Abstract:
Current Word Sense Disambiguation systems suffer from the lack of hand-tagged data, as well as performance degradation when moving to other domains. In this paper we explore three different improvements to state-of-the-art systems: 1) using Singular Value Decomposition in order to find correlations among features, trying to deal with sparsity, 2) using unlabeled data from a corpus related to the evaluation corpus, and 3) splitting the feature space into smaller, more coherent, sets. Each of the proposals improves the results, and properly combined they achieve the best results to date for the Senseval 3 lexical sample dataset. The analysis of the results provides further insights and possibilities for the future.
