Impacts of Keyword Frequency and Ranking Scope on Relevance of Web Search Results

In the past few decades, The World Wide Web has expanded vigorously and so has the information accessible on The Internet. In today’s world, it would be impossible to navigate through this gigantic network without the help of a modern Web Search Engine to find the relevant information. Since introduction of PageRank, many variations of it have been proposed which mainly focus on link structure of web and query context. In this work, a generalized PageRank is proposed to incorporate two important factors for quality search results; keyword frequency and ranking scope. Different variations of the proposed ranking algorithm are analyzed to establish importance of proposed factors in influencing relevance of search results with respect to keywords of interest. The experimental results show that the proposed algorithm significantly outperforms PageRank algorithm.
