## Background
This application claims the benefit under 35 U.S.C. § 119(e) of the filing date of U.S. Patent Application No. 61/531,287, for Social Search, which was filed on Sep. 6, 2011, and which is incorporated here by reference.


BACKGROUND
This disclosure relates generally to searching using social network data.
Search engines identify resources (e.g., images, audio, video, Web pages, text, documents) that are relevant to a user's needs and present information about the resources in a manner that is useful to the user. Typically, a search engine returns a set of search results in response to a user submitted query. Such a search is transactional in that it attempts to locate content to satisfy a need.
Social networks permit users to post information about themselves and to communicate with other people, e.g., their friends, family, and co-workers. Some social networks permit users to specify friendships with other users. Additionally, social network users may write descriptions of their interests and disinterests (e.g., what they like or don't like), compose stories, describe their lives, etc.
SUMMARY
An example of a technique for performing a social search may include the following operations: receiving a request for search results; in response to the request, obtaining search results using one or more social engagement signals to identify content items, where the one or more social engagement signals are unspecified in the request; and providing the search results identifying content items to a computing device.
In the foregoing technique: the one or more social engagement signals for a content item may correspond to a number of times the content item has been shared in a social networking service; the one or more social engagement signals may correspond to a number of comments on the content item in a social networking service; the one or more social engagement signals may correspond to a length of the content item in a social networking service; the one or more social engagement signals may correspond to a composition of the content item in a social networking service; the one or more social engagement signals may correspond to a number of links in the content item in a social networking service; the one or more social engagement signals may correspond to a manner in which links were incorporated into the content item in a social networking service; the one or more social engagement signals may correspond to a pattern in which the content item of a social networking service has been shared; the one or more social engagement signals may correspond to a number of recommendations of the content item in a social networking service; or the one or more social engagement signals may correspond to a combination of the foregoing examples.
In the foregoing technique, key words may be absent from the request for search results. The search results may include content items that had been added to a corpus of content items of a social networking service by members of the social networking service.
Examples of operations that may be performed in the foregoing technique may include ranking the search results before providing the search results to the computing device. The search results may be ranked in accordance with weights associated with different ones of the social engagement signals. The search results may be ranked in accordance with information contained in a profile of a member of a social networking service.
Another example of a technique for performing a social search may include the following operations: searching for content through a social networking service using one or more social engagement signals, where the searching is performed by traversing an indexed cache of content to identify content items that correspond to social engagement signals, and where the social engagement signals are obtained from a storage medium of the social networking service; ranking content items obtained as a result of the searching, where the content items are ranked according to criteria, an example of which includes information available from a profile of a member of the social networking service; and outputting the ranked content to a computing device.
In the foregoing technique, the social engagement signals for a content item may correspond to one of, or two or more of, the following: a number of comments on the content item in the social networking service, a length of the content item in the social networking service, a composition of the content in the social networking service, a number of links in the content item in the social networking service, a manner in which links were incorporated into the content item in the social networking service, a pattern in which the content item in the social networking service has been shared, and a number of recommendations of the content item in the social networking service.
Advantages of the foregoing techniques may include providing, in response to a request, search results that are likely to be of interest to users. The search results may be obtained, and provided, absent key words in an input request for search results. Accordingly, a searcher may have access to search results that are of interest and for which they might not have otherwise searched.
All or part of the systems and techniques described herein may be implemented as a computer program product that includes instructions that are stored on one or more non-transitory machine-readable storage media, and that are executable on one or more data processing devices, e.g., computers. All or part of the systems and techniques described herein may be implemented as an apparatus, method, or electronic system that may include one or more processing devices and memory to store executable instructions to implement the stated functions.
