Abstract:
1. A method for ranking web documents including user generated content (UGC) with respect to search results generated by a search engine, the method comprising: recognizing a UGC data field from a web document located at a web location; calculating, with a processor, a document goodness factor for the web document, the document goodness factor measuring overall quality of the web document; calculating, with a processor, an author rank for an author of the UGC data field; calculating a web location rank for the web location; generating a rating factor for the UGC data field based on the document goodness factor, the author rank and the web location rank; boosting the web document in a search result set of web documents to a higher ranking above a second web document by applying a damping factor that boosts the web document in the search result set based on a difference between a number of web documents that have been assigned to root categories associated with the web document and the second web document, divided by a total number of the web documents assigned to the root categories associated with the web document and the second web document; and outputting a search result including the UGC data field positioned in the search results based on the rating factor and the damping factor.
