## Background
BACKGROUND OF THE INVENTION
Field of the Invention
The disclosed embodiments relate in general to the field of social networking technology and in particular to computer-implemented systems and methods for detecting objectionable content, such as pornographic videos in a social networking context.
Description of the Related Art
Various methods exist in the art for detecting pornographic videos and images. The most obvious method is to have human moderators manually review, classify and, if appropriate, block all content uploaded by the users. However, for large social networks, where users upload thousands or even millions of content files daily, this method is highly impractical.
On the other hand, most of automated methods for content classification rely on image or video frame analysis and have varying reliability. For example, one such method is based on detecting skin color tones within the center region of the images, as pornographic images and videos tend to have a lot of skin in the picture, see Jiann-Shu Lee et al., Naked image detection based on adaptive and extensible skin color model, Pattern Recognition 40 (2007) 2261-2270. However, while this algorithm achieves 80% effectiveness of port detection, it is also prone to generating a very high false alarm rates.
Another algorithm relies on human users to flag pornographic content, which is subsequently manually reviewed by moderators, who make the final content classification decisions. However, this method also performs relatively poorly as flagging the inappropriate content requires an extra effort from the user, which negatively impacts user participation.
Yet another method relies on content file metadata analysis, which looks for pornography-related key phrases in the file names and other available textual components associated with the content. Needless to say that this method is also error-prone as the content metadata is not always indicative of the type of content itself. In addition, widely available metadata scrubbers make pornography detection using this method an even more challenging task.
Therefore, new and improved systems and methods for detecting pornographic materials in social networks are needed that are not subject to above and other deficiencies of the conventional technology.

DETAILED DESCRIPTION
In the following detailed description, reference will be made to the accompanying drawing(s), in which identical functional elements are designated with like numerals. The aforementioned accompanying drawings show by way of illustration, and not by way of limitation, specific embodiments and implementations consistent with principles of the present invention. These implementations are described in sufficient detail to enable those skilled in the art to practice the invention and it is to be understood that other implementations may be utilized and that structural changes and/or substitutions of various elements may be made without departing from the scope and spirit of present invention. The following detailed description is, therefore, not to be construed in a limited sense. Additionally, the various embodiments of the invention as described may be implemented in the form of a software running on a general purpose computer, in the form of a specialized hardware, or combination of software and hardware.
In accordance with one or more embodiments described herein, there is provided a system and method for detecting pornographic or other objectionable content, such as pornographic videos in a social network without requiring any extra actions on the part of the user. Most social networks offer their users “liking” or “reposting” functionality, wherein specific content identified by the user appears in user's activity (news) feed. In most social networks, user's “liking” or “reposting” of the content is visible to all user's friends. At the same time, vast majority of social network users do not wish others to know that they have watched pornographic or other objectionable content. Therefore, while social network users may privately watch pornographic content, users are very unlikely to “like” or “repost” such content for the fear of other users seeing it in their activity log.
Based on this observation, there is provided an embodiment of a system and method for detecting pornographic or other objectionable content, such as videos in a social network. In one or more embodiments, the system is configured to select content with relatively high number of views by the users. For example, media files may be selected that have number of user views exceeding a predetermine threshold. In one or more embodiments, the selected content is then sorted or filtered based on a ratio of number of views to the number of likes and/or reposts. As would be appreciated by persons of ordinary skill in the art, as most users do not wish others to know that they have watched pornographic or other objectionable content, for most pornographic or other objectionable videos and images the aforesaid ratio will be high. In one or more embodiments, for content selection purposes, a second threshold may be applied to the aforesaid ratio.
In one or more embodiments, the selected content with high ratio of number of views to the number of likes and/or reposts is then selected and provided to human moderatos for manual review and classification. As would be appreciated by persons of ordinary skill in the art, the number of such content files would be manageable for human moderators to review.
