Patent Application
20240135834
The present disclosure generally relates to data processing techniques. More specifically, the present disclosure relates to methods and systems for enhancing the quality of user-generated content for presentation via a question-and-answer service by presenting topic-specific biographical information about a user when presenting certain content elements related to the user.
Many on-line or web-based applications and services rely partially, and in some cases almost entirely, on user-generated content—that is, content generated by the end-users of the particular application or service. The success of such applications and services is heavily dependent upon the ability to attract and retain users who are willing to participate by generating content that is to be shared with other users. One particular type of application or service for which this holds true is an on-line question-and-answer service. In general, a question-and-answer service is a service that allows its end-users to post questions, post answers to questions, or simply browse the questions and answers that others have posted.
One of the ways that a user can assess the quality (e.g., accuracy, truthfulness, trustworthiness, etc.) of information, such as an answer that has been provided to a particular question, is to assess the source of the information. However, many question-and-answer services provide little more than the name of a person who has provided an answer to a question. This limits a user's ability to gain any insight into the quality of the information provided with an answer, particularly when the user who provided the answer is unknown to the user viewing the answer. A question-and-service may provide a link to a user's profile page, allowing a user browsing a particular answer to retrieve biographical information about a user who provided the answer. However, this generally requires that a user browsing an answer leave the current web page displaying the answer and load a new web page with the biographical information of the user who provided the answer. In addition, such an approach can be burdensome to the browsing user because it requires the user to wade through the entire profile of the user who provided the answer, and much of the profile may be irrelevant for purposes of assessing the quality of the answer.
Some embodiments of the invention are illustrated by way of example, and not limitation, in the figures of the accompanying drawings, in which:
Methods and systems for obtaining and displaying topic-specific biographical information about a user of a question-and-answer service are described. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of different embodiments of the present invention. It will be evident, however, to one skilled in the art, that the present invention may be practiced without these specific details.
A question-and-answer application or service provides an on-line forum where users can post questions, post answers to questions, or simply search for and review questions and answers that others have posted. As such, a question-and-answer application is an information repository of user-generated content that is organized and presented in a relatively simple and intuitive manner. For purposes of the present disclosure, an individual web page showing all questions related to a particular topic may be referred to as a topic page, whereas a web page showing an individual question and any associated answers to the question, will generally be referred to herein as a question page. Finally, a page that shows profile information about a particular user is referred to herein as a user profile page, or simply, a profile.
With some question-and-answer services, content is structured to a certain extent, by explicitly assigning questions and/or answers to various topics. For example, to aid in the overall organization and presentation of information, a question might be assigned to one or more topics representing, for example, a subject matter to which the question relates. Take for example the question, “What is the population of San Francisco?” This question may be assigned to the topic, “San Francisco.” With some embodiments, as users post questions for others to answer, users can designate each question as being related to one or more existing topics, or users can create and designate new topics. In some embodiments, any user may be free to assign a content item, such as a question or a biographical statement of a user, to a particular topic. Alternatively, in some embodiments, only designated users or administrators may have the required permissions or assigned roles necessary for assigning questions to particular topics. For purposes of the present disclosure, a content item (e.g., a question or a biographical statement) is said to have been assigned to a topic when the topic has been explicitly designated by a user or administrator.
The extent to which the content of a question-and-service is structured may vary considerably from one implementation to the next. For instance, with some question-and-answer services, questions and answers may not be explicitly assigned to topics. However, analysis of the text of a question or answer, as well as analysis of certain meta-data associated with a question or answer, may allow the question-and-answer service to infer one or more topics with which a question or answer is associated. For example, the question, “What is a good introductory book for learning Java programming?” might be associated with the topic, “Java (computer programming)” as a result of the question including the word, “Java.” Similarly, analysis of the text and meta-data associated with one or more answers to a question may allow the question-and-answer service to infer one or more topics with which the question is associated. With some embodiments of the invention, the question-and-answer service may perform textual analysis of the text of certain content items (e.g., questions and biographical statement in particular) to determine the topics with which the content items are associated. For purposes of the present disclosure, a content item is said to be associated with a topic, when the topic is inferred from analyzing the text of the content item and any meta-data associated with the content item.