The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION
Described herein are systems and methods for searching on a social network using social engagement signals. For example, an index associated with a social networking service may be searched using one or more signals that are selected to identify content items that may be of interest to users. The signals may be predefined and independent of (e.g., unrelated to) an instruction to perform a search. For example, in some implementations, these signals are not based on key words input to a search engine (e.g., the signals are unspecified in a request for search results). As a result, content that may be of interest to the user, e.g., “interesting content”, can be provided to a user, without the user actually having to provide a query (e.g., search terms for a text query, an image as an image query) for that content. The content may be from a corpus of the social networking service or from public sources, e.g., the Internet. Appropriate content that is available to a search engine (e.g., public and or authorized, private content) may be provided.
In an example implementation, a user may initiate a search for interesting content by providing a computer instruction through a user interface (e.g., by selecting an appropriate search option presented on a Web page). As noted above, the search can be initiated by the user without providing a search query. In response to the instruction, the user is presented with a number of search results by a search system.
In an example, a user initiates the search by clicking a Web button on a Web page maintained by a social networking service. In response, a search system associated with the social networking service identifies content by searching an index of social media content (which the user is authorized to access) and public content (e.g., Web sites) that have been interacted with (e.g., shared, commented-on, endorsed, etc.) by members of the social networking service. The search system searches the index by using social engagement signals associated with each resource (content item) represented in the index, where the social engagement signals may represent the number of times each of the respective resources has been interacted with by members of the social network, the types of interactions, the number of members who interacted, and the like. The resources which have been interacted with substantially according to the social engagement signals may be presented as a ranked listing of search results.
The process described above may be implemented in an appropriate network environment, with appropriate devices and computing equipment. An example of such an environment is described below.
FIG. 1 is a block diagram showing an example network environment on which the process described herein for searching a social network using social engagement signals may be implemented. In this regard, FIG. 1 shows an example network environment 100. The network environment 100 includes computing devices 102, 104, 106, 108, 110 that can each communicate with a first server system 112 and/or a second server system 114 over a network 111. Each of computing devices 102, 104, 106, 108, 110 has a respective user 122, 124, 126, 128, 130 associated therewith. Each of the first and second server systems 112, 114 includes a computing device 116 and a machine-readable repository, or database 118. Example environment 100 may include many thousands of Web sites, computing devices and servers, which are not shown.
The network 111 can include a large computer network, e.g., a local area network (LAN), wide area network (WAN), the Internet, a cellular network, or a combination thereof connecting a number of mobile computing devices, fixed computing devices, and server systems. The network(s) may provide for communications under various modes or protocols, e.g., Transmission Control Protocol/Internet Protocol (TCP/IP), Global System for Mobile communication (GSM) voice calls, Short Message Service (SMS), Enhanced Messaging Service (EMS), or Multimedia Messaging Service (MMS) messaging, Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Personal Digital Cellular (PDC), Wideband Code Division Multiple Access (WCDMA), CDMA2000, or General Packet Radio System (GPRS), among others. Communication may occur through a radio-frequency transceiver. In addition, short-range communication may occur, e.g., using a Bluetooth, WiFi, or other such transceiver.
Computing devices 102 to 110 enable respective users 122 to 130 to access and to view documents, e.g., Web pages included in Web sites. For example, user 122 of computing device 102 can view a Web page using a Web browser. The Web page can be provided to computing device(s) 102 to 110 by server system 112, server system 114 or another server system (not shown). In example environment 100, computing devices 102, 104, 106 are illustrated as desktop-type computing devices, computing device 108 is illustrated as a laptop-type computing device 108, and computing device 110 is illustrated as a mobile computing device. It is appreciated, however, that computing devices 102 to 110 can each include a type of computing device, examples of which include a desktop computer, a laptop computer, a handheld computer, a personal digital assistant (PDA), a cellular telephone, a network appliance, a camera, a smart phone, an enhanced general packet radio service (EGPRS) mobile phone, a media player, a navigation device, an email device, a game console, or a combination of two or more of these data processing devices or other appropriate data processing devices. In some implementations, a computing device can be included as part of a motor vehicle (e.g., an automobile, an emergency vehicle (e.g., fire truck, ambulance), a bus).
FIG. 2 is a diagram of an example portion of the network environment of FIG. 1. In this regard, FIG. 2 shows a portion 200 of example network environment 100. Network environment 100 includes a search system 212 that identifies resources 205 (e.g., Web pages, images, or news articles on the Internet) by crawling and indexing resources provided by content publishers on Web sites 204.
