碩士 === 東吳大學 === 資訊管理學系 === 102 === In recent years, in practice, the use of XML technology for heterogeneous data integration is a very important issue. Most of the current framework integrating mechanism, focusing on the use of XML schema information to identify nodes that can be integrated. However, this is not an effective way to solve the heterogeneous problems arose from integration and the influence of the lack of reference information. The other integration mechanisms, is focused on the XML document instance information. Although it is possible to obtain high precision through great data matching method, in case of the high duplication, we can not get a higher level of recall. Therefore, this research is focused on XML schema and XML instance for schema integration. In order to enhance the integration of the recall and precision, the research utilizing the characteristics of XML schema and XML instance to merge similarity of each individual nodes. Through this merger mechanisms to increase the recall and precision. This research using the mechanism in practice to prove the feasibility and the practicability.
