Patent Application
20160277485
The present disclosure relates to methods and systems for identifying and aggregating content based on social network data.
Existing content feeds received over the internet are typically preselected according to popularity or predetermined user preferences. With the ever-increasing amount of data available online, these existing content feeds often produce an overwhelming amount of content to the user. The user must then sort through the large amount of content to identify particular items of interest to the user. Many of these content feeds are generated with the assistance (and judgment) of human users, while others are generated using machine learning algorithms. These approaches may not accurately identify content likely to be of interest to a particular user.
Additionally, some content feeds take into account social networking data, where data items that are viewed, selected or opened by a user's social connections are ranked according to relevance to a user reading the content feed. However, these existing systems are typically very slow and need a great deal of time to compile the data. Further, these existing systems often perform batch operations with significant periods of time between the batch operations. Thus, a user cannot receive a content feed that is socially driven in substantially real time. Accordingly, what is needed is a content feed driven by a user's social network data that is capable of compiling content items for a user in substantially real time.
Non-limiting and non-exhaustive embodiments of the present disclosure are described with reference to the following figures, wherein like reference numerals refer to like parts throughout the various figures unless otherwise specified.
In the following description, reference is made to the accompanying drawings that form a part thereof, and in which is shown by way of illustrating specific exemplary embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the concepts disclosed herein, and it is to be understood that modifications to the various disclosed embodiments may be made, and other embodiments may be utilized, without departing from the scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense.
The articles “a” and “an” are used herein to refer to one or to more than one (i.e. to at least one) of the grammatical object of the article. By way of example, “a user” means one user or more than one user. Reference throughout this specification to “one embodiment,” “an embodiment,” “one example,” or “an example” means that a particular feature, structure, or characteristic described in connection with the embodiment or example is included in at least one embodiment of the present disclosure. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” “one example,” or “an example” in various places throughout this specification are not necessarily all referring to the same embodiment or example. Furthermore, the particular features, structures, databases, or characteristics may be combined in any suitable combinations and/or sub-combinations in one or more embodiments or examples. In addition, it should be appreciated that the figures provided herewith are for explanation purposes to persons ordinarily skilled in the art and that the drawings are not necessarily drawn to scale.
Embodiments in accordance with the present disclosure may be embodied as an apparatus, method, or computer program product. Accordingly, the present disclosure may take the form of an entirely hardware-comprised embodiment, an entirely software-comprised embodiment (including firmware, resident software, micro-code, etc.), or an embodiment combining software and hardware examples that may all generally be referred to herein as a “circuit,” “module,” or “system.” Furthermore, embodiments of the present disclosure may take the form of a computer program product embodied in any tangible medium of expression having computer-usable program code embodied in the medium.
Any combination of one or more computer-usable or computer-readable media may be utilized. For example, a computer-readable medium may include one or more of a portable computer diskette, a hard disk, a random access memory (RAM) device, a read-only memory (ROM) device, an erasable programmable read-only memory (EPROM or Flash memory) device, a portable compact disc read-only memory (CDROM), an optical storage device, and a magnetic storage device. Computer program code for carrying out operations of the present disclosure may be written in any combination of one or more programming languages. Such code may be compiled from source code to computer-readable assembly language or machine code suitable for the device or computer on which the code will be executed.
Embodiments may also be implemented in cloud computing environments. In this description and the following claims, “cloud computing” may be defined as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned via virtualization and released with minimal management effort or service provider interaction and then scaled accordingly. A cloud model can be composed of various characteristics (e.g., on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service), service models (e.g., Software as a Service (“SaaS”), Platform as a Service (“PaaS”), and Infrastructure as a Service (“IaaS”)), and deployment models (e.g., private cloud, community cloud, public cloud, and hybrid cloud).
The flow diagrams and block diagrams in the attached figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present disclosure. In this regard, each block in the flow diagrams or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It will also be noted that each block of the block diagrams and/or flow diagrams, and combinations of blocks in the block diagrams and/or flow diagrams, may be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions. These computer program instructions may also be stored in a computer-readable medium that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable medium produce an article of manufacture including instruction means which implement the function/act specified in the flow diagram and/or block diagram block or blocks.
