    Implementation of a Hidden Web crawler
    (University of M'sila, 2015-06-10) MAHAMEDI, Soundous; Supervisor: SAOUDI, Lalia
    Current-day crawlers retrieve content only from the publicly indexable Web, i.e., the set of web pages reachable purely by following hypertext links, ignoring search forms and pages that require authorization or prior registration. In particular, they ignore the tremendous amount of high quality content "hidden" behind search forms, in large searchable electronic databases. In this work, we provide a framework for addressing the problem of extracting content from this hidden Web, that is why we have built a task-specific hidden Web crawler called the Intelligent Hidden Web Crawler (IHiWC). We describe the architecture of IHiWC and present a number of new techniques that went into its design, approach and implementation. We also present results from experiments we conducted to test and validate our techniques.
