Abstract

An enhancement and retrieval method for natural language data using a computer is disclosed. The method includes executing linguistic analysis upon a text corpus file to derive morphological, part-of-speech information as well as lexical variants corresponding to respective corpus words. The derived linguistic information is then used to construct an enhanced text corpus file. A query text file is linguistically analyzed to construct a plurality of trigger token morphemes which are then used to construct a search mask stream which is correlated with the enhanced text corpus file. A match between the search mask stream and the enhanced corpus file allows a user to retrieve selected portions of the enhanced text corpus.