The systems and methods described herein aggregate, filter, and rank content from multiple social network sources. The resulting content feed is presented to a particular user. The ranking of content is at least partially based on interactions with content by other users who have social relationships with the particular user for which the content feed is created. The described systems periodically retrieve content that may be of interest to a user. When the user requests a current content feed, the system can provide the relevant content in substantially real time, thereby providing the user with highly relevant content in a short period of time.
As used herein, “content” (or “content item”) refers to any type of data in any format, such as news articles, documents, pictures, video recordings, audio recordings, event information, discount information, coupons, product information, shopping information, and the like. A “content feed” refers to a stream of multiple content items provided to one or more users. A “social relationship” includes any relationship between two or more users, such as friends, followers, fans, connections, circles, group members, and the like. These social relationships may be limited to relationships within one or more social networks. For example, two users may share as social relationship by both being associated with a common social network, but not share an actual “real world” relationship. In some situations, particular users may communicate exclusively through the social network, but not communicate in any other manner outside the social network. A “social update” (or “user update”) refers to user updates to one or more social network accounts, such as posts, tweets, statuses, status updates, and other updates. As used herein, “social activities” include any type of action or activity related to (e.g., responding to) a social update, such as liking a post, liking a status update, sharing a post, sharing a status update, retweeting a tweet, favoriting a tweet, favoriting a status update, and the like.
Content management server 102 communicates with various systems, services, and devices through data communication network 104. Data communication network 104 may utilize any communication protocol and any type of communication medium. In some embodiments, data communication network 104 is a combination of two or more networks coupled to one another. Content management server 102 also communicates with various systems and devices, such as mobile devices, through cellular communication network 106, which may utilize any communication protocol and any type of communication medium. In some embodiments, cellular communication network 106 is a combination of two or more networks coupled to one another.
As shown in environment 100, a mobile device 110 communicates with content management server 102 through cellular communication network 106. Although a single mobile device 110 is shown in
Additionally, a user device 114 communicates with content management server 102 through data communication network 104. User device 114 includes any type of device capable of communicating with content management server 102 through data communication network 104, such as a tablet computer, a laptop computer, a desktop computer, a portable entertainment device, a portable gaming device, a game console, a set top box, and the like.
Multiple social networks 116, 118, and 120 are also coupled to data communication network 104. Social networks 116, 118, and 120 include any type of social network, such as Facebook, Twitter, LinkedIn, Google+, and the like. As discussed herein, content management server 102 interacts with social networks 116, 118, and 120 to identify, aggregate, and filter content that may be of interest to a particular user. The identified content is displayed to the user in a content feed via mobile device 110, 112 or user device 114. For example, the content feed can be displayed to the user through a web browser application running on mobile device 110, 112 or user device 114. Alternatively, the content feed is displayed to the user through another application running on mobile device 110, 112 or user device 114. In other embodiments, the content feed is provided to the user via an email message (e.g., email digest), text message or other communication system. In some implementations, the systems and methods described herein communicate one or more of the content items contained in the content feed to the user as an alert that is displayed, for example, on mobile device 110, 112 as a text message, application-generated message, alert notification, email alert or similar message.
The described systems and methods can create content feeds, email digests, and other collections of content items at any time based on the user's preferences. Content items are retrieved at periodic intervals so a content feed, email digest or other collection of content can be created at any time of the day with substantially real-time data. As discussed herein, new content items are identified and retrieved at regular intervals, such as every 15 minutes. Thus, when a user requests a content feed or email digest, they are presented with substantially real-time content with minimal delay. In some embodiments, the email digest includes the top five stories from the user's content feed during the preceding 24 hours. The email digest may also include one or more stories from the user's second degree social relationships. As discussed herein, a use may have a separate “second degree content feed” that includes content associated with, for example, “friends of friends.” Further, the email digest may include a top story from a content feed associated with one of the user's top social relationships.
Content management server 102 also includes a social network manager 208, which handles the receiving and processing of data from multiple social networks. In some embodiments, social network manager 208 also manages the storage of social network account information associated with multiple users. A URL (uniform resource locator) processing module 210 performs, for example, various tasks associated with finding the “destination content” associated with a particular URL. Some URLs are redirected to different URLs, which may then be redirected to another URL, and so on. As used herein, “destination content” or a “URL destination” refers to the final content (or URL associated with the final content) that is the “endpoint” of one or more URL redirects.
