A large amount of information on the Web, stored behind search interfaces cannot be indexed by general-purpose search engines as it is dynamically generated through querying databases. Such databases called Hidden Web or Deep Web contains high quality information. Deep web contents are generated only when queries are asked via a search interface, rendering interface integration a critical problem in many application domains, such as: semantic web, data warehouses and e-commerce, etc. Many different integration solutions have been proposed so far.
