## Title
Methods and systems for enforcing parental-control policies on user-generated content

## Abstract

A method for enforcing parental-control policies on user-generated content may include identifying a web document with user-generated content and identifying a set of links in the web document that relate to the user-generated content in the web document. The method may also include identifying a target web document for each link in the set of links and determining a parental-control rating for each link in the set of links based on the target web document. The method may further include generating a composite rating of the web document based on the parental-control rating of each link in the set of links. Various other methods, systems, and computer-readable-storage media are also disclosed.

## Background
BACKGROUND
Children increasingly access the Internet in their everyday activities and may access a variety of content from the Internet. A parent or an organization may deem some content inappropriate for a child and may wish to prevent that child from accessing such content.
If a parent deems Internet content inappropriate, the parent may use parental-control software to block a child from accessing the content. The parent may use the parental-control software to block access to a website with inappropriate content. However, blocking an entire website may be too coarse of a remedy in many cases. For example, an increasing amount of Internet content may be user-generated (e.g., blogs and social networking content). A website that hosts user-generated content may include both appropriate and inappropriate content.
Some parental-control software may help parents automatically block content on a case-by-case basis by scanning for keywords that signal inappropriate content. However, relying on keywords may produce too many false positives and too many false negatives. For example, a keyword that tends to signal inappropriate content may also have benign uses. Further, some inappropriate content may not include keywords that are helpful for identifying the content.
Websites that host user-generated content may pose a further difficulty for parents who wish to prevent their children from submitting inappropriate content. As in the case of blocking user-generated content, blocking the child's creation of content entirely may be too coarse a remedy, while blocking the child's creation of content based on keywords may be too inaccurate.
SUMMARY
As will be described in greater detail below, the instant disclosure generally relates to systems and methods for enforcing parental-control policies on user-generated content by rating web documents linked to the user-generated content and then generating a composite rating for the user-generated content. In some embodiments, a detection module may identify a web document with user-generated content, identify a set of links relating to the user-generated content, and identify a target web document for each link in the set of links. A rating module may then determine a parental-control rating for each link in the set of links, based on the target web document of the link, and generate a composite rating based on the parental-control rating for each link in the set of links.
In some embodiments, the detection module may identify the web document by detecting an attempt to access the web document and determining that the web document includes user-generated content. The detection module may determine that the web document includes user-generated content by determining that the web document is located on a website known for user-generated content (e.g., FACEBOOK.COM or BLOGGER.COM) or by determining that the web document includes a framework for user-generated content (e.g., WORDPRESS or BLOGGER).
The rating module may use a variety of ratings to generate the composite rating of the web document. For example, the rating module may generate the composite rating by determining that a link refers to a content-generating user (e.g., the link points to a user profile) and by determining that the link corresponds to content in the web document (e.g., a comment or a post). The rating module may then determine a reputation rating for the content-generating user and generate the composite rating of the web document with the reputation rating. The rating module may also generate the composite rating of the web document by identifying an incoming link that points to the web document, identifying the source of the incoming link, determining a parental-control rating for the source, and generating the composite rating of the web document with the parental-control rating for the source.
The rating module may also enforce a parental-control policy based on the composite rating. The rating module may enforce the parental-control policy by, for example, blocking access to the web document, blocking access to part of the web document (e.g., a comment, an image, a video, and/or a hyperlink), and/or by blocking an attempt to submit user-generated content to a website.
Features from any of the above-mentioned embodiments may be used in combination with one another in accordance with the general principles described herein. These and other embodiments, features, and advantages will be more fully understood upon reading the following detailed description in conjunction with the accompanying drawings and claims.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Embodiments of the present disclosure provide various methods and systems for enforcing parental-control policies on user-generated content. For example, embodiments of the present disclosure may use one or more modules to identify a web document with user-generated content, identify a set of links relating to the user-generated content, and/or identify a target web document for each link in the set of links. One or more modules may then determine a parental-control rating for each link in the set of links, based on the target web document of the link, and generate a composite rating based on the parental-control rating for each link in the set of links.
Embodiments of the present disclosure may provide various features and advantages not provided by traditional technologies. For example, methods and systems described herein may allow a parent to accurately and selectively block inappropriate user-generated content while allowing a child to access appropriate user-generated content. Additionally, some embodiments described herein may allow a parent to prevent a child from contributing inappropriate content to websites while allowing the child to participate in and contribute appropriately to websites with user-generated content. These and other embodiments, features, and advantages will be more fully understood upon reading the following detailed description in conjunction with the accompanying drawings and claims.
