## Background
BACKGROUND
The present disclosure relates to social networks and more specifically, to methods, systems and computer program products for providing search engine analytics and optimization for media content in social networks.
Recently, social networks have become an increasingly popular way for people to communicate with each other. One common use of social networks is for users to post media content items, such as pictures and videos, for others to see. In many cases the users may choose to associate one or more topics with the media content that they post. For example, users may associate one or more hashtags with a piece of content that they post. Users of the social network are able to search the social network for media content items that are related to various topics by searching for specific topics/tags.
One drawback to the current searching functions of social networks is that the results are presented based on the recency of when they were posted and the results are not ranked or filtered by their relevance to the topic searched. Currently, a user can associate any topic with a content item that they post, whether or not the content item is related to the topic. As a result, sometimes not all content items are related to the topics that users associated it with. This creates a problem for users who would like to search for content items related to a certain topic/tag in a social network.
SUMMARY
In accordance with an embodiment, a method for operating a search engine for media content in a social network is provided. The method includes receiving a query for media content related to a topic from a user, identifying a plurality of content items associated with the topic, and determining a quality score for each of the plurality of content items, wherein the quality score is an indication of a correlation between each of the plurality of the content item and the topic. The method also includes providing a subset of the plurality of content items to the user, wherein the subset is selected based on the quality score and updating the quality score of one or more content items in the subset based on a behavior of the user in viewing the subset of the plurality of content items.
In accordance with another embodiment, a system for searching a social network for media content includes a processor in communication with one or more types of memory. The processor is configured to receive a query for media content related to a topic from a user, identify a plurality of content items associated with the topic, and determine a quality score for each of the plurality of content items, wherein the quality score is an indication of a correlation between each of the plurality of the content item and the topic. The processor is also configured to provide a subset of the plurality of content items to the user, wherein the subset is selected based on the quality score and update the quality score of one or more content items in the subset based on a behavior of the user in viewing the subset of the plurality of content items.
In accordance with a further embodiment, a computer program product for operating a search engine for media content in a social network includes a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. The method includes receiving a query for media content related to a topic from a user, identifying a plurality of content items associated with the topic, and determining a quality score for each of the plurality of content items, wherein the quality score is an indication of a correlation between each of the plurality of the content item and the topic. The method also includes providing a subset of the plurality of content items to the user, wherein the subset is selected based on the quality score and updating the quality score of one or more content items in the subset based on a behavior of the user in viewing the subset of the plurality of content items.

DETAILED DESCRIPTION
In accordance with exemplary embodiments of the disclosure, methods, systems and computer program products for operating a search engine for media content in a social network are provided. In exemplary embodiments, content providers upload media content to the social network and associate one or more topics with the media content. Media content may include, but is not limited to, photos, videos, or music files. In exemplary embodiments, the search engine of the social network is configured to create a quality score that is used to track a correlation between piece of media content and each associated topic. The quality score can be based on feedback regarding the correlation between each topic and a piece of associated media content that is received from users of the social network or from metrics of how users of the social network interact with the media content and the associated topic. In exemplary embodiments, the search engine of the social network utilizes the quality score to rank the search results that will be provided when a user of the social network searches for media content that is associated with a topic.
Referring to FIG. 1, there is shown an embodiment of a processing system 100 for implementing the teachings herein. In this embodiment, the system 100 has one or more central processing units (processors) 101a, 101b, 101c, etc. (collectively or generically referred to as processor(s) 101). In one embodiment, each processor 101 may include a reduced instruction set computer (RISC) microprocessor. Processors 101 are coupled to system memory 114 and various other components via a system bus 113. Read only memory (ROM) 102 is coupled to the system bus 113 and may include a basic input/output system (BIOS), which controls certain basic functions of system 100.
FIG. 1 further depicts an input/output (I/O) adapter 107 and a network adapter 106 coupled to the system bus 113. I/O adapter 107 may be a small computer system interface (SCSI) adapter that communicates with a hard disk 103 and/or tape storage drive 105 or any other similar component. I/O adapter 107, hard disk 103, and tape storage device 105 are collectively referred to herein as mass storage 104. Operating system 120 for execution on the processing system 100 may be stored in mass storage 104. A network adapter 106 interconnects bus 113 with an outside network 116 enabling data processing system 100 to communicate with other such systems. A screen (e.g., a display monitor) 115 is connected to system bus 113 by display adaptor 112, which may include a graphics adapter to improve the performance of graphics intensive applications and a video controller. In one embodiment, adapters 107, 106, and 112 may be connected to one or more I/O busses that are connected to system bus 113 via an intermediate bus bridge (not shown). Suitable I/O buses for connecting peripheral devices such as hard disk controllers, network adapters, and graphics adapters typically include common protocols, such as the Peripheral Component Interconnect (PCI). Additional input/output devices are shown as connected to system bus 113 via user interface adapter 108 and display adapter 112. A keyboard 109, mouse 110, and speaker 111 all interconnected to bus 113 via user interface adapter 108, which may include, for example, a Super I/O chip integrating multiple device adapters into a single integrated circuit.
