Abstract The method of the present invention combines concept searching, document ranking. high speed and efficiency, browsing capabilities, "intelligent" hypertext, document routing. and summarization (machine abstracting) in an easy-to-use implementation. The method of the present invention also offers Boolean and statistical query options. The method of the present invention is based upon "concept indexing" (an index of "word senses" rather than just words.) It builds its concept index from a "semantic network" of word relationships with word definitions drawn from one or more standard human-language dictionaries. During query, users may select the meaning of a word from the dictionary during query construction, or may allow the method to disambiguate words based on semantic and statistical evidence of meaning. This results in a measurable improvement in precision and recall. Results of searching are retrieved and displayed in ranked order. The ranking process is more sophisticated than prior art systems providing ranking because it takes linguistics and concepts, as well as statistics into account.
