We report the initial results of a word-sense disambiguation experiment which aims at identifying the correct sense of Swedish nouns and verbs in a sentence using a lexical-semantic resource, SALDO. This resource containing associations between word senses has not been previously used for this purpose. The proposed method is based on overlaps between a list of hierarchically organized related word senses. Overall, our approach proved more efficient for nouns, since not only was the accuracy score higher for nouns (56%) than for verbs (46%), but, for the former category, in 22% more of the cases was a sense overlap found. As a result of an in-depth analysis of the predictions, we identified a number of ways the system could be modified or extended for an improved performance.