Consistent with embodiments of the invention, a question-and-answer service presents topic-specific biographical information about a user when presenting web pages including certain content elements, for example, such as an answer to a question that has been provided by the user. For example, a question page generally displays the text of a question that has been posted by a user along with a list of user-provided answers to the question. To enable users who are viewing the answers to assess the source and quality of the answers, the name of each person who provided an answer may be displayed next to his or her answer. In addition to displaying the user's name next to his or her answer, the question-and-answer service selects a particular portion of the user's biographical information to display in connection with (e.g., next to, or, near) the user's answer. The biographical information of the user is generally selected for being relevant with respect to a topic to which the question and answer relate.
For example, if a question on a question page has been explicitly assigned to the topic “Basketball”, when a user provides an answer to the question, some portion of the user's biographical information relevant to that user's experience with the topic “Basketball” is selected and displayed next to the user's answer. Similarly, if a question on a question page has been explicitly assigned to the topic “Venture Capital”, when the user provides an answer to the question, some portion of the user's biographical information relevant to the user's experience with the topic “Venture Capital” will be displayed in connection with his or her answer. With some embodiments, the question-and-answer service may infer one or more topics with which a question is associated, based on an analysis of the text of a question, an analysis of the text of one or more answers to the question, and/or the analysis of some meta-data associated with a question and/or answers. Displaying topic-specific biographical information of a user when presenting various content elements (e.g., such as a question provided by a user) not only allows users who are browsing questions and answers to assess the trustworthiness of an answer based on relevant information concerning the provider of the answer, but it also eliminates the need for a user who answers a lot of questions to provide biographical information about him or herself with each and every question that the user answers.
Consistent with some embodiments of the invention, the topic-specific biographical information for a user may be displayed in a variety of contexts. For example, a topic-specific biographical statement may be displayed with an answer provided by a user, when that answer is displayed in a question page. In such a scenario, the particular topic-specific biographical statement will be selected for its relevance or relationship to the topic of the question on the question page. So, for example, if the question is assigned to the topic, “Basketball”, the biographical statement related to a user's experience with the topic “Basketball” will be displayed next to his or her answer. Similarly, a topic-specific biographical statement may be displayed along with a comment that a user has provided. Here again, the biographical statement will be selected for its relevance or relationship with respect to the topic of the question to which the comment relates.
Topic-specific biographical information may also be displayed in other scenarios as well. For instance, in certain contexts, a web page may include information about the particular users who are following a question, or a topic. For instance, a question page may include information about the particular users who are following the question that is shown on that question page. In addition to showing the individual users who are following the question, topic-specific biographical information about each user following the question may be displayed as well. This allows a user browsing a question page to identify other users who may have expertise concerning certain topics. Accordingly, if a user browsing a question page identifies another user who, based on his or her biographical information, seems interesting to the browsing user, the browsing user can elect to follow that user. Similarly, a topic page may present information about the various users who are following a topic. In addition to showing who (i.e., which users) are following the topic, the topic page may display topic-specific biographical information about the users who are following the topic. A user who is browsing a topic page because of an interest in the topic may elect to follow one or more of the other users who are also following the topic of the topic page. As such, the topic-specific biographical information that is displayed about a user not only allows a browsing user to assess the quality of any information that is provided by a user, but also serves a discovery purpose by enabling browsing users to discover other potential sources of relevant information about a particular topic. Other aspects and advantages of the inventive subject matter described herein will be readily apparent to skilled artisans from the description of the figures that follows.
