Evaluating the Effectiveness of Ensembles of Decision Trees in   Disambiguating Senseval Lexical Samples
  This paper presents an evaluation of an ensemble--based system that participated in the English and Spanish lexical sample tasks of Senseval-2. The system combines decision trees of unigrams, bigrams, and co--occurrences into a single classifier. The analysis is extended to include the Senseval-1 data.
