information may include background music, video, image, speech, and/or text summary information.

The method of generating summary information about a current situation and/or a current device state according to current situation information and/or current device state information about a terminal device may include: determining a current state of the user according to the current situation information and/or the current device state information; and generating summary information including semantic characteristics corresponding to the current state of the user.

According to an exemplary embodiment, the method of FIG. 2 may further include detecting, by the device 1000, a user input on a region related to the output summary information and then moving to a display interface for displaying interaction data corresponding to the summary information. According to an exemplary embodiment, when the summary information corresponds to at least two contact groups, the device 1000 may display interaction data corresponding to the summary information in groups corresponding to the contact groups in the display interface.

According to an exemplary embodiment, the outputting of the summary information extracted from the interaction data may be performed by using a predetermined speech characteristic, outputting summary information corresponding to a contact as a speech by using a speech characteristic of the contact, determining a speech pattern according to a speech characteristic and current situation information and/or current device state information about a terminal device and outputting summary information as a speech by using the speech characteristic and the speaking manner.

In addition, the speech characteristic of the contact may be acquired by collecting speech segments of the contact and acquiring a speech characteristic of the contact from the collected speech segments or by predicting a speech characteristic according to attribute information about the contact and/or an interaction history with the contact.

When a speech characteristic is acquired from collected speech segments, the method of FIG. 2 may include: learning a speech model for synthesis by using the collected speech segments of the contact; and acquiring a speech characteristic customized to the contact.

According to an exemplary embodiment, the device 1000 may analyze interaction data to acquire content for requesting for a response of the user and generate and output a response customized according to the acquired content.

When the device 1000 generates and outputs a response customized according to content for requesting for a response of the user, the device 1000 may process the content for requesting for a response of the user according to a relationship with a contact by which the response is to be received, attribute information about the user, and/or attribute information about the contact by which the response is to be received in order to generate and output the customized response.

When the device 1000 outputs summary information extracted from interaction data, the device 1000 may classify the summary information according to an interaction time of the interaction data, a topic of interest of the user, a relationship with a contact, an appointment of the contact in the summary information, and/or an appointment of the user in the summary information, and output the classified summary information.

FIG. 3 is a flowchart of a method of providing guidance information about messages in a primary chat window, according to some exemplary embodiments.

In operation S300, the device 1000 may acquire a plurality of messages included in at least one chat window. The device 1000 may transmit and receive messages to and from other devices through a chat window and monitor the messages transmitted and received through the chat window. The device 1000 may identify whether the acquired messages have been read by the user of the device 1000. In addition, the device 1000 may acquire, from a chat window, messages from other devices for a preset time duration.

When a plurality of chat applications are installed in the device 1000, the device 1000 may acquire messages received from other devices by monitoring chat windows provided by the plurality of chat applications.

In operation S320, the device 1000 may determine that a preset event has occurred, based on the acquired plurality of messages. The device 1000 may determine that the preset event has occurred, based on a message received from another device and not read by the user of the device 1000 from among messages in a chat window. The preset event may be preset by the user, and when it is determined that content of a message indicates a preset situation, it may be determined that the preset event has occurred.

For example, the device 1000 may use various natural language analysis schemes to understand the meaning of an acquired message and determine whether the preset event has occurred, based on the meaning of the acquired message. For example, when a message including the name of the user of the device 1000 is received, when a message is received from a preset other user, when a message related to a predetermined subject set by the user is received, when a message related to predetermined content set by the user is received, or when a message is received from some users selected from among users in a chat window, it may be determined that the preset event has occurred, but the present exemplary embodiment is not limited thereto.

In addition, the device 1000 may change the preset event by receiving a user input for changing an event. When the device 1000 determines that the preset event has occurred, from the plurality of messages acquired from the chat window, the device 1000 may proceed to operation S340.

In operation S340, the device 1000 may generate the secondary chat window 3000 for informing the user about the occurred event. The device 1000 may add the user of the device 1000 and the device 1000 itself as participants in the chat room of the secondary chat window 3000, and the user may communicate with the device 1000 in the secondary chat window 3000 as if the device 1000 is another user to communicate with. The device 1000 may match a plurality of primary chat windows with the secondary chat window 3000 and generate the secondary chat window 3000 to inform the user of information regarding events respectively occurring in the plurality of primary chat windows.

