Online Library Content Generation Using Focused Crawling Based Upon Meta Tags and Tf-Idf

Abstract

Electronic library is the collection of digital information related to an individual domain and in turn to all domains. A focused crawler traverses the Web looking for the pages most relevant to a domain and at the same time discarding the irrelevant pages and hence is helpful for generating the-e contents for digital library related to a particular domain. In this paper a focused crawling technique to generate online contents for e-library is proposed. The applicability of the proposed approach is shown by retrieving the documents which are highly related to a single domain. The quality of the pages included into the library is derived from the relevancy measure of the page with the content of domain related pages.