The concept of “following” may be thought of as a unilateral relationship, because it can be achieved at the desire of only one user. This is in contrast to the concept of two users being “connected” (e.g., in a social networking context), which typically implies a personal relationship between the users. Two users may be “connected” when each user is following the other—a bilaterally defined relationship. In some embodiments of the invention, the enabled features and interactions that the users are allowed to have with one another may be controlled to some extent by the type of relationship that exists between users, as that relationship is defined by the question-and-answer service, or some externally-hosted social network service. For instance, with some embodiments, a user may be able to provide or suggest a topic-specific biographical statement for another user when the two users are “connected”—that is, each user is following the other. Accordingly, at least with some embodiments, this feature is enabled with respect to two users only when a system-defined relationship exists between the two users.
As illustrated in
In some embodiments of the invention, notifications may be communicated to a user by simply including the relevant content in a landing page or data feed displayed to the user. For example, when a user first provides his or her authentication information (e.g., username/password), the user may be presented with a personalized home page or landing page with content that is customized for the user. This content may be selected to include information regarding the users, topics and questions that the particular user is following. Additionally, in some embodiments, notifications may be communicated in near real-time to a user via any number of messaging mechanisms, to include a real-time dynamic data feed (e.g., web page) updates, email, SMS or text messages, instant messages, and others. In some embodiments, a user may elect to be notified of certain activities or events on a per-question, per-topic or per-user basis. For instance, a user may elect to receive a notification when a new answer is posted to a particular question that the user is following. When a first user suggests a topic-specific biographical statement for a second user, a notification message may appear to notify the second user about the topic-specific biographical statement that has been suggested by the first user.
Referring again to
In addition to a wiki summary 18, a question 16 is associated with one or more answers 20. For instance, after a user posts a question, other users of the application are able to provide answers to the question. In some embodiments of the invention, any user is allowed to post an answer to a particular question. As such, a question may be associated with or have multiple answers. In some embodiments, both questions 16 and answers 20 may have comments. For instance, a user may provide a textual comment that is associated with a question 16 or an answer 20. A comment associated with an answer, for example, could provide some clarification about a particular answer, or some aspect of the answer. Other users can then view the comments when viewing the question and/or answers.
In some embodiments of the invention, an answer 20 has or is associated with votes 24. For example, users can vote up or vote down a particular answer based on whether the user finds the answer helpful in view of the particular question. For instance, if a user believes that a particular answer to a question is a good answer, the user can select a button or other graphical user interface element to vote for the answer. Similarly, if a user believes that a particular answer is not helpful in light of the question, the user can vote down the answer, for example, by simply selecting a button or other graphical user interface element to indicate that the answer is not helpful. In some embodiments, the number of votes for and against an answer are used as inputs to an algorithm that determines how answers are to be displayed when presented to a user. For example, the votes for and against an answer may simply be tallied, such that a vote for the answer offsets a vote against the answer, and the answers with the highest vote tallies are displayed in the most prominent positions—typically, at the top of a list of relevant answers.
By providing a forum that includes questions, answers, comments and votes, the question-and-answer application encourages meaningful discussion about a whole host of subject matters, in part, by enabling users to interact with the application in a variety of ways. For instance, some users may desire an entirely passive experience, and can therefore simply browse for, and read, questions and answers on topics of interest. Some users may desire an experience including a moderate level of participation, and as such, these users can vote up or down various answers on topics of interest, and possibly provide commentary. Others may desire to participate more actively, and will elect to post questions and answers to questions.
As illustrated in
The question-and-answer application logic 30 is shown in
The messaging and notification logic 48 operates in conjunction with the content posting logic 44 and the editor 46 to facilitate the generation and communication of messages and notifications. For instance, if a first user provides a suggested biographical statement for a second user, the second user will receive a notification or message, delivered by the messaging and notification logic 48, which notifies the second user of the suggested biographical statement provided by the first user.
