Maryam Hazman · Journal of Global Research in Computer Sciences · 2012
As a result of the rapid growth of the World Wide Web contents, the focused challenges are increasing. The problem that focused crawlers deal with is to selectively download relevant pages from the World Wide Web. In this paper, we present a survey for the different approaches in focused crawler which we classify them into three categories. Ontology based focused crawlers depend on ontology to determine the relevant pages. Structure base focused crawlers take in accounting the web pages structure when evaluating the page relevance. Other focused crawlers have their own features that cannot be categorized to one of the previously focused crawlers approached.