FIG. 1 illustrates an exemplary system 100 for enforcing parental-control policies on user-generated content. System 100 may include modules 110. Modules 110 may include a detection module 112 and a rating module 114. System 110 may also include processor 120. Processor 120 may be configured to execute at least a portion of detection module 112 and/or rating module 114. System 110 may also include a storage device 130. Storage device 130 may include parental-control policies 132. As will be explained in greater detail below, detection module 112 may be programmed to identify a web document with user-generated content, identify a set of links in the web document that relate to the user-generated content, and, for each link in the set of links, identify a target web document. Rating module 114 may be programmed to determine, for each link in the set of links, a parental-control rating for the link based on the target web document and generate a composite rating of the web document based, at least in part, on the parental-control rating of each link in the set of links.
In certain embodiments, one or more of modules 110 in FIG. 1 may represent one or more software applications or programs that, when executed by a computing system, may cause the computing system to perform one or more of the steps disclosed herein. For example, as will be described in greater detail below, one or more of modules 110 may represent software modules configured to run on one or more computing devices, such as computing system 610 in FIG. 6 and/or portions of exemplary network architecture 700 in FIG. 7. One or more of modules 110 in FIG. 1 may also represent all or portions of one or more special-purpose computers configured to perform one or more tasks associated with the steps disclosed herein.
FIG. 2 is a block diagram of an exemplary system 200 having a network 210 and computing subsystems 220, 230, and 240 for enforcing parental-control policies on user-generated content. Computing subsystem 220, 230, and/or 240 generally represent any type or form of computing device capable of reading computer-executable instructions. Examples of computing subsystems 220, 230, and/or 240 may include, without limitation, laptops, desktops, servers, cellular phones, personal digital assistants (PDAs), multimedia players, embedded systems, combinations of one or more of the same, exemplary computing system 610 in FIG. 6, or any other suitable computing device. Computing subsystem 220 may include user-generated content 222, and computing subsystem 230 may include detection module 112 of FIG. 1, rating module 114 of FIG. 1, and storage device 130 of FIG. 1. Storage device 130 may include parental-control-policies 132 of FIG. 1. Computing subsystem 240 may include a graphical interface 242.
Network 210 may include a wide area network (WAN), such as the Internet, or any other network that may provide access to user-generated content. Network 210 may additionally include a local area network (LAN) that connects computing system 230 with computing system 240. Network 210 may additionally or alternatively include any other suitable network technology.
Computing subsystem 220 may include a server that hosts a website. As used herein, a “website” may refer to any collection of cross-referencing or interrelated electronic files available for access across a network. The website may include user-generated content 222. As used herein, “user-generated content” may refer to content in a wider collection of content that cannot be entirely attributed to a single author, content that is not entirely authored by the entity that publishes or hosts it, and/or content that may be evaluated for appropriateness by evaluating content to which it links or refers.
Computing subsystem 230 may include an end-user computing device accessible by a child. As used herein, a “child” may refer to a minor, a dependent, and/or any person subject to content-control policies. Parental-control policies 132 may include content-control policies for enforcement on the child. As used herein, a “parental-control policy” may refer to any content-control policy.
Computing subsystem 240 may include an end-user computing device accessible by a parent. As used herein, a “parent” may refer to any parent, guardian, adult, and/or organization that may apply a parental-control policy to a child. Graphical interface 242 may allow the parent to monitor attempted violations of parent-control policies, view or modify parental-control policies, and/or enforce parental-control policies.
By way of example, a child may operate computing subsystem 230 in an attempt to access user-generated content 222 on computing subsystem 220 through network 210. At least one of modules 110 may access parental-control policies 132 through storage device 130 in order to determine whether to allow the child's access attempt. One or more of modules 110 may perform steps, which are described in greater detail below, to determine how to respond to the child's access attempt. A parent may operate computing system 240 and, through graphical interface 242, observe the access attempt and/or modify a parental-control policy. In other embodiments, graphical interface 242 may be located on computing subsystem 230 (i.e., the same computing system that a child may use). In such embodiments, the parent may administer parental-control policies from the same computing device the child may use to access user-generated content.
FIG. 3 illustrates an exemplary method 300 for enforcing parental-control policies on user-generated content. In some embodiments, the steps in FIG. 3 may be performed by one or more of modules 110. For example, at step 310 detection module 112 in FIG. 1 may identify a web document that includes user-generated content. A web document may include a web page (i.e., an HTML document) and/or any other electronic document or file that a user may access across a network. Detection module 112 may identify the web document in any suitable manner, such as by detecting an attempt to access the web document and determining that the web document includes user-generated content.
Detection module 112 may determine that the web document includes user-generated content in any suitable manner. For example, detection module 112 may determine that the web document includes user-generated content by determining that the web document is located on a website known for user-generated content (e.g., FACEBOOK.COM or BLOGGER.COM). Detection module 112 may determine that the web document is located on a website known for user-generated content by, for instance, parsing the uniform resource locator (URL) of the web document. For example, if the URL of the web document is http://www.facebook.com/profile.php?id=1234567890, detection module 112 may parse the domain facebook.com from the URL and determine that the web document is located on FACEBOOK.COM, a website known for user-generated content.
