Mining Contents in Web Pages and Ranking of Web Pages Using Cosine Similarity

Divya C.

Abstract: Now a days internet has become a part of life because of which web pages have became a key communication and information medium for various organizations. Web pages typically contain a large amount of information that is not part of the main contents of the pages, e. g. ; banner ads, navigation bars, copy right and privacy notices, advertisements which are not related to the main content (relevant information). In this paper the system use HTML Parser to construct DOM (Document Object Model) tree from which Content Structure Tree (CST) is constructed which can easily separate the main content blocks from the other blocks. The paper also introduces a method for calculating the rank of a web page based on the content similarity between the web documents and the user query, since usually when the user searches for web pages using a key word many web pages are retrieved the user might not be knowing which web pages are most relevant to overcome this problem the web pages are ranked using Cosine Similarity and Jaccard Similarity. The Cosine Similarity and Jaccard Similarity are implemented with the stop word removal algorithm. Many experiments were conducted for both Cosine Similarity and Jaccard Similarity. The obtained results have been compared to decide which one work best. The result was that Cosine Similarity retrieved most relevant pages to the user than the Jaccard Similarity.
