Disambiguation based on sense definitions
(Lesk, 1986: Idea): a word’s dictionary definitions are likely to be good indicators for the sense they define.
Express the dictionary sub-definitions of the ambiguous word as sets of bag-of-words and the words occurring in the context of the ambiguous word as single bags-of-words emanating from its dictionary definitions (all pooled together).
Disambiguate the ambiguous word by choosing the sub-definition of the ambiguous word that has the greatest overlap with the words occurring in its . context.