Detection module 112 may also determine that the web document includes user-generated content by determining that the web document includes a framework for user-generated content (e.g., WORDPRESS or BLOGGER). For example, detection module 112 may parse the web document and determine that the arrangement of the page elements matches a known publishing framework. Additionally or alternatively, detection module 112 may parse the web document and determine that that one or more of the page elements matches an element known to typically include user-generated content.
Returning to FIG. 3, at step 320 detection module 112 may identify a set of links in the web document, where each link in the set of links relates to the user-generated content in the web document. For example, detection module 112 may parse the web document for links. Detection module 112 may exclude from the set of links those links that do not relate to the user-generated content. For instance, detection module 112 may exclude links that pertain to the web site of the web document in general rather than the web document in particular, generic advertisement links, and/or any other links that do not relate to the user-generated content in the web document.
In order to identify only those links which relate to the user-generated content in the web document, detection module 112 may determine a relationship between the link and the user-generated content. The relationship between the link and the user-generated content may exist in a variety of contexts. For example, the relationship between the link and the user-generated content may exist where the user-generated content includes the link, such as a link in a blog post. The relationship between the link and the user-generated content may also exist where link was generated in reference to the user-generated content, such as a related-video link on YOUTUBE.COM may be generated in reference to the original video.
Detection module 112 may also determine a relationship between the link and the user-generated content by determining that the link refers to a content-generating user. For example, the link may point to a profile page of a user on a blogging website, a social network, and/or any other user-generated content platform. After detection module 112 determines that the link refers to a content-generating user, detection module 112 may determine that content in the web document corresponds to the content-generating user. For example, a comment on a blog post may include a link to the author of the comment. Detection module 112 may determine that the comment corresponds to the author.
As will be described in further detail below, rating module 114 may enforce a parental-control policy by blocking a part of the web document if the part of the web document is related to a link which is rated as inappropriate.
A link may include any element of the web document that connects the web document to content outside the web document. For example, the link may include a hyperlink. The link may connect the web document to a static web document or to a dynamically-created web document. A set of links may include one or more links.
Returning to FIG. 3, at step 330 the detection module may identify a target web document of each link in the set of links. For example, the detection module may identify the target web document of a link by retrieving the target web document from a URL provided in the link. The detection module may also identify the target web document by any other suitable method.
At step 340, the rating module may determine a parental-control rating for each link in the set of links. The rating module may base the parental-control rating on the target web document of a link. The rating module may determine the parental-control rating of the link in a variety of ways. For example, the rating module may determine the parental-control rating of the link by determining a URL or site-based category rating of the target web document. For instance, if the target web document is located on a website known for violence, the rating module may rate the link to the target web document accordingly.
The rating module may also determine the parental-control rating of the link recursively. For example, if the target web document contains user-generated content, the rating module may rate the links in the target web document to determine a rating for the link to the target web document. The rating module may also keep track of its recursion in order to avoid infinite recursion due to cross-linked content. For example, the rating module may identify a fixed number of recursion levels. Once the rating module reaches the fixed number of recursion levels, the rating module may go no deeper. Additionally or alternatively, the rating module may keep track of web documents and/or links that it has examined in order to avoid cross-linked recursion. For example, the rating module may record the URL of each link it examines and/or a hash or other identifying feature of each target web document to which the link points. If the rating module encounters the link or target web document again in its recursive rating, the rating module may not descend further into examination of the link or target web document.
Returning to FIG. 3, after determining a parental-control rating for each link in the set of links, at step 350 rating module 114 may generate a composite rating of the web document based, at least in part, on the parental-control rating of each link in the set of links. Rating module 114 may generate the composite rating of the web document by any suitable method. For example, rating module 114 may average the ratings of the links in the set of links or use the rating of the most inappropriate link in the set of links as the composite rating.
Rating module 114 may additionally or alternatively use other information to determine the composite rating. For example, as described above for step 320, detection module 112 may determine the relationship between the link and the user-generated content. Once detection module 112 has determined the relationship between the link and the user-generated content, rating module 114 may determine a reputation rating for the content-generating user. The reputation rating may include any rating that may help to determine the appropriateness of content produced by or connected with the content-generating user. Rating module 114 may determine the reputation rating for the content-generating user in any suitable manner. For example, rating module 114 may examine the content that the content-generating user has created. After rating module 114 has determined the reputation rating for the content-generating user, rating module 114 may generate the composite rating for the web document based on the reputation rating for the content-generating user.