Consistent with some embodiments, the external data module 45 operates to query one or more external data sources 49 for relevant biographical information about users of the question-and-answer service. For instance, the external data module 45 may utilize one or more application programming interfaces (APIs) to connect with an external data source having biographical information about users of the question-and-answer service. The external data source may be a social or business network service, an email service, or some other web-based service. In some embodiments, the external data module 45 queries one or more external data sources 49 for relevant biographical information, and then stores any retrieved information in a database 42. Accordingly, this information can be used when displaying topic-specific biographical information about users. In some embodiments, the external data module 45 may retrieve data from an external data source in real-time, as it is preparing a page to be displayed for a user. Depending upon the nature of the external data source, a user's permission (e.g., password) may or may not be required to access the external data source 49. The retrieved data may be automatically associated with one or more topics based on the structure and source of the data. Alternatively, the question-and-answer service may prompt a user to assign some retrieved biographical data to one or more topics.
With some embodiments, the question-and-answer service includes a location based services module 47. The location based services module 47 analyzes location information of users, and in some instances, may serve as a source of topic-specific biographical information about a user. For instance, many questions that are posted to the question-and-answer service have a geographical component. For example, the question “What are the five best restaurants in San Francisco?” is a question that relates to the city of San Francisco. Accordingly, if a user resides in the city of San Francisco, the user is more likely able to provide a quality answer to the question than is a user who lives in Florida, for example. Therefore, the location based services module may infer a user's location using location information, such as the Internet Protocol (IP) address of a user's computing device, and then display this location information with an item of content, such as a user's answer. With some embodiments, the location based services module 47 may leverage an external data source for various types of location information. Of course, the application logic 30 may include a number of other logical components to perform a variety of other tasks and functions beyond the immediate scope of the present inventive subject matter. As such, to avoid obscuring the inventive subject matter in unnecessary detail, these various functional components have not been included in
In some embodiments, some of the various functional components of the question-and-answer application, including some of the various software modules, may be distributed across several server computers, providing application reliability and scalability. For instance, as illustrated in
Consistent with some embodiments, the question-and-answer service is a stand-alone service accessible via its own unique address (e.g., URL or URI). With some embodiments, the stand-alone service may leverage its own social layer, or a social layer provided by an externally-hosted social network service. Accordingly, various relationships between users, as determined or defined by the question-and-answer service or an externally-hosted social network service, may be utilized to customize the functionality and features of the question-and-answer service. For example, certain interactions between users may be controlled based on the relationships that exist between the users, as those relationships are defined by an externally-hosted social network service. Alternatively, with some embodiments, the question-and-answer service may be one of several applications or services that are associated with, and provided by, a social network service. For instance, the question-and-answer service may be accessible via the same address or domain by which users access a social network service, such that the question-and-answer service is hosted by the same entity providing the social network service.
As illustrated in
Next, at method operation 62, the question-and-answer service identifies an answer to the question. For example, the question-and-answer service may query a database table to select one or more answers to the question, where each answer was previously posted to the question-and-answer service by a user of the question-and-answer service. At method operation 64, the question-and-answer service selects a topic-specific biographical statement to be presented on the question page next to or near the name of the user who provided the answer to the question. Finally, at method operation 66, the question page is presented or served to the requesting client device, such that the question page includes the text of the question, at least one answer to the question, the name of the user who provided the answer to the question, and the selected topic-specific biographical statement of the user who provided the answer.
With some embodiments, selecting a topic-specific biographical statement of a user to be displayed with an answer to a question is a simple matter of identifying a biographical statement that has been explicitly assigned to a particular topic, such that the information is stored in a database in some manner that associates the biographical statement with one or more topics. However, with some embodiments, a user's biographical information may not be explicitly assigned to topics. As such, a user's biographical information and any available associated meta-data may be analyzed by the question-and-answer service to identify portions of the user's biographical information that are related to the topic with which the question is associated. This may occur in real-time, as a page request is being processed, or the analysis may occur prior to processing a page request.
