Web information access today primarily relies on search engines. Current search engines cannot make index to the pages which are generated automatically by the back -- end databases called invisible web or deep web. The information is hidden behind HTML forms and is only available in response to user's request. In this paper a system based on domain and keyword specific information extraction is described.