Content management server 102 also includes a social network relationships manager 212 that maintains information related to various social network relationships between multiple users. A content aggregation module 214 manages the aggregation of content from multiple social networks, as discussed herein. Content management server 102 also includes a content ranking and filtering module 216 that ranks the aggregated content and applies one or more filters to the aggregated content. A cache manager 218 manages cached data used by content management server 102, and a database manager 220 manages the storing and retrieval of data associated with database 108. In some embodiments, environment 100 includes both a cache and a database for storing data. In certain implementations the cache is located within content management server 102. Other embodiments of environment 100 include a database 108, but do not utilize a cache. Thus, cache manager 218 is provided in embodiments that include a cache for storing various information.
Method 300 continues by storing the user's social network account information (e.g., user identifier and authentication token) for future reference at 306. Using the user's social network account information, the method accesses each of the user's social network accounts to retrieve content and other data associated with each social network at 308. In some embodiments, the content and other data is retrieved from multiple social network accounts simultaneously. To access the multiple social network accounts, some implementations use an API (application programming interface) to retrieve data directly from the social networks. Additional details are provided below regarding the process for retrieving content from the user's social network accounts. The retrieved content and other data associated with each social network is stored at 310 to provide fast access to the content in response to future requests from the user. After the new user has been initialized using method 300, the described systems and methods periodically update the content from the user's social network accounts. In some embodiments, the systems and methods update the content from the user's social network accounts every 15 minutes. These embodiments ensure that the system always has the latest content available to present to the user upon request in substantially real time.
After identifying the multiple content items, method 400 analyzes URLs to follow one or more redirects to other URLs and, eventually, identify a URL destination at 406. This URL destination identifies a specific content item. Next, the method filters (or organizes) the URLs by content type at 408. Example content types include news stories, photos, videos, and the like. Method 400 continues by removing duplicate content items at 410. For example, multiple content items may include URLs that identify the same photo or the same news story. In this situation, the duplicate content items are removed such that each content item identifies unique content (as compared to the other content items). In other embodiments, duplicate content items are removed by examining URL patterns and HTML meta tags. Examples include using known patterns to convert mobile pages and print pages to the regular version of a news story URL, or using the Canonical Meta Tag inside a HTML document.
The multiple content items are ranked at 412 based on any number of factors, such as a frequency of social activities by the user's social relationships in the social network accounts, a quantity of social activities by the user's social relationships in the social network accounts, and a recency of the social activities (i.e., how recently the social activities have occurred). For example, if a first content item has been shared by five social relationships and a second content item has been shared by eight social relationships, the second content item is ranked above the first content item. The method may also filter the multiple ranked content items at 414 based on various filtering criteria. Additional details regarding the ranking and filtering of content items are discussed herein with respect to
Method 400 continues by generating, at 416, a customized content feed for the user based on the ranking of the multiple content items. At least a portion of the customized content feed is then displayed to (or communicated to) the user. The customized content feed may include any number of content items. In some embodiments, the number of content items included in the content feed are limited to a top number of content items, such as the top 10 content items or the top 25 content items. In other embodiments, the number of top content items displayed varies depending on the size of the display screen. For example, a smaller screen may have space to display the top five content items, while a larger screen can display the top eight content items from the same content feed or email digest.
Initially, method 500 accesses the latest data retrieved from each of the user's social network accounts at 502. The method analyzes all new URLs identified in the latest data to identify a URL destination 504. As discussed above, the URL destination refers to the final content (or URL associated with the final content) that is the “endpoint” of one or more URL redirects. All blacklisted URLs and all non-content URLs are excluded at 506. When focusing on news stories, examples of non-content URLs include surveys, Foursquare checkins, Yelp reviews, Wikipedia pages, Flickr photos, Youtube videos, and the like. Blacklisted URLs include, for example, inappropriate content and spam content, such as fake news sites. Various entities or individuals can maintain lists of blacklisted content. In some embodiments, software algorithms may identify inappropriate content by analyzing the content to determine the number of words and paragraphs on a page. These software algorithms may also analyze text and photos/videos on a web site to identify spam, pornography or other inappropriate content.