In addition to displaying topic-specific biographical information about a user when showing an answer provided by the user, the question-and-answer service may display topic-specific biographical information about users in a number of other contexts as well. For instance,
Next, at method operation 82, the question-and-answer service selects topic-specific biographical information of a user who is following the question. The topic-specific biographical information is identified and/or selected for its relevance to, or relationship with, at least one topic to which the question being followed is assigned, or with which the question being followed is associated. For instance, with some embodiments, a user may explicitly assign a question to a topic. In other embodiments, the question-and-answer service may analyze the question and determine a topic with which the question is associated. Finally, at method operation 84, the question-and-answer service presents a user interface (e.g., a web page) showing the question that is being followed by a user, the information identifying the user that is following the question, and the selected biographical information about the user who is following the question. For example, if a user is following a question assigned to or associated with the topic, “Ice Hockey”, a portion of the user's biographical information relating to his or her experience with the topic, “Ice Hockey” will be selected for presentation next to or near the information that indicates the user is following the question about ice hockey. This allows other users to quickly assess the user's biographical information and make a determination about whether the user whose biographical information is displayed might be worth following.
In yet another example,
Next, at method operation 88, the question-and-answer service selects topic-specific biographical information of the user who is following the topic. The topic-specific biographical information is selected for its relevance to the topic that the user is following. In some embodiments, the question-and-answer service may query an external data source in real-time for topic-specific biographical information of a user. Finally, at method operation 90, the question-and-answer service presents a user interface (e.g., a web page) showing the topic that is being followed by the user, the information identifying the user that is following the topic, and the biographical information about the user who is following the topic.
In many instances, a particular content item (e.g., a question) may be assigned to, or associated with, more than one topic. Accordingly, various algorithms and factors may be utilized in determining the specific biographical statement of a user that is displayed for the user, when the biographical statement is being presented in connection with a content item that has been assigned to, or is associated with, multiple topics. For example, when a content item, such as a question, has been assigned to several topics, selecting a biographical statement for a user to be presented may involve analyzing the overall amount of user activity associated with the respective topics, and choosing the biographical statement that is associated with the topic that has the most user activity, or the most recent user activity. Alternatively, with some embodiments, preference may be given to a topic that has the least number of followers, as compared with other topics assigned to, or associated with, the question. For instance, consider an example for which a particular question is assigned to, or associated with, the topics, “Sports” and “WNBA Basketball.” In this example, the number of followers for the topic “Sports” is likely to be greater than the number of followers for the topic, “WNBA Basketball.” Therefore, by selecting the topic with the fewest number of followers, the topic that most closely relates to the question is selected—in this example, “WNBA Basketball.” Of course, with some embodiments, the algorithm for selecting a biographical statement of a user to be displayed with a question assigned to, or associated with, more than one topic, may involve a combination of weighted factors.
With some embodiments, topics may be organized in a hierarchical structure, such that topics have one or more levels of sub-topics. Accordingly, when selecting biographical information of a user to be presented, the biographical statement may be selected because it is assigned to, or associated with, a sub-topic of a topic to which a particular content item is assigned. For example, if a question has been assigned to the topics, “Sports”, “NBA Basketball” and “NBA Basketball Players,” assuming the topic, “NBA Basketball Player” is the lowest level sub-topic, any biographical information of a user assigned to this lower-level sub-topic would take preference over biographical information assigned to one of the higher level topics.
