Abstract:

The Deep Web is considered as a vital gap in search engine coverage. Large portion of the web is made up of deep web contents. Many systems and techniques have been proposed to surface the deep web content. Current techniques do not support crawl based web contents behind AJAX or JavaScript forms. The AJAX based forms are loaded dynamically at client side script due to which pre-cashing is not possible. Traditional crawlers are unable to crawl and index dynamic contents. A solution is presented in this paper to solve this problem. AJAX based forms have been analyzed to extract the relevant information from database. The information extracted is indexed for retrieval from database. Further work can be done to accommodate HTML or AJAX based information.
