  • Patent number: 6434550
    Abstract: An information retrieval system allows a user to search a database of informational items for a desired informational item, and presents the search result in the form of matching index entries in the order of relevance. The information retrieval system in accordance with the principles of the present invention assigns a relevance rating to each of the index entries without requiring an explicit input from the user with respect to the usefulness or the relevance of the retrieved information corresponding to the respective index entries. When the user selects and retrieves an informational item through a list of index entries presented by the retrieval system, as a result of a search, the relevance rating of the selected informational item is increased by a predetermined amount.