When the preset event has occurred, the device 1000 may automatically generate the secondary chat window 3000 but the disclosure is not limited thereto. When the preset event has occurred, the device 1000 may display a graphic user interface (GUI) for asking the user whether the user wishes to receive guidance information through the secondary chat window 3000, and generate the secondary chat window 3000 when a user input for receiving guidance information is input through the GUI.

In operation S360, the device 1000 may display guidance information about the occurred event in the secondary chat window 3000. The guidance information may indicate the occurrence of the event to the user and may include, for example, a summary message for informing the user about the occurred event, a comment message for providing to the user a comment related to the occurred event, search information retrieved by the device 1000 related to the occurred event, and a recommended response message for recommending a response of the user in relation to the event, but the disclosure is not limited thereto.

In addition, the device 1000 may display the guidance information in the secondary chat window 3000 in a form of a chat message to the user. For example, the device 1000 may display a speech bubble including the guidance information in the secondary chat window 3000 together with a predetermined identification value associated with the device 1000. In addition, the device 1000 may receive a user input for inputting a message through the secondary chat window 3000 and input the input message into a chat window corresponding to the input message.

FIG. 4 is a flowchart of a method of determining the occurrence of a preset event in a primary chat window, according to some exemplary embodiments.

In operation S400, the device 1000 may set events for each category. The device 1000 may select a predetermined category by receiving a user input and set a predetermined event related to the selected category. A category may be a criterion for identifying a message type. For example, the category may be identified according to a subject of a dialogue or a subject of a message, such as “food” or “sports.” However, the present exemplary embodiment is not limited thereto, and a category may be identified according to, for example, an identify of a user of another device 1000 which has transmitted a message or an operation of the device 1000 requested by a message.

For example, the device 1000 may select a category, “receiving a message”, and set an event, “receiving a message from a user A” as a priority event. Even after setting events for each category, the device 1000 may change a category and/or an event by receiving a user input for changing the category and/or the event.

In operation S420, the device 1000 may identify a keyword included in at least one message. The device 1000 may identify at least one keyword from messages acquired from at least one chat window. The device 1000 may identify a keyword from a message according to a set event. In this case, keywords corresponding to events may be assigned for each event.

In operation S440, the device 1000 may analyze the meaning of a message including the keyword. The device 1000 may analyze the meaning of a message that includes a keyword related to an event from among messages in a primary chat window. In addition, the device 1000 may analyze the meaning of the messages displayed immediately before and after the message including a keyword related to an event from among messages in a primary chat window.

In addition, the device 1000 may analyze the meaning of a message by using various natural language analysis schemes. For example, the device 1000 may analyze the meaning of a message by dividing a sentence included in the message, analyze morphemes in the sentence, and/or analyzing vocabulary of words in the sentence, but the disclosure is not limited thereto.

In operation S460, the device 1000 may determine the occurrence of a preset event. The device 1000 may determine whether the preset event has occurred in a primary chat window, based on the meaning of the message, which has been analyzed in operation S440. For example, the device 1000 may determine which category of events a message is related to, based on the meaning of the message and determine which event from among the events in the determined category has occurred based on the message. In addition, for example, when a predetermined keyword is included in a message, the device 1000 may determine that the preset event has occurred. Alternatively, even when a predetermined keyword is included in a message, the device 1000 may determine that the preset event has not occurred, according to the meaning of the message.

FIG. 5 is a flowchart of a method of displaying guidance information about an occurred event in the secondary chat window 3000 when the preset event has occurred, according to some exemplary embodiments.

In operation S500, the device 1000 may display a summary message of an occurred event. The device 1000 may generate a summary message of an occurred event and display the generated summary message in the secondary chat window 3000. The device 1000 may generate a summary message of an occurred event by analyzing the meaning of at least one message associated with the occurrence of the event. For example, the device 1000 may generate a summary message including an identification value of a user of another device, which has transmitted a message that caused the occurrence of an event and a phrase describing the occurred event. For example, the phrase describing the occurred event may be the same as the message which has caused the occurrence of the event but is not limited thereto. For example, the device 1000 may generate the phrase describing the occurred event by editing the message which has caused the occurrence of the event. The phrase describing the occurred event may include brief content including only basic information included in the message. The basic information may be, for example, a keyword indicating the time and/or place in the message which has caused the occurrence of the event but is not limited thereto.

