A Statistical Approach to URL-Based Web Page Clustering

Most web page classifiers use features from the page content, which means that it has to be downloaded to be classified. We propose a technique to cluster web pages by means of their URL exclusively. In contrast to other proposals, we analyse features that are outside the page, hence, we do not need to download a page to classify it. Also, it is non-supervised, requiring little intervention from the user. Fur-thermore, we do not need to crawl extensively a site to build a classifier for that site, but only a small subset of pages. We have performed an experiment over 21 highly visited web-sites to evaluate the performance of our classifier, obtaining good precision and recall results.Junta de Andalucía P08-TIC-4100Ministerio de Ciencia e Innovación TIN2010-2174