In FIG. 2, computing device 104 communicates with server system 112 to display a Web page 202 for accessing a social networking service. In this example, server system 112 stores a plurality of resources 204, 206, 208, each having an associated resource identifier (Resource ID). In this example, resources 204, 206, 208 correspond to different content available from the social networking service and from other public and private sources, e.g., public Web sites, social networking Web sites, picture hosting Web sites, and online e-mail providers. Owners of private content may not give permission to have their private content made available to others.
To view a Web page, user 124 can input or select a Resource ID using a browser that is executed on computing device 104. The Resource ID can include, for example, a uniform resource indicator (URI) and a uniform resource locator (URL). A request including the Resource ID is transmitted from computing device 104 to server system 112 over network 111. In response, the server system identifies the requested resource based on the Resource ID, and transmits the resource to computing device 104 over network 111. For example, the resource may be a Web page 202, through which a user may access a social networking service. The Web page may include a field 205 for inputting user account information, e.g., a username and password.
The social networking service may include a search system 212 that identifies resources by crawling and indexing those resources. In this regard, search system may include an indexing engine 213 that indexes resources (e.g., discussion topic by subject, discussion topics by tag, user profiles, social media posts, and the like), which may be found, e.g., in the corpus of the social networking service, e.g., a collection or repository of content, or on publicly-accessible Web sites. In some implementations, an owner of private content may opt-out of having their private content included in the search index. An index cache 214 stores the index information, and a ranking engine 215 (or other software) ranks the resources based on criteria, e.g., popularity. The search may be implemented, e.g., on server system 112 as shown, which may include multiple computers at multiple locations, or on other appropriate hardware. The indexed and, optionally, cached copies of the resources can be stored in an indexed cache 214. In response to an input, the search system can access indexed cache 214 to identify resources that are relevant to the input. Ranking engine 215 ranks the identified resources based, e.g., on popularity or other appropriate criteria.
FIG. 3 is a flowchart of an example method for identifying and retrieving search results determined by a search system to likely be interesting for users. In this regard, FIG. 3 shows an example process 300 for retrieving search results using social engagement signals. Process 300 may be performed, e.g., by engine 216 in server system 112. However, other appropriate hardware and/or software may be used to perform process 300.
Process 300 receives an instruction (302). The instruction may be received from a Web page of a user's computing device. For example, the user may select a button or other control or a link provided on the Web page. An example of such a button is button 402, which is on the Web page shown in FIG. 4. As described below, in response to receipt (302) of the instruction, process 300 performs a search of indexed resources using one or more social engagement signals. The user need not provide search terms in this case; rather, searching is performed independently of a user input (other than the instruction to perform the search itself). Examples of social engagement signals were provided above and are provided below.
Process 300 determines (304) that the received instruction is instructing to perform a search using social engagement signals. Process 300 may make this determination based on the content of the instruction. For example, such information may be included in the search instruction that indicates to search for content using the stored social engagement signals.
Following operation 304, process 300 retrieves one or more social engagement signals (306). To retrieve the social engagement signal(s), process 300 may access a data structure (e.g., a database or index) in which social engagement signals are stored. In some implementations, the data structure may be the search index. For example, a social engagement signal associated with a resource may be stored in the search index along with an identifier (ID) for that resource.
A social engagement signal is storable data that indicates how much interest users, e.g., members of a social networking service, have shown in a resource (for example, the probability that a user will engage with the resource). In some implementations, a social engagement signal can be a quantifiable value associated with a particular resource (e.g., a particular social media post or other similar social media content item) that is indicative of the interest of a community of users in the content item. In some implementations, a social engagement signal can correspond to the number of times a particular resource has been searched, shared, commented on, or recommended in a social networking service by members of the social networking service. For example, a resource that has been retrieved a number of times, in response to independent search queries in a social networking service by members of the social networking service, may be deemed to be of interest to members of the social networking service. For example, a resource that has been retrieved more than 10, 100, 1000, etc. times within a specified time period, e.g., one day, a week, a month, etc. by members of the social networking service may be considered to be of interest to members of the social networking service.
