摘要：

The Web is based on a browsing paradigm that makes it difficult to retrieve compositive information from multiple sites. Web information integration systems,as a sophisticated solution to this problem,enable easy retrieval for comprehensive information from the Web. Based on a prototype we have implemented a Web information integration system,which is called Aoede.
