  • Natural language information retrieval system and method
    Patent number: 6081774
    Abstract: An information retrieval system that represents the content of a language-based database being searched as well as the user's natural language query. In accordance with one aspect of the invention, the information retrieval system includes a non-real-time development system for automatically creating a database index having one or more content-based database keywords of the data base; and a real-time retrieval system that, in response to a user's natural language query, searches the keyword index for one or more content-based query keywords derived from the natural language query. The development system and the retrieval system morphologically, syntactically and linguistically analyze the data base and the natural language query, respectively, to generate the one or more database keywords and query keywords representing the content of the database and the natural language query, respectively.
