DeepWeb data extraction using query string formation

Due to the speedy growth of the WWW, the web hasn't only “broaden” but also “deepened” in its size. But only a portion of the web is included in the indices of current web search engines, a huge portion of the web hidden behind web search form (search interface). This paper proposes a prototype DWCE which interacts with different websites in order to build efficient search query interface which in turn extract deep web pages that would be of great value to human users. In addition to this, a comparative study of DWCE with Google search engine is also discussed.