In addition, the device 1000 may generate the phrase describing the occurred event with reference to a manner of speaking (i.e., speech pattern) of the user of the other device that transmitted the message which has caused the occurrence of the event. The manner of speaking or the speech pattern of the user may refer to a dialect, an accent, a linguistic idiosyncrasy, a characteristic, and/or vocabulary, commonly associated with the user. In this case, the way of speaking of the user of the other device may be determined by analyzing messages transmitted in the past by the user of the other device. In addition, the way of speaking of the user of the other device may be stored in a memory in the device 1000 and matched with the identity of the user of the other device.

In operation S520, the device 1000 may display a comment message related to the occurred event. The comment message may be a message indicating a comment related to an event related to a message in a primary chat window. For example, the comment message may include information indicating matters to which the user refers to input a response message related to the occurred event. For example, the device 1000 may display, in the secondary chat window 3000, a comment message including information indicating that the occurred event overlaps with another scheduled event of the user. In this case, for example, the device 1000 may extract a user schedule registered in the device 1000 or a predetermined web service and determine whether the occurred event conflicts with the user's schedule. In addition, the device 1000 may generate a comment message indicating that the occurred event overlaps with a pre-registered schedule of the user. In addition, the comment message may include content inducing a response of the user. For example, the device 1000 may generate a comment message for informing that the prescheduled event of the user is an important event or a comment message for informing that the user's schedule requires an adjustment, but the disclosure is not limited thereto.

In addition, the device 1000 may cause messages related to a predetermined event to be blocked. When a message causing the occurrence of an event set to be blocked is received, the device 1000 may display, in the secondary chat window 3000, a comment message indicating that the message related to the occurred event has been blocked. In addition, the comment message indicating that the message has been blocked may include an identification value of another user who has transmitted the message causing the occurrence of the event set to be blocked. Alternatively, when a message causing the occurrence of an event set to be blocked is received, the device 1000 may ignore the received message and may not display information regarding the received message in the secondary chat window 3000.

In operation S540, the device 1000 may display search information about the occurred event. The device 1000 may search for information related to the occurred event and display retrieved search information in the secondary chat window 3000. For example, the device 1000 may display the retrieved search information in the secondary chat window 3000 or display link information for accessing the retrieved search information in the secondary chat window 3000. In addition, the device 1000 may edit the retrieved search information and display the edited information in the secondary chat window 3000.

In operation S560, the device 1000 may display a recommended response message related to the occurred event. The recommended response message may be a message including a response recommended to the user as a response of the user, which is related to the occurred event. In addition, for example, the device 1000 may analyze the occurred event and determine a recommended response related to the occurred event in consideration of a schedule of the user, a status of the device 1000, a status of the user, and the like. Information indicating the status of the device 1000 and the status of the user may be acquired from, for example, a sensor included in the device 1000 or communicating with the device 1000, a server, and/or another device. The device 1000 may display the recommended response message related to the occurred event in the secondary chat window 3000.

FIGS. 6A and 6B illustrate the device 1000 providing a comment message based on a user schedule, according to some exemplary embodiments.

Referring to FIG. 6A, the user of the device 1000 may send and receive messages in a primary chat window 2060 with at least one other user. When the user of the device 1000 sends a message 600 to other users in the chat window 2060, the device 1000 may determine a category of messages in the chat window 2060 by analyzing the messages. In addition, when a message 610 including a specific keyword corresponding to the determined category is received, the device 1000 may determine whether a specific event related to the determined category has occurred by analyzing the meaning of the message 610. For example, the device 1000 may assign a category, “appointment”, by analyzing the messages in the chat window 2060. In addition, the device 1000 may identify the words “evening” and “8 o'clock” included in the message 610 and determine that a message proposing a meet-up has been received, by analyzing the meaning of the message 610.

As shown in FIG. 6B, when the device 1000 determines that the preset event related to the determined category has occurred, as a result of analyzing the meaning of the message 610, the device 1000 may generate a secondary chat window 3060. A message 620, which is identical to the message 610 from another user in the primary chat window 2060, may be displayed in the newly generated secondary chat window 3060. The device 1000 may generate a comment message 630 related to the occurred event by using schedule information about the user and display the generated comment message 630 in the secondary chat window 3060.