Method 500 aggregates all URLs associated with the user's multiple content items at 508. The remaining URLs are then ranked, at 510, based on various factors, such as a number of social relationships who shared (or performed other social activities) each content item and/or the recency of those shares. Method 500 may also apply one or more optional filters at 512. Filters include, for example, particular time periods, minimum number of social activities to consider ranking a content item, and the like. In a particular implementation, a filter may require a social activity from at least three friends before the content item is considered for ranking. In another implementation, multiple filters may require a content item to be shared by at least two friends in the last four hours to be considered for ranking Other factors that may be used to rank content include ranking content items based on the number of social activities from second degree relationships (e.g., friends of friends), ranking content items based on social activities from all users in a particular group, and ranking content based on social activities of all users of a particular social network. Additionally, ranking of content items may be further based on the publication (or web site) from which the content originates. Finally, method 500 displays, at 514, a first page of a content feed to the user based on the ranked list of URLs and any applied filters.
Method 600 periodically scans the user's social network accounts to identify new content of interest to the user at 604. If one of the periodic scans identifies new content, the method 600 determines whether the new content satisfies the personal alert threshold associated with the user at 606. Initially, users may be assigned a default alert threshold. In some embodiments, the default alert threshold indicates that no alerts are sent during the first 24 hours after a user starts using the system. This time period is referred to as a “restricted period.” In alternate embodiments, the restricted period may be any duration. After the restriction period, the systems and methods analyze the user's content feed during a previous time period, such as the previous 24 hours. The content feed is sorted by the number of social relationships that share (or perform other social activities related to) each content item. A mathematical calculation is performed based on the number of shares of the top content items. In some embodiments, the default alert threshold is set to the number of shares of the highest (or second highest) content item. Alternate embodiments may apply a ratio, such as 80% of the highest number of shares, average the top few highest number of shares, and the like. In some embodiments, the systems and methods define a lowest allowed default alert threshold. An example of the lowest allowed default alert threshold is three. In this example, default alert thresholds of one or two would not be permitted. This prevents the user from receiving too many alerts.
If the new content does not satisfy the personal alert threshold, the method continues its periodic scans at 604. If the new content satisfies the personal alert threshold, the method next determines, at 608, whether a maximum number of alerts have been exceed within a particular time period. For example, a user or a system may define a maximum number of alerts, such as eight alerts, that can be sent during a 24 hour period. This prevents the user from receiving too many alerts in a short period of time. If the maximum number of alerts has been exceeded at 608, the method continues its periodic scans at 604. If the maximum number of alerts has not been exceeded, method 600 determines whether an alert was already sent for the new content at 610. If an alert was already sent to the user, the method continues its periodic scans at 604.
If an alert was not previously sent to the user, method 600 determines whether the particular user is currently in a restricted period at 612. In some embodiments, alerts are restricted during the first 24 hours after a new user begins using the system. For example, the maximum number of alerts may be set to zero during the first 24 hours. This restriction allows the described systems and methods to wait until sufficient content items have been aggregated from the social networks to accurately calculate a default threshold for the new user. Additionally, this initial delay avoids being a nuisance to the new user by sending too many alerts or notifications shortly after starting to user the service. If the user is currently in a restricted period, the method continues its periodic scans at 604. However, if the user is not in a restricted period, method 600 generates an alert that communicates the new content item to the user at 614. The alert communicated to the user may be an email alert, mobile alert, text message, application-generated message, alert notification or other type of alert message. After communicating the alert to the user, the method continues scanning the user's social network accounts for new content.
In some embodiments, each user's alert threshold is recalculated periodically or after particular events. For example, the alert threshold may be recalculated after a user adds or removes a social network from their accounts. Additionally, the alert threshold may be recalculated if a user significantly increases or decreases the number of people they have social relationships with (e.g., significantly increase or decrease the number of people they are following). If the systems and methods described herein frequently identify more candidate alerts for a particular user than the current maximum number of alerts supported, the system may consider recalculating the user's alert threshold. In situations where the user has specified their own alert threshold, the systems and methods described herein may not change that alert threshold unless instructed by (or approved by) the user.
In some embodiments, when method 600 is determining whether to send an alert to a user, the method may also consider other factors, such as the rate at which a particular content item accumulates social activity from multiple social relationships. For example, if a particular content item reaches the user's alert threshold within 30 minutes, that content item is more likely to be sent to the user as an alert than another content item that takes several hours to reach the user's alert threshold.