Specific embodiments of the systems and methods for detecting pornographic or other objectionable content, such as videos or photographic content, in a social networking context, will now be described in detail. FIG. 1 illustrates an exemplary architecture of a system 100 for detecting pornographic or other objectionable content in a social network. In the shown embodiment, users access the video content available on a social network using user's computers 101 and mobile devices 102. The aforesaid user's computers 101 and mobile devices 102 are configured to issue video content play requests via the Internet 103 to multiple web servers 104 of the social network infrastructure. The video play functionality in response to the user's content play requests is provided by the video servers 105 communicatively coupled with the web servers 104.
Each user video play request is monitored and recorded in one or more tables of the database 107 by a video statistic collector 106, which is communicatively coupled, via a data interconnect, with each of the video servers 105 as well as the database 107. In addition to video play request statistics, the video statistic collector 106 may also record in the database 107 various statistics related to social network user's liking and reposting of the videos and other content. The database 107 may be implemented based on any now known or later developed type of database management system, such as a relational database management system, including, without limitation, MySQL, Oracle, SQL Server, DB2, SQL Anywhere, PostgreSQL, SQLite, Firebird and/or MaxDB, which are well-known to persons of skill in the art. In an alternative embodiment, a cloud-based distributed database, such as Amazon Relational Database Service (Amazon RDS), well known to persons of ordinary skill in the art, may also be used to implement the database 107. It should be noted that the data stored in the tables of the database 107
The administrator (moderator) of the social network directly accesses the administrator's computer 109, which is also connected to the Internet 103 and is configured to access a video administrator server 108, which is also communicatively coupled with the video statistics database 107. In one or more embodiments, the video administrator server 108 in conjunction with the database 107 runs queries on the video access/like/repost statistics stored in the database tables of the database 107 and identify suspected pornographic content. In one or more embodiments, the suspected pornographic or other objectionable content is displayed to the administrator (moderator) via a user interface, such as web user interface, of the administrator's computer 109. In one embodiment, the content for review by the administrator (moderator) is displayed in a form of a sorted list. Administrator (moderator) is given the ability to view the listed content and to manually flag the pornographic or other objectionable content, which is subsequently blocked from the social network.
FIG. 2 illustrates data flows 200 among various components of a system for detecting pornographic or other objectionable content in a social network. The social network user 201 directly accessing the personal computer, tablet or mobile device 101 views attempts to view a movie on a social network using the personal computer, tablet or mobile device 101. In response to user's instruction, the personal computer, tablet or mobile device 101 sends a network request 203 for the subject video content. In one or more embodiments, the request 203 is an HTTP request. The request 203 is transmitted through the network, such as the Internet 103 to the social networking web server 104. In one or more embodiments, the aforesaid web server 104 may be of any known of later developed type, including, without limitation, Apache, Microsoft IIS, nginx, Google GWS, lighttpd and Sun Microsystems SunOne.
Upon receiving the content request 203 from the personal computer, tablet or mobile device 101, the web server 104 sends a request 204 for the content to the video server 105. The video server 105, in turn, logs the content view attempt 205 in the appropriate table of the content storage database 202, retrieves the requested content from the content storage database 202 and returns the retrieved content via the network to the web server 104. The information 206 on the subject content view attempt by the user is subsequently transmitted by the video server 105 to a video statistics collector 106, which records the information on the content view attempt by the user in the appropriate table of the statistics database 107. In one or more embodiments, the statistics database 107 stores the complete statistics on access as well as user likes and reposts of all the content available on the social network.
