Web structure based Web search is a process of using the
hyperlink structure of the Web as an information source. The
area of Web mining focuses on the knowledge issues on
Web, using Web structure mining and introduced the Link
mining, as well as block-level link mining. There are two
popular algorithms HITS and PageRank, which are used for
mining the Web by utilizing its structure. It also explains that
data pre-processing is an important step in the knowledge
discovery process. Pre-processing internally depends upon
those two algorithms, for which to know about Website
structure and hit count of the page in Website [26]. Table III summarizes the various approaches for Web
structure based Web search. Most of the works are only
concentrating on link based rather than the text content.
Integration of soft computing techniques can overcome the
above problem. But this approach also has few limitations.
