We consider a Web page expansion by using text content of it's linking pages. We show that naive expansion can grab too much noise and essentially harm categorization results. We present the approach to automated pruning of linking Web pages. We report that using our approach in forming a Web page representation always leads to better results than traditional single Web page categorization.enText/Conference Paper1617-5468