The video statistics collector 106 periodically executes a statics analysis software application, which may select the content files with a predetermined minimal number of user views and predetermined minimal ratio of user view to user liker and/or reposts. In the same or different embodiment, the statics analysis software application may order the content files based on the ratio of user view to user liker and/or reposts. The information on the selected sorted content is stored by the video statistics collector 106 in the statistics database 107. The content moderator server 108 requests this information on the selected sorted content 208 and transmits this information 209, for example in the HTML format, via the Internet 103, to the content moderator computer system 109. The sorted content is shown to the moderator in HTML for using a conventional web browser. The human moderator reviews the sorted content and makes appropriate classification (pornography or not, see 211). The moderator's decision 210 is sent via the Internet back to the content moderator server 108, wherein it is analyzed. Based on moderator's classification, the content moderator server 108 either sends a request 212 to block the subject content, if it contains pornography or other objectionable material, or a request 213 to mark the content as moderated and approved to the content storage database 202. Based on either of the requests 212 or 213, the appropriate record is made in the content storage database 202, which determines how the content is handled in the future.
FIG. 3 illustrates an exemplary operating sequence 300 of an embodiment of a system for detecting pornographic or other objectionable content in a social network. First, at step 301 the user takes an action in connection with the content. Exemplary actions may include viewing, liking and/or reposting (sharing) the content. Exemplary types of the content may be video content or pictorial content. At step 302, the system received user's action and updates action statistics associated with the content, which may be stored in the statistics database 107 described above in connection with FIGS. 1 and 2. At step 303, the video statistics collector 106 determines whether the number of views of the content exceeds a predetermined number (N). Of so, the operation proceeds to step 304, whereupon the content suspicion score equal to the ratio of the number of user content views to user content likes and/or reposts is calculated. Subsequently, at step 305, the calculated content suspicion score is stored in the content database 202. The process terminates ate step 306.
FIG. 4 illustrates an exemplary operating sequence 400 of an embodiment of a system for detecting pornographic or other objectionable content in a social network. At step 401, the administrator (moderator) opens a suspected pornography or other objectionable content review web page using a web browser executing on moderator computer system 109. In response, the video moderation server 108 selects content items from the content statistics database 107, which have largest content suspicion scores calculated at step 304 of the process 300. At step 403, the moderation server 108 creates an HTML report with ordered list of selected content items ranked in accordance with the calculated content suspicion scores. It should be noted that the invention is not limited to only HTML reports and reports of any other encoding, format or type may be used. This report is transmitted to the moderator using the network, such as Internet. The moderator reviews the report and manually classifies the content. Moderator's decision is sent back to the moderation server 108 and analyzed at step 404. If the content is determined by the moderator to have the pornographic material, the content is blocked in the content database 202, by means of sending the content block request 212 to the database 202 illustrated in FIG. 2, see step 405. On the other hand, if it is determined that the content has no pornography or other objectionable material, the moderation server 108 issues the request 213 in FIG. 2 and the content is marked as approved in the content database 202, see step 406. The process subsequently terminates at step 407. In one or more embodiments, after the moderator has reviewed the specific video or other content, the content is appropriately flagged (in the database or otherwise) such that it is no longer shown to the moderator (e.g. it is not included in the report with ordered list of selected content items ranked in accordance with the calculated content suspicion scores).
FIG. 5 illustrates an exemplary embodiment of a graphical user interface 500 of an embodiment of a system for detecting pornographic or other objectionable content in a social network context. In one embodiment, the graphical user interface 500 is a web user interface generated using a web browser executing on the administrator (moderator) computer system 109. The graphical user interface 500 incorporates a ranked list of content items 501, which are to be reviewed by the administrator (moderator). To this end, the administrator (moderator) is provided with controls 503 for playing the listed content items. The administrator (moderator) marks the content as approved or not approved (e.g. containing pornography, blocked) using the control elements 505 and 504, respectively, see FIG. 5. To assist the administrator (moderator) in content review, the graphical user interface 500 additionally incorporates the content rankings 506 as well as calculated content suspicion scores 502. It should be noted that the graphical user interface may additionally incorporate other information related to content, such as content identified, content owner, content title, content advertising status and the like. Thus, many variations of the graphical user interface 500 are possible and the shown embodiment should not be construed in a limited sense.
