Abstract: We introduce a method for word sense disambiguation that uses an existing topical document map crated with an unsupervised method (WEBSOM) on a very large document collection. Results on the SENSEVAL-2 corpus indicate that the method is statistically significantly better than the baselins and on par with supervised methods. The method uses the document map as a representation of the semantic space of word contexts. The assumption is that similar meanings of a word have similar contexts, which are located in the same are on the self-organized document map. The results confirm this assumption. The benefi of the proposed method is that a single general purpose representation of the semantic space can be used for all words and their word senses.
