Sense and Deduction: The Power of Peewees Applied to the SENSEVAL-2 Swedish Lexical Sample Task

This paper describes our use of Prolog Word Experts (PWEs) in the Senseval-2 competition. We explain how we specify our PWEs as sequences of transformation rules and how they can be trained on sense tagged corpus data. We give a semantics of PWEs by translating them into first order predicate logic, and we describe how PWEs can be compiled into Prolog procedures. We finally present our results for the Swedish lexical sample task: 63% (fine-grained score) for our best PWE, and a second place in the ranking.