Initially, method 700 identifies a list of multiple social network users at 702. As mentioned above, this list of social network users may be associated with a particular topic or area of interest. In a particular embodiment, the list of social network users is a Twitter list. In other embodiments, the list of social network users can be a list of users from any social network, a group of users associated with one or more social networks, a list of other users created by the user who will receive the customized content feed, and the like. The method continues by identifying content items related to social updates of the multiple social network users at 704. For example, the identified content items are items that have been posted, tweeted, and included in status updates of the multiple social network users. In a particular embodiment that uses a Twitter list, the described systems and methods periodically request all new statuses tweeted by people on the Twitter list (e.g., using an API for the Twitter social network). Those new statuses are the content items that are filtered and ranked (as discussed below) to generate a customized content feed.
After identifying the content items at 704, the method analyzes URLs to follow redirects and identify a URL destination for content items at 706. As mentioned above, the URL destination identifies a specific content item. Next, method 700 filters (or organizes) the URLs by content type at 708. Example content types include news stories, photos, videos, and the like. The method continues by removing duplicate content items at 710. For example, multiple content items may include URLs that identify the same photo or the same news story. In this situation, the duplicate content items are removed such that each content item identifies unique content (as compared to the other content items).
The multiple content items are ranked at 712. Method 700 may also filter the multiple ranked content items at 714 based on various filtering criteria. Additional details regarding the ranking and filtering of content items are discussed herein with respect to
In some embodiments, the described systems and methods also generate a “second degree content feed,” which is also referred to as a “friends of friends feed.” This second degree content feed is created in a manner similar to the main content feed discussed herein, but instead looks at who user's social relationships follow. For example, the friends of the user's friends, people followed by the user's social relationships, fans of the user's social relationships, connections with the user's social relationships, and the like. So, instead of looking at social relationships of the particular user (i.e., first degree social relationships), the systems and methods identify who those social relationships follow (or have other social relationships with). The second degree content feed excludes people with which the particular user already has a social relationship. This second degree content feed creates an aggregated feed of content items that does not include content items included in the main content feed (i.e., the first degree content feed), to avoid being redundant with the main content feed.
As discussed herein, a “digest email” is sent to a user each day and identifies top content items from the user's main content feed (or second degree content feed). In some embodiments, a user can subscribe (via email) to any content feed created by the described systems and methods. A user does not need to be a “registered user” of the system and does not need to have created their own customized content feed to subscribe to another content feed created by another user or created by an entity providing the systems and methods described herein. After a user subscribes by email to a content feed, that user will receive the top content items from that content feed by email once a day. In other embodiments, the user (or the system) may define email delivery at different intervals, such as twice per day or once every 48 hours. In a particular implementation, the systems and methods attempt to determine the user's geographic location so that an email with the top content items can be sent to the user each morning (based on their local time zone). Alternatively, the user can define a particular time they want to receive the email messages. An “unsubscribe link” is provided in each email message that allows the user to unsubscribe from future emails. In some embodiments, an “edit delivery options” link may be provided in each email message that allows the user to change email delivery frequency and delivery time(s).
In particular embodiments, content management server 102 performs multiple tasks in parallel to support the substantially real-time operation of the described systems and methods. For example, content management server 102 may utilize multiple processors, servers, or virtual machines to analyze multiple URLs and follow their HTTP redirects simultaneously. This processing may be performed in parallel across multiple social networks for multiple different users. Additionally, the content management server 102 can perform various tasks asynchronously to ensure that substantially real-time content items are available to a user upon request. Thus, instead of waiting for a user request for content, the systems and methods described herein proactively retrieve and process relevant content from multiple sources, then store the content items for immediate access upon receipt of the user request.
In some embodiments, users who may not have their own content feed can look at the content feeds of other users. For example, a user may look at the content feed of a friend, a celebrity, or other user to see what content is contained in the other person's content feed. A particular user may be interested in the content items that are identified and ranked (as discussed herein) for one of their favorite celebrities or best friend. In some implementations, private content from the other user's social networks is filtered out of their publicly available content feed. In some embodiments, the described systems and methods these user content feeds are limited to public social networks to avoid disclosure of private content in the content feed. In alternate embodiments, private social networks may be supported, but only the public information from those social networks (or other social networks) are provided in the content feed.
