Research on Middleware of Automatic Finding and Integration of Deep Web Query Interface

In this paper, the Deep Web technologies are analyzed and discussed, and a middleware of finding and integrating Deep Web query interface automatically is proposed. This middleware extracts the attributes of query interfaces and judges them whether interfaces of Web databases by computing the similarity between them; it can also cluster query interfaces and construct an integrated query interface. This middleware provides a practical tool for finding query interface automatically and constructing integrated query interfaces.
