ABSTRACT:
A document retrieval system is provided with an original sentence processing unit which sets a plurality of sentence types for identifying the contents of sentences, such as "OPINION" and "PROPOSAL," prepares sentence-unit excerpt sentence data classified according to the sentence types from an original sentence database storing original sentence data constituting documents, and stores the excerpt sentence data as excerpt sentence database. The original sentence processing unit comprises a type determination section for extracting excerpt sentence data corresponding to a designated sentence type, and a shaping section for shaping the excerpt sentence data in a predetermined format, e.g., in such a format that a conjunctive is deleted.
