Abstract: Personalization of content of a web site for a user based on a web site that a user arrives from is disclosed. For example, the content of the web site from which the user arrives (i.e., the originating page), as well as the content of the web page the user has arrived to (i.e., the target page), may be categorized as pertaining to particular subjects or topics. Any time a user comes from an originating page, the subject categories for the originating page and the target page may be compared to determine if like categories exist between the pages. In the event that like categories are found, the target page may be personalized based on those categories.

Abstract: Systems, methods and articles of manufacture are disclosed for identifying a training document for a content classifier. One or more thresholds may be defined for designating a document as a training document for a content classifier. A plurality of documents may be evaluated to compute a score for each respective document. The score may represent suitability of a document for training the content classifier with respect to a category. The score may be computed based on content of the plurality of documents, metadata of the plurality of documents, link structure of the plurality of documents, user feedback (e.g., user supplied document tags) received for the plurality of documents, and document metrics received for the plurality of documents. Based on the computed scores, a training document may be selected. The content classifier may be trained using the selected training document.

Abstract: Systems, methods and articles of manufacture are disclosed for generating search results based on user feedback. A request may be received to generate search results retrieved using a search string. The request may include user feedback for one or more selected documents of the search results. Improved search results may be generated based on the search results and the feedback for one or more selected documents of the search results. The improved search results may be output to a graphical display device.
