摘要: Many databases have become Web-accessible through form-based search interfaces (i.e., forms) that allow users to specify complex and precise queries access the underlying databases. In general, such a Web interface can be considered as containing an schema with multiple attributes rich semantic/meta information; however, is not formally defined on interface. applications, database integration deep crawling, require construction of schemas. this paper, we introduce model for interfaces, present tool (WISE-iExtractor) automatically extracting deriving all needed information construct Our experimental results real indicate highly effective.
