Full-text searching techniques have been extensively used in the area of information retrieval. However, the full-text searching techniques are often insufficient to retrieve meaningful or valuable documents since the basic idea of these techniques is word or phrase matching, not concept matching. A Chinese document retrieval method enhanced by concept base is proposed in this paper. The main idea of this method is to build a common Chinese concept base to provide a shared understanding of concepts. This enhanced method can take advantage of the concept base when analyzing and indexing documents, and when searching documents. The document management system can use this method to improve the retrieval performance.
