| Abstract: | The main retrieval method in NSTL was based on keyword matching, which affected precision and recall. In order to improve services quality of the retrieval, the authors use the semantic resource contained in documents to construct a semantic resource database. The principle and methods of extracting the semantic resource, and the structure and construction of the semantic resource database are elaborated. This database is also applied into NSTL system to cluster the results and show the relevant results, which will help the users to understand the retrieval results. |