In some implementations, an identified pattern of searching, sharing, commenting, and/or recommending can be a social engagement signal. In this regard, if the number of comments associated with a particular resource by members of the social networking service has recently spiked (or is known to spike at certain times) (e.g., 10, 100 or 1000 times within, e.g., a day, a week, a month, etc.), process 300 may determine that the resource is likely to currently be of interest (or will likely be of interest in the future). For example, a resource containing content associated with a sporting event (e.g., blogs) may be commented on, shared, or recommended with greater frequency during, directly before, or directly after the event. As such, this resource may be deemed by the search system to be of interest to some users at these times.
Social engagement signals can be determined (and subsequently stored in a data structure) continuously or at predetermined intervals. Further, although a number of social engagement signals have been described, other suitable social engagement signals can also be used. Additionally, in some implementations, a combination of two or more social engagement signals can be used for identifying resources that are likely to be of interest to a user.
Referring back to FIG. 3, process 300 may search an appropriate data structure for instances of certain types of social engagement signals (or, e.g., for a specified combination of social engagement signals), associated with all types of resources or associated with specified types of resources, that provide the strongest indication of user engagement (e.g., the strongest social engagement signals, e.g., the largest numbers of comments on resources). For instance, the search engine can identify a predetermined number of the strongest social engagement signals (e.g., the ten strongest social engagement signals, e.g., the ten largest numbers of comments).
The strength of a social engagement signal that is associated with a particular resource can be used as an estimate of the resource's interest to users. The strength of a social engagement signal may be determined based on the value of the signal (e.g., the number of times a particular resource has been shared, commented on, or recommended) or it may the value of the signal itself.
Process 300 searches (308) a search index, e.g., indexed cache 214, to identify resources associated with the strongest social engagement signals. Process 300 may identify such resources by matching the retrieved social engagement signals to the respective resources to which they are associated (310).
Engine 216 may rank the identified resources (312). For example, engine 216 can score the resources based on the strength of one or more associated social engagement signals, which may be weighted with signal-specific weights. Engine 216 may rank a resource based on the scores. Engine 216 may rank a resource associated with a relatively strong social engagement signal higher than a resource associated with a relatively weak social engagement signal. In some implementations, engine 216 can rank the resources based on relevance of the resources to perceived interests of the user. For example, engine 216 can rank the resources in accordance with information contained in the user's profile (e.g., their perceived interests). For another example, engine 216 can optionally rank the resources in accordance with content of the resources. For example, a first Web page that includes several links may be determined to be of greater value than a second Web page that includes a single link, because the first Web page may provide more “link surfing” opportunities (link surfing may be considered the process of starting on one Web page and clicking on various hyperlinks to eventually finish on a different Web page that may, or may not, be predetermined). Further, a Web page that includes a number of relevant links incorporated in the text of an article or post may be determined to be of greater value than a Web page that lists a number of unrelated links in advertising space. For another example, a Web page including several videos may be determined by the search system to be of greater value than a Web page including a single video. Additionally, a Web page that includes several different types of content (e.g., text, still images, and vides) may be determined to be of greater value than a Web page that includes a single type of content (e.g., just text). In other implementations, the resources may not be ranked.
Process 300 generates search results corresponding to the resources, and outputs (314) the search results, e.g., according to the resource ranking, if any. For example, process 300 can output a Web page (e.g., a search results page) listing the search results, which identify the resources.
FIG. 4 depicts an example Web page that presents search options and search results to a user. In this regard, FIG. 4 shows an example Web page 400 for accessing a social networking service. Web page 400 can be displayed on a computing device through a suitable Web browser. Web page 400 may present a number of selectable search options to a user. For example, Web page 400 can include a button 402 that the user can select to initiate a social search of the type described herein. In response to a user selecting Web button 402, a search system provided by the social networking service can retrieve and present a number of search results that are likely to be of interest to the user (for example, by performing process 300). As described above, the search results can be generated based on a predefined type of social engagement signal (or a plurality of predefined signal types).