FIG. 9 is a flowchart of a method of providing, to another user through a chat window, a response message input from a user through the secondary chat window 3000, according to some exemplary embodiments.

In operation S900, the device 1000 may receive a first response input of the user who responds to the occurrence of an event and display the received first response input in the secondary chat window 3000. The device 1000 may display a message related to the occurred event in the secondary chat window 3000 and receive the first response input of the user who inputs a response to the displayed message. The first response input of the user may be a simple response including at least one word. For example, the first response input of the user may not be a complete sentence and may include only a few keywords related to content which the user desires to respond to. The first response input of the user may be a text input and/or a speech input but is not limited thereto.

Alternatively, when a plurality of events occur, and a plurality of messages related to the plurality of events are displayed in the secondary chat window 3000, the user may input first response inputs respectively corresponding to the plurality of events.

In operation S920, the device 1000 may generate a recommended response message based on the first response input and display the generated recommended response message in the secondary chat window 3000. The device 1000 may generate the recommended response message based on content of the occurred event and words included in the first response input. For example, the device 1000 may generate a response related to the occurred event in a form of a complete sentence by using the words included in the first response input.

Alternatively, when a plurality of events occur, and a plurality of first response inputs respectively corresponding to the plurality of events are input, the device 1000 may generate a plurality of recommended response messages respectively corresponding to the plurality of events. Alternatively, when the user inputs first responses to some of the plurality of events, the device 1000 may generate recommended response messages related to the events respectively corresponding to the input first response inputs, based on the input first response inputs. Alternatively, when the user inputs responses to some of the plurality of events, the device 1000 may generate recommended response messages related to events for which first response inputs of the user have not been input, in consideration of the input first response inputs of the user.

In addition, the device 1000 may generate the recommended response message in consideration of a phrase frequently used by the user and a relationship between the user and the other user but is not limited thereto. For example, the device 1000 may store and manage information regarding a history of messages transmitted and received by the user to and from the other user through a chat application and content shared by the user with the other user, and determine the phrase frequently used by the user and the relationship between the user and the other user based on the stored information.

In operation S940, the device 1000 may receive a second response input of the user in response to the recommended response message and display the received second response input in the secondary chat window 3000. The user may input the second response input related to whether to agree to transmit the recommended response message recommended by the device 1000 to the other user. Alternatively, the user may input the second response input for editing the recommended response message recommended by the device 1000. Alternatively, the user may input the second response input for designating recipient of the recommended response message so that it is determined to whom the recommended response message recommended by the device 1000 is transmitted. Alternatively, the device 1000 may receive the second response input indicating which portion of the recommended response message is to be transmitted to another user. Alternatively, the device 1000 may receive the second response input for requesting the device to provide another recommended response message. In this case, the device 1000 may generate another recommended response message and display the generated other recommended response message in the secondary chat window 3000. The second response input of the user may be a text input and/or a speech input but is not limited thereto.

In operation S960, the device 1000 may generate or determine a final response message to be provided to the other user, based on the second response input, and display the generated or determined final response message in the secondary chat window 3000.

In operation S980, the device 1000 may provide the final response message to the other user through a chat window corresponding to the final response message.

For example, when a plurality of events occur in a plurality of chat windows, respectively, and when a plurality of final response messages respectively corresponding to the plurality of events are determined, the device 1000 may input the plurality of final response messages in the plurality of chat windows corresponding to the plurality of final response messages, respectively.

In addition, for example, when the user communicates with a plurality of other users in a chat window, and the user inputs the second response input such that the second response input is transmitted to some of the plurality of other users, the device 1000 may provide the final response message to only some of the plurality of other users. In this case, the device 1000 may input and display the final response message in the chat window and display, together with the final response message, an identification value indicating to whom of the other users in the chat window the input final response message is provided.

FIG. 13 is a flowchart of a method of outputting, as a speech, a summary message of an occurred event, according to some exemplary embodiments.

In operation S1301, the device 1000 may determine whether an event has occurred from a plurality of messages included in at least one chat window.

In operation S1321, the device 1000 may generate a summary message of the occurred event.

In operation S1341, the device 1000 may identify another user related to the occurred event.

