Abstract

In this paper we propose a general framework for word sense disambiguation using knowledge latent in Wikipedia. Specifically, we exploit the rich and growing Wikipedia corpus in order to achieve a large and robust knowledge repository consisting of keyphrases and their associated candidate topics. Keyphrases are mainly derived from Wikipedia article titles and anchor texts associated with wikilinks. The disambiguation of a given keyphrase is based on both the commonness of a candidate topic and the context-dependent relatedness where unnecessary (and potentially noisy) context information is pruned. With extensive experimental evaluations using different relatedness measures, we show that the proposed technique achieved comparable disambiguation accuracies with respect to state-of-the-art techniques, while incurring orders of magnitude less computation cost.