Web page 400 may present several other search options (which may include a number of user selectable links and/or Web buttons) that can effect retrieval of interesting and/or entertaining search results by the search system. For example, links 404a, 404b, 404c, and 404d can point to respective search results pages listing search results associated with various known or perceived interests of a user. Each of links 404a, 404b, 404c, and 404d may point to a respective search results pages listing social media posts associated with a topic (i.e., “computers”, “basketball”, “Barack Obama”, and “Fantasy Football”) that has been determined to be of interest to the user. In some implementations, links 404a, 404b, 404c, and 404d can be provided by the search system automatically (for example, based on information included in the user's profile). Links may also be provided based on user interaction. For example, a user may specify topics of interest and prompt the search system to provide corresponding topical search links on, for example, the user's profile page. The search system may update the respective search results pages (for example, at predetermined intervals) and provide an indication when new search results have been identified or retrieved. New search results may correspond to search results that have been received since the search results pages were last updated.
As noted above, in some implementations, previous searches can be saved. Accordingly, a search system can present links 404e and 404f to a user for retrieving previously saved searches. In some examples, the search system can update the saved searches (for example, at predetermined intervals) and provide an indication when new search results have been identified or retrieved.
As shown, Web page 400 can also present a number of search results that can be output in response to a search performed by selecting the provided search options, or by entering a search terms into query box 408. In this example, search results 406 are presented in response to a user selecting Web button 402.
Search results 406 may be real-time search results that are both responsive to search criteria and relatively recent. For example, real-time search results can include search results representing resources that were last updated and/or uploaded within a predetermined amount of time (e.g., 60 seconds, 5 minutes, 30 minutes, 60 minutes, etc.). Real-time search results may be updated continuously or at predetermined intervals.
Example resources that may be represented by search results 406 include, but are not limited to, social media Web pages, blogs (e.g., blogs and/or blog posts), microblog Web pages, user profiles, discussion threads, and the like. Such resources can be resources crawled by a search engine (as noted above) or resources received from a provider feed. Example provider feeds include, for example, news feeds, Really Simple Syndication (RSS) feeds, or feeds from content hosting Web sites.
Web page 400 may present one or more social options to users. The social options can allow users to interact with other members of a social networking service. For example, social options 410a, 410b, and 410c can be selected by a user to recommend, comment, and/or share a resource represented by a search result. In this example, a user can recommend the resource represented by a search result by selecting social option 410a. By selecting social option 410a, the user can indicate to other users (through the social networking service) that the represented resource is interesting or entertaining. In some examples, this indication can be used for retrieving future search results for other users, as described below. By selecting social option 410b, the user can add a comment related to the resource. The comment can be incorporated in the content of the resource and/or stored separately by the social networking service. In some implementations, the social networking service can consider the comment as an indication that the resource is entertaining or of interest to the user. By selecting social option 410c, the user can share the resource with other users. Sharing may effect publication of the resource to one or more other associated users (e.g., members of the user's social graph). Sharing the resource can be considered by the social networking service as an indication that the resource is interesting or of interest to the user.
Web page 400 may present several miscellaneous options, in addition to search options 404 and social options 410. For example, the user can select option 412 to save an existing search. Saving a search may allow the user to return to the search results page without resubmitting the query. A search system may save an existing search by saving the list of retrieved search results. The search system can also save the existing search by saving the query associated with the list of search results.
FIG. 5 shows examples of computing devices on which the processes described herein, or portions thereof, may be implemented. In this regard, FIG. 5 shows an example of a generic computing device 500 and a generic mobile computing device 550, one or more of which may be used to implement all or part of the processes described herein. Mobile computing device 550 may be used as a client device of FIG. 1. Other client devices of FIG. 1 may also have the architecture of computing device 500.
