Searching and Integrating Query Interfaces using Domain Ontology

In addition to billions of Web pages indexed by search engines, the Web also contains a large number of databases whose contents is 500 times larger than Surface Web and are only accessible through query interfaces. This type of web is known as Hidden Web. Its content is out of reach of traditional search engines and its growth is increasing at extraordinary rate. To search the hidden web data, one has to fill these HTML forms manually. That's why Search query interfaces are considered as entrance to Hidden web databases. So, to explore the Hidden Web, we must explore its entrance first. Many different integration solutions have been proposed so far. This paper proposes a technique to detect and construct an integrated query interface that integrates a set of web interfaces over a given domain of interest. This interface is used to fire the queries over various search interfaces of hidden web sites. The proposed strategy does that by focusing the crawl on a given topic i.e by wisely looking at domain ontology which leads to pages that contain domain specific search forms.
