| Abstract: | According to the E-Government documents characters, the weight of the terms in documents and queries were calculated based on E-Government thesaurus. Similarity between query and documents was obtained through computing the similarity between weigh terms of documents and query, and most matching documents were provided. At the same time E- Government document metadata is organized in semantic web. E-Government document can also be retrieved as searching for metadata in semantic web, The documents retrieved is approached in semantic web with metadata to benefit logic reasoning. |