Computing device 500 can be any form of digital computers, examples of which include laptops, desktops, workstations, personal digital assistants, servers, blade servers, mainframes, and other appropriate computers. Computing device 550 can be any form of mobile devices, examples of which include personal digital assistants, cellular telephones, smartphones, and other similar computing devices. The components shown here, their connections and relationships, and their functions, are meant to be exemplary only, and are not meant to limit implementations of the technology described and/or claimed in this document.
Computing device 500 includes a processor 502, memory 504, a storage device 506, a high-speed interface 508 connecting to memory 504 and high-speed expansion ports 510, and a low speed interface 512 connecting to low speed bus 514 and storage device 506. Each of the components 502, 504, 506, 508, 510, and 512, are interconnected using various busses, and may be mounted on a common motherboard or in other manners as appropriate. The processor 502 can process instructions for execution within the computing device 500, including instructions stored in the memory 504 or on the storage device 506 to display graphical information for a GUI on an external input/output device, for example, display 516 coupled to high speed interface 508. In other implementations, multiple processors and/or multiple buses may be used, as appropriate, along with multiple memories and types of memory. Also, multiple computing devices 500 may be connected, with each device providing portions of the necessary operations (e.g., as a server bank, a group of blade servers, or a multi-processor system).
The memory 504 stores information within the computing device 500. In one implementation, the memory 504 is a volatile memory unit or units. In another implementation, the memory 504 is a non-volatile memory unit or units. The memory 504 may also be another form of computer-readable medium, examples of which include a magnetic or optical disk.
The storage device 506 is capable of providing mass storage for the computing device 500. In one implementation, the storage device 506 may be or contain a computer-readable medium, examples of which include a floppy disk device, a hard disk device, an optical disk device, or a tape device, a flash memory or other similar solid state memory device, or an array of devices, including devices in a storage area network or other configurations. A computer program product can be tangibly embodied in an information carrier. The computer program product may also contain instructions that, when executed, perform one or more methods, including those described above. The information carrier may be a non-transitory computer- or machine-readable medium, for example, the memory 504, the storage device 506, or memory on processor 502. For example, the information carrier may be a non-transitory, machine-readable storage medium.
The high speed controller 508 manages bandwidth-intensive operations for the computing device 500, while the low speed controller 512 manages lower bandwidth-intensive operations. Such allocation of functions is exemplary only. In one implementation, the high-speed controller 508 is coupled to memory 504, display 516 (e.g., through a graphics processor or accelerator), and to high-speed expansion ports 510, which may accept various expansion cards (not shown). In the implementation, low-speed controller 512 is coupled to storage device 506 and low-speed expansion port 514. The low-speed expansion port, which may include various communication ports (e.g., USB, Bluetooth, Ethernet, wireless Ethernet) may be coupled to one or more input/output devices, e.g., a keyboard, a pointing device, a scanner, or a networking device, e.g., a switch or router, e.g., through a network adapter.
The computing device 500 may be implemented in a number of different forms, as shown in the figure. For example, it may be implemented as a standard server 520, or multiple times in a group of such servers. It may also be implemented as part of a rack server system 524. In addition, it may be implemented in a personal computer, e.g., a laptop computer 522. Alternatively, components from computing device 500 may be combined with other components in a mobile device (not shown), e.g., device 550. Each of such devices may contain one or more of computing device 500, 550, and an entire system may be made up of multiple computing devices 500, 550 communicating with each other.
Computing device 550 includes a processor 552, memory 564, an input/output device, e.g. a display 554, a communication interface 566, and a transceiver 568, among other components. The device 550 may also be provided with a storage device, e.g., a microdrive or other device, to provide additional storage. Each of the components 550, 552, 564, 554, 566, and 568, are interconnected using various buses, and several of the components may be mounted on a common motherboard or in other manners as appropriate.
The processor 552 can execute instructions within the computing device 550, including instructions stored in the memory 564. The processor may be implemented as a chipset of chips that include separate and multiple analog and digital processors. The processor may provide, for example, for coordination of the other components of the device 550, e.g., control of user interfaces, applications run by device 550, and wireless communication by device 550.