In exemplary embodiments, the processing system 100 includes a graphics processing unit 130. Graphics processing unit 130 is a specialized electronic circuit designed to manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display. In general, graphics processing unit 130 is very efficient at manipulating computer graphics and image processing, and has a highly parallel structure that makes it more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel.
Thus, as configured in FIG. 1, the system 100 includes processing capability in the form of processors 101, storage capability including system memory 114 and mass storage 104, input means such as keyboard 109 and mouse 110, and output capability including speaker 111 and display 115. In one embodiment, a portion of system memory 114 and mass storage 104 collectively store an operating system such as the AIX® operating system from IBM Corporation to coordinate the functions of the various components shown in FIG. 1. The system 100 may be, but is not limited to, a mainframe computer, a desktop computer, a laptop computer, a mobile phone, a wireless tablet or the like.
Referring now to FIG. 2, a system 200 including a social network 210 in accordance with an embodiment is illustrated. As illustrated, the system 200 includes a social network 210, a content provider 204 and a user 202. The social network 210 includes a content database 214 configured to store content received from the content providers 204 along with associated topics or tags. The social network 210 also includes a search engine 212 configured to receive a query including a topic from a user 202 and to responsively search the content database 214 for content associated with the topic.
In exemplary embodiments, the search engine 212 of the social network 210 is configured to create a quality score that is used to track a correlation between each topic and a piece of associated content. The quality score is stored in the content database 214 and can be based on feedback regarding the correlation between each topic and a piece of associated content that is input from users 202 of the social network 210 or from metrics of how users 202 of the social network 210 interact with the content and the associated topic. In exemplary embodiments, the search engine 212 of the social network 212 utilizes the quality score in ranking the search results that will be provided when a user 202 of the social network 210 searches for media content that is associated with a topic.
In exemplary embodiments, the search engine 212 of the social network 210 is configured to monitor a behavior of the users 202 of the social network 210 and to capture information that is indicative of the relevancy of content items to the associated topics. For example, upon receiving a query from a user 202 for topic A, the search engine 212 provides a list of content items. The search engine 212 can then monitor the behavior of the user 204 with respect to the content items provided and can extract relevancy information from the user's behavior. For example, if a user 202 spends more time viewing a particular content item, expresses liking a particular content item, writes a comment relating to a particular content item, or follows a content provider 204 of a particular content item it is a good indication that the content item is relevant to the searched topic. The search engine 212 can monitor the interaction of the user 202 with the content items provided and can use the interaction information to create and/or modify the quality score of the content items. The quality score of the content items can then be used by the search engine in determining how to rank the search results for new queries.
In exemplary embodiments, the search engine 212 can also create and/or update the quality score based on explicit feedback regarding the correlation between topics and a piece of associated content that is received from a user 202 of the social network 210. For example, upon receiving a query from a user 202 for topic A, the search engine 212 provides a list of content items. The search engine 212 can then provide the user 202 with a user interface option to indicate a positive correlation between the searched topic and the content item (e.g., the content item is related to the searched topic) and/or a negative correlation between the searched topic and the content item (e.g., the content item is not related to the searched topic.
In exemplary embodiments, the search engine of the social network is configured to use a ranking algorithm to sort the search results provided to a user in response to a query. The ranking algorithm may use a combination of the quality score, which represents the relevancy of the searched topic to the content times, and a time associated with the content items, such as when the content was posted, to rank the content items for displaying to the user. In another embodiment, the ranking algorithm may only use the quality score to rank the content items for displaying to the user. In another embodiment, positive or negative feedback of a content from a plurality of users who searched on the same topic can contribute to the calculation of a quality score.
In exemplary embodiments, if a content item has a high percentage of negative feedback explicitly expressed by users compared to the positive feedback (or the percentage is below a certain threshold), the content item may be included in a mismatch topic list. In addition, content items that are identified as belong to the mismatch topic list may have the improperly associated topic removed automatically or by social network teams after review.