Rating module 114 may also generate the composite rating based on incoming links. For example, rating module 114 may identify an incoming link that points to the web document, identify a source of the incoming link, and determine a parental-control rating for the source of the incoming link. Rating module 114 may determine a parental-control rating for the source of the incoming link by a variety of means, such as a URL or site-based category rating as described earlier, or, if the source of the incoming link includes user-generated content, the recursive method of rating user-generated content as described earlier. In some embodiments, the composite rating may be based on one or more incoming link ratings, one or more outgoing link ratings, one or more reputation ratings, and/or any combination of these ratings and/or other information.
Rating module 114 may further include any other suitable criteria to generate the composite rating. For example, rating module 114 may consider keywords in the web document, community ratings of the web document, and/or analysis of images, videos, or other content embedded in the web document.
After generating the composite rating of the web document, rating module 114 may enforce a parental-control policy based on the composite rating. Rating module 114 may enforce the parental-control policy in any suitable manner. For example, rating module 114 may block access to the web document. Alternatively, as mentioned earlier, rating module 114 may also enforce the parental-control policy by identifying a suspect part of the web document related to a link in the set of links and blocking access to that suspect part. The suspect part of the web document may include a comment, an image, a video, and/or a hyperlink.
Rating module 114 may also enforce the parental-control policy by identifying an attempt to submit user-generated content and blocking the attempt. For example, a child may create user-generated content, such as a blog post, with links to inappropriate content. The child may use a web form to draft and submit the blog post. Detection module 112 and rating module 114 may treat the web document with the web form as a web document with user-generated content, determine that the web document violates a parental-control policy, and block the child from submitting the blog post.
One or more of the steps of the method for enforcing parental-control policies on user-generated content described above may transform a visual display device into a different state. For example, with the transformation, the visual display device may allow a parent to view, manipulate, and enforce parental-control policies on user-generated content.
For the sake of clarity, and by way of example only, FIG. 4 illustrates an exemplary web document 400 to which the embodiments described and/or illustrated herein may be applied. Web document 400 may include template links 410. Template links may include links unrelated to user-generated content, such as template link 412 and template link 414. Web document 400 may also include post 420. Post 420 may include user-generated content. Post 420 may include post links 422, 424, and 426. Post 420 may also include comment 430 with user profile link 432 and comment 440 with user profile link 442.
Detection module 112 may identify web document 400 as a web document with user-generated content. For example, detection module 112 may determine that web document 400 follows the format of a known blog publishing framework. After identifying web document 400, detection module 112 may identify a set of links in web document 400 that relate to the user-generated content in web document 400. For example, detection module 112 may identify post links 422, 424, and 426 as relating to post 420. Detection module 112 may further identify user profile link 432 as relating to comment 430 and user profile link 442 as relating to comment 440. Detection module 112 may exclude template links 410 from the set of links, as template links 410 may not relate to any user-generated content. After identifying the set of links in web document 400, detection module 112 may identify a target web document of each link.
Once detection module 112 identifies a target web document of each link in the set of links, rating module 114 may determine a parental-control rating for each link based on the target web document. For example, rating module 114 may determine that each of post links 422, 424, and 426 are appropriate. Detection module 114 may determine, however, that user profile link 432 and user profile link 442 are inappropriate. In some embodiments, rating module 114 may generate a composite rating based on post links 422, 424, and 426 and user profile links 432 and 442. The composite rating may indicate that web document 400 is inappropriate. Rating module 114 may then enforce a parental-control policy on web document 400 by, for example, blocking access to web document 400.
In other embodiments, rating module 114 may determine that web document 400 would have an appropriate composite rating after the exclusion of user profile links 432 and 442. In such embodiments, rating module 114 may enforce the parental-control policy by blocking a user (e.g., a child) from viewing user profile links 432 and 442 in web document 400. Rating module 114 may further determine that comments 430 and 440 are suspect due to their relationship with user profile links 432 and 442. Rating module 114 may accordingly also exclude comments 430 and 440 from web document 400.
FIG. 5 illustrates an exemplary graphical interface 242 for enforcing parental-control policies on user-generated content. Graphical interface 242 may include violation list 510, details buttons 520, and policy controls 530. Violation list 510 may include attempts to violate a parental-control policy through user-generated content. Violation list 510 may include, for example, the date and/or time of the attempted violation and the URL of the web document. A parent may select one of the attempted policy violations of violation list 510 for further action. Details buttons 520 may allow the parent to inspect the details of the selected violation from violation list 510. For example, the parent may view which parental-control policy triggered the violation and which links in the offending web document were responsible for the violation. The parent may also view details about the website on which the attempted violation occurred. Policy controls 530 may allow the parent to change the access policy for the website of the attempted violation. For example, the parent may determine, after viewing the details of the violation, that access to content from a given website should be allowed, that access to content from the website should always be blocked, or that access to content should depend on analysis of the particular user-generated content.
