EVALUATION OF THE PAGERANK ALGORITHM EFFECTIVENESS

In this paper the challenges in building good search engines are discussed. Many of the search engines use well-known information retrieval algorithms and tech-niques. They use Web crawlers to maintain their index databases amortizing the cost of crawling and indexing over the millions of queries received by them. Web crawl-ers are programs that exploit the graph structure of the Web to move from page to page. Paper analyses the PageRank algorithm one of these Web crawlers. The results of the impact of the PageRank parameter value on the effectiveness of determining the so-called PageRank vector are considered in the paper. Investigations are illus-trated by means of the results of a some simulation experiments to analyze the Pag-eRank algorithm efficiency for different density graph (representing analyzed part of www) coefficient values