Referring now to FIG. 3, a user interface 300 for allowing a user to indicate a correlation between the searched topic and content items in a social network in accordance with an exemplary embodiment is provided. As illustrated, the user interface 300 displays a plurality of content items 302 that are related to a search topic 304. The user interface 300 includes a plurality of user controls that include, but are not limited to, a back button 308, a home button 310, a favorite button 312, a like button 314, a relevant button 316 and a not relevant button 318. In exemplary embodiments, the user can select the like button 314 to express his or her liking to the media content. The user can select the favorite button 312 to express the media content is one of his or her favorite and enable the system to mark and store the media content in his or her favorite list. The user can select the relevant button 316 or the not relevant button 318 to express his or her opinion about the relevancy of the media content with respect to the searched topic. In exemplary embodiments, after a user selects one or the favorite button 312, the relevant button 314 and the not relevant button 316, a selection box 306 is overlaid on each content item 302 and allows a user to select the content items 302 that correspond to the selected category (favorite, relevant, not relevant). As will be appreciated by those of ordinary skill in the art, a similar user interface can be used for the viewing of a single content item as well. In addition, when viewing content items that have multiple associated topics, the user interface can allow the user to indicate whether the content item is relevant or not relevant to each of the separate topics.
In exemplary embodiment, the search engine of the social network may track the behavior of a user of the social network to create and store a topic relationship database. For example, if a user searches for a first topic, selects an image from the search results, and then from the selected image selects another associated topic, it may be used as an indication that both topics are related. Accordingly, the topics can be stored as related in the topic relationship database. The topic relationship database can then be used by the search engine to determine what content items may be relevant to a searched topic.
In one example, a user searches for a topic of “chicken” and selects an image from the set of results. Next, the user clicks on a topic of “salad” from the selected image, which instructs the search engine to perform a search for the topic “salad.” In this example, a linkage between chicken topic and salad topic is created and stored in the topic relationship database. In exemplary embodiments, the search engine may be configured to look up a search topic received from a user in the topic relationship database and if the user requests a repeated search, content items that have the requested topic and also have linked topics may be presented higher in the search results. In exemplary embodiments, the topic relationship database can be used track both individual topic linkages as well as social network wide topic linkages that are aggregated from a plurality of individual users.
In many cases, malicious content providers may seek to have their posted content viewed as often as possible and may associate irrelevant, but highly popular, topics with content that they post to the social network. In exemplary embodiments, the search engine of the social network may also track the behavior of the content providers and may adjust the quality score of the content items posted by the content providers based on the history of the content provider. In exemplary embodiments, the quality score of an association between a content item posted by a content provider and an associated topic may default to a historical quality score for the content provider based on calculated quality scores for the items previously posted by the content provider. In addition, the quality score of a score of an association between a content item posted by a content provider and an associated topic may be based on a length of time the content provider has been a member of the social network or a number of posts the content provider has made to the social network. For example, new content providers using the social network may have a maximum quality score that increases as their use of the social network increases and the relevancy of the content they posted with respect to the associated topics or tags they defined for the content. Such a maximum quality score for new users can serve to reduce the problem of individuals creating new accounts for a social network and posting content items and associating them with irrelevant and popular topics.
Referring now to FIG. 4, a flow diagram of a method 400 for operating a search engine for media content in a social network in accordance with an exemplary embodiment is shown. As shown at block 402, the method 400 includes receiving a query for media content related to a topic from a user. Next, the method 400 includes identifying a plurality of content items associated with the topic, as shown at block 404. The method 400 also includes determining a quality score for each of the plurality of content items, as shown at block 406. In exemplary embodiments, the quality score is an indication of the correlation between the content item and the topic. Next, as shown at block 408, the method 400 includes providing a subset of the plurality of content items to the users, wherein the subset is selected based on the quality score.
In one embodiment, the subset may include content items that have a quality score above a threshold level. In exemplary embodiments, the content items of the subset may be provided to the user in an order that is determined based on their associated quality score and based on a timestamp associated with the content items. For example, the subset of content items may be selected to include only content items that have a quality score of above 80 and may be presented to the user in an order based on a timestamp associated with the content items. In another embodiment, the subset may include a predetermined number of content items that have the highest quality scores. In exemplary embodiments, the content items of the subset may be provided to the user in an order that is determined based on their relative associated quality scores, i.e., the highest quality score items are displayed first. In exemplary embodiments, the user may determine, and save in their user preferences, what metrics are used in selecting the members of the subset and what metrics are used to order the presentation of the content items.
Continuing with reference to FIG. 4, as shown at block 410, the method 400 includes updating the quality score of one or more content items in the subset based on a behavior of the user in viewing the subset of the plurality of content items. In one embodiment, the behavior of the user in viewing the subset of the plurality of content items includes receiving feedback from the user that one or more content items in the subset is relevant to the topic and/or that one or more content items in the subset is not relevant to the topic. In another embodiment, the behavior of the user in viewing the subset of the plurality of content items includes a user liking one or more content items in the subset. In a further embodiment, the behavior of the user in viewing the subset of the plurality of content items includes an amount of time that a user spends looking at one or more content items in the subset. In yet another embodiment, the behavior of the user in viewing the subset of the plurality of content items includes a user following a content provider that posted one or more content items in the subset.
