The selection of features is critical in providing discriminative information for classifiers in Word Sense Disambiguation (WSD). Uninformative features will degrade the performance of classifiers. Based on the strong evidence that an ambiguous word expresses a unique sense in a given collocation, this paper reports our experiments on automatic WSD using collocation as local features based on the corpus extracted from People’s Daily News (PDN) as well as the standard SENSEVAL-3 data set.

Key Quantitative Results

  • The average precision on the PDN corpus has 3.2% improvement compared to 81.5% of the baseline system where collocation features are not considered. For the SENSEVAL-3 data, we have reached the precision rate of 37.6% by integrating collocation features into contextual features, to achieve 37% improvement over 26.7% of precision in the baseline system.
