This paper reports on some revent developments in our natural language text retrieval system. The system uses advanced natural language processing techniques to enhance the effectiveness of term-based document retrieval. Th backbone of our system is a traditional statistical engine which builds inverted index files from pre-processed documents and then searches and ranks the documents in response to user queries. Natural language processing is used to (1) preprocess the document in order to extract content-carrying term, (2) discover inter-term dependencies and build a conceptual hierarchy specific to the database domain, and (3) process user's natural language requests into effective search queries. While the general desigh of the system has not changed since TREC-2 conference, we nonetheless replaced several components and added a number of new features which are describes in the present paper. While the general design of the system has not changed since TREC-1 conference, we nonetheless replaced several components and added a number of new features which are described in the present paper.
