AKSHR: A novel framework for a Domain-specific Hidden Web Crawler
Komal Kumar Bhatia, Anukrati Sharma, Rosy Madaan · 2010
Existing search engines crawl and index surface web, ignoring hidden web which otherwise contains more than 500 times of information than PIW. In this paper, a Domain-specific Hidden Web Crawler (AKSHR) is being proposed. The framework extracts hidden web pages by accruing benefits of its three unique features: 1) automatic downloading of search interfaces to crawl hidden web databases, 2) identification of semantic mappings between search interface elements by using a novel approach called DSIM (Domain-specific Interface Mapper), and 3) the capability to automatic filling of search interfaces. The effectiveness of proposed framework has been evaluated through experiments using real web sites and encouraging preliminary results were obtained.