With some embodiments of the invention, there are a variety of ways that a topic-specific biographical statement might be added to a user's profile. For instance, from a user's personal profile page, a user may invoke a topic-specific biographical information editor to add, delete and edit biographical statements associated with any one or more of the topics that the user is following. On a topic page for a particular topic, a user can enter a topic-specific biographical statement for the topic, regardless of whether the user is following the topic. With some embodiments, a user can add a topic-specific biographical statement for another user at that user's profile page, or on other pages. With some embodiments, a user may specify a particular biographical statement for display on a per-question basis, or, for display with the user's name in some other particular context. As described in connection with the flow diagram of
For example, referring now to
As illustrated in
In this example user interface, beneath the question 104 are two answers 112 and 114 provided by two different users. Associated with each answer is a name of the user who posted the answer, along with a brief topic-specific biographical statement about each user who provided an answer. For example, the first answer 112 was posted by the user, John Smith, who, according to the topic-specific biographical statement 113, was a “Former Disneyland Staff Member.” The second answer 114 was posted by Kate Johansen who, according to her topic-specific biographical statement, is a “thrill ride seeker and parent of five.” Beneath each respective answer are buttons or links that enable a user to add a comment about an answer, or indicate that an answer was helpful or not helpful. In addition, to the left of each answer are two arrows for use in voting. For example, the arrow buttons (up and down) for the answer posted by John Smith are shown with reference number 116. The votes for and against an answer may be used in an algorithm that determines the order in which answers to a particular question are presented.

The example user interface shown in
The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented modules that operate to perform one or more operations or functions. The modules or logical components referred to herein may, in some example embodiments, comprise processor-implemented modules or logic.
Similarly, the methods described herein may be at least partially processor-implemented. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented modules. The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processor or processors may be located in a single location (e.g., within a home environment, an office environment or as a server farm), while in other embodiments the processors may be distributed across a number of locations.
The one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., Application Program Interfaces (APIs).)
The example computer system 1500 includes a processor 1502 (e.g., a central processing unit (CPU), a graphics processing unit (GPU) or both), a main memory 1501 and a static memory 1506, which communicate with each other via a bus 1508. The computer system 1500 may further include a display unit 1510, an alphanumeric input device 1517 (e.g., a keyboard), and a user interface (UI) navigation device 1511 (e.g., a mouse). In one embodiment, the display, input device and cursor control device are a touch screen display. The computer system 1500 may additionally include a storage device (e.g., drive unit 1516), a signal generation device 1518 (e.g., a speaker), a network interface device 1520, and one or more sensors 1521, such as a global positioning system sensor, compass, accelerometer, or other sensor.
The drive unit 1516 includes a machine-readable medium 1522 on which is stored one or more sets of instructions and data structures (e.g., software 1523) embodying or utilized by any one or more of the methodologies or functions described herein. The software 1523 may also reside, completely or at least partially, within the main memory 1501 and/or within the processor 1502 during execution thereof by the computer system 1500, the main memory 1501 and the processor 1502 also constituting machine-readable media.
While the machine-readable medium 1522 is illustrated in an example embodiment to be a single medium, the term “machine-readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more instructions. The term “machine-readable medium” shall also be taken to include any tangible medium that is capable of storing, encoding or carrying instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present invention, or that is capable of storing, encoding or carrying data structures utilized by or associated with such instructions. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, and optical and magnetic media. Specific examples of machine-readable media include non-volatile memory, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.
The software 1523 may further be transmitted or received over a communications network 1526 using a transmission medium via the network interface device 1520 utilizing any one of a number of well-known transfer protocols (e.g., HTTP). Examples of communication networks include a local area network (“LAN”), a wide area network (“WAN”), the Internet, mobile telephone networks, Plain Old Telephone (POTS) networks, and wireless data networks (e.g., Wi-Fi® and WiMax® networks). The term “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding or carrying instructions for execution by the machine, and includes digital or analog communications signals or other intangible medium to facilitate communication of such software.
Although an embodiment has been described with reference to specific example embodiments, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader spirit and scope of the invention. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense. The accompanying drawings that form a part hereof, show by way of illustration, and not of limitation, specific embodiments in which the subject matter may be practiced. The embodiments illustrated are described in sufficient detail to enable those skilled in the art to practice the teachings disclosed herein. Other embodiments may be utilized and derived therefrom, such that structural and logical substitutions and changes may be made without departing from the scope of this disclosure. This Detailed Description, therefore, is not to be taken in a limiting sense, and the scope of various embodiments is defined only by the appended claims, along with the full range of equivalents to which such claims are entitled.
