Abstract: A system may receive a request for comments associated with a particular document, identify a comment associated with the particular document, generate an objective score for the comment that is independent of a user associated with the request, identify the user associated with the request, generate a subjective score for the comment based on parameters associated with the identified user, generate a combined score for the comment by combining the objective score and the subjective score, and provide the comment, ranked based on the combined score, to the user for presentation with the particular document.

Abstract: A system may aggregate highlighting information associated with a document that includes a number of elements. The highlighting information may identify one or more of the elements that have been highlighted by a group of users. The system may determine weight values for the one or more elements, generate information associated with the document based on the weight values, and provide the information.

Abstract: Systems and techniques for displaying information associated with multiple accounts of multiple social media websites owned by an owner. In one implementation, a webpage accessed by a user can be determined to be a webpage of a social media website; data can be obtained from the webpage identifiable with an owner of an account of the social media website in which the owner of the account is not the user; based on the data from the accessed webpage identifiable with the owner, another social media webpage associated with another account of the owner for another social media website can be identified; data associated with the other social media webpage can be obtained; and the data associated with the other account can be provided for display with the accessed webpage.

Abstract: A system may receive a request for comments associated with a particular document, identify a comment associated with the particular document, generate an objective score for the comment that is independent of a user associated with the request, identify the user associated with the request, generate a subjective score for the comment based on parameters associated with the identified user, generate a combined score for the comment by combining the objective score and the subjective score, and provide the comment, ranked based on the combined score, to the user for presentation with the particular document.

Abstract: System, methods, and apparatus for attribute-based rating of authors and content. In some methods, first content authored by a first author having an attribute that is common to other authors is received. A second author having the attribute is identified as well as content authored by the second author. A user feedback base rating that is assigned to the second author is identified. An initial rating for the first content is generated based on the user feedback based rating that is assigned to the second author, and the initial rating is assigned to the first content.

Abstract: One or more server devices may receive an indication that a particular user has accessed a particular document. The one or more server devices may determine whether the particular document has been flagged as needing comments, and retrieve an author likelihood score for the particular user when the particular document has been flagged as needing comment. The one or more server devices may determine whether the retrieved author likelihood score is greater than a particular threshold, and provide a suggestion to the user to write a comment about the particular document when the author likelihood score is greater than the particular threshold.

Abstract: A system and method for determining whether a user interface is properly injected on an electronic device are provided. Web site data for a web site is accessed, additional code are injected into the accessed web site data and the web site based on the injected additional code is provided for display. An actual image of a user interface corresponding to the displayed web site is obtained. An expected image of the user interface in which the additional code is properly injected into the web site is received. The expected image of the user interface with the actual image of the user interface are compared. In a case where the expected image of the user interface and the actual image of the user interface do not match, an error message is generated and notification of the error message is provided to the electronic device.

Abstract: A method, performed by one or more server devices, includes receiving an abuse report from a user, where the abuse report indicates that a comment associated with a document violates a policy associated with providing comments to users; retrieving a trust score of the user, where the trust score is based on a difference between a quantity of valid abuse reports previously generated by the user and a quantity of invalid abuse reports previously generated by the user; generating or adjusting a removal score of the comment based on the retrieved trust score of the user; comparing the removal score to a removal threshold; and removing the comment from further presentation to users if the removal score of the comment is greater than the removal threshold.
