Abstract
A document retrieval system is a quite useful tool in office environments, expecially for professionals who are interested in keeping along with the state of the art of their field by quickly consulting documents. The paper describes the design and the implementation of a document retrieval system based on a concept extraction from documents. Concept extraction is implemented using an internal knowledge representation (semantic network memory) of the subject the documents deal with retrieving concepts from a text is performed by search/inferential algorithms. Advantages of such methods are shown by comparing it to keyword extraction. The prototype system implementation is described. This system is actually in experimental phase. Several test descriptions provide a sketch of the first results.
