Named entity disambiguation has been one of the main challenges to research in Information Extraction and development of Semantic Web. Therefore, it has attracted much research effort, with various methods introduced for different domains, scopes, and purposes. In this paper, we propose a new approach that is not limited to some entity classes and does http://www.sunglasses-raybans.com/ not require well structured texts. The novelty is that it exploits relations between co occurring entities in a text as defined in a knowledge base for disambiguation. Combined with class weighting and coreference resolution, our knowledge based method outperforms KIM system in this problem. Implemented algorithms and conducted experiments for the method are presented and discussed.Bekkerman, R., McCallum, A.: Disambiguating Web Appearances of People in a Social Network.