In operation S1361, the device 1000 may modify the summary message according to a characteristic of the identified other user. For example, the device 1000 may modify the summary message based on information regarding a phrase frequently used by the identified user and/or relationship information between the user and the other user, but the disclosure is not limited thereto. For example, the device 1000 may adjust a tone of the generated summary message according to a speech pattern of the other user. In addition, the device 1000 may cumulatively collect information to be used as a basis for modifying the summary message, from messages of other users in a chat window, but is not limited thereto.

In operation S1381, the device 1000 may output the modified summary message as a speech of the other user. In this case, speech information about the speech of the other user may be stored in advance, and the device 1000 may output the summary message as a synthesized speech of the other user by using the stored speech information.

FIG. 14 is a flowchart of a method of outputting, as a speech, a summary message of an occurred event according to the existence of a speech segment, according to some exemplary embodiments.

In operation S1401, the device 1000 may determine whether a speech segment of another user exists in a storage. The device 1000 may cumulatively store, for example, a call history of the other user and speech data received from the other user, and the device 1000 may determine whether a speech segment of the other user exists.

If it is determined as a result of the determination in operation S1401 that a speech segment of the other user exists, the device 1000 may acquire a speech characteristic of the other user by using the speech segment of the other user in operation S1411. For example, the device 1000 may collect speech segments of the other user, then acquire a text corresponding to the collected speech segments by using a speech recognition method, and generate a speech learning model of the other user by using the acquired text. In addition, the device 1000 may acquire a speech characteristic of the other user by using the generated speech learning model of the other user.

In operation S1421, the device 1000 may output, as a speech of the other user, a summary message of a message received from the other user by applying the speech characteristic of the other user.

If it is determined as a result of the determination in operation S1401 that no speech segment of the other user exists, the device 1000 may predict the speech characteristic of the other user in operation S1431. For example, the device 1000 may predict the speech characteristic of the other user by using attribute information about the other user and messages received from the other user but is not limited thereto. The attribute information about the other user may include a gender and an age of the other user but is not limited thereto. The speech characteristic of the other user thus predicted may be an approximation of the speech of the other user based on the attribute information and the messages.

In operation S1441, the device 1000 may output, as a speech, the summary message by applying the predicted speech characteristic of the other user. The speech may be a synthesized speech utterance.

According to another exemplary embodiment, a speech characteristic for a summary message to be output as a speech may be determined based on state information about the device 1000. The state information about the device 1000 may include time and place information, motion information about the device 1000, and the like. The device 1000 may acquire the state information about the device 1000 through a microphone, a photosensor, a speed sensor, and the like. For example, when the user uses the device 1000 during work at an office in the afternoon, the device 1000 may output summary information briefly and quickly by applying a speech characteristic of a broadcast announcer so as not to disturb the work, based on acquired state information about the device 1000. However, the present exemplary embodiment is not limited thereto.

In addition, the device 1000 may display identification values indicating the levels of the other users in the chat window and the secondary chat window 3000. The level may indicate priority assigned to each of the users.

In operation S1511, the device 1000 may edit a message to be provided to the other user through the secondary chat window 3000, based on the set level. For example, the user may set the level of the other user as an important level (i.e., high priority), and the device 1000 may display, in the secondary chat window 3000, only a summary message related to a message received from the other user set to the important level. In addition, the device 1000 may provide a message input by the user through the secondary chat window 3000 only to the other user set to the important level.

For example, the user may set the level of the other user as a blocking level (i.e., low priority), and the device 1000 may not generate a summary message of a message received from the other user set to the blocking level. In addition, when a summary message of a message received from the other user set to the blocking level is already displayed in the secondary chat window 3000, the displayed summary message may be removed or hidden.

In operation S1521, the device 1000 may group a plurality of other users and display messages received from the grouped other users as a single user group. The device 1000 may display, in the secondary chat window 3000, the messages received from the grouped other users together with an identification value indicating the user group. The device 1000 may generate a plurality of user groups based on at least one criterion. Other users may belong to the plurality of user groups.

An identification value of a user group may include an image and/or a text. In addition, the identification value of the user group may be an identification value randomly generated by the device 1000, an identification value generated based on identification values of a plurality of other users belonging to the user group, or an identification value input by the user but is not limited thereto. The identification value may be unique to the user group that the value is assigned to

In operation S1531, the device 1000 may display a summary message for each of the other users or user groups.
