Abstract: Systems and methods for evaluating members' comments in a social networking based system are disclosed. A social networking system receives a content item, from a first client system, for inclusion in a first database associated with a social networking system. The system receives a request from a second client system, wherein the request specifies a specific content item and one or more related comments. The system accesses comments associated with the content item, wherein the one or more comments are stored in a second database associated with the social networking system. The system analyzes each comment to generate a comment relevance score. The system selects a predetermined number of comments based on the comment relevance score for each comment in the one or more comments. The system transmits the requested content item and the predetermined number of selected comments to the second client system.
