PURPOSE: To lighten the load of retrieval and decision processing by making it easy to select a necessary document out of retrieval results and eliminating the need to classify terms. CONSTITUTION: An input document α as a routine document is decomposed into plural constituent terms, which are set as reference terms γ. Words similar to standard words matching the reference terms γ are stored in a similar word storage area βtogether with similarities by referring to a term dictionary (f). The similar words in this area are rearranged to obtain words similar to the reference terms γ, and those similar words are set as document retrieval reference terms. As for a document data base (g) where similar documents are stored and a retrieval area is set, a document having terms similar to the terms for document retrieval is stored as a similar document in a similar document storage area ε. The similar documents in this area are rearranged to find the similarities between the input document and similar documents and store them in the similar document storage area ε, and a similar document corresponding to the input document α is outputted. |
