WebbStanford University WebbThe Simplified Lesk Algorithm (SLA) is frequently used for word sense disambiguation. It disambiguates by calculating the overlap of a set of dictionary definitions (senses) and the context words.

Even if there is a human annotated training data, it does not learn from the data. Variations of Lesk WebbThis paper describes a new Word Sense Disambiguation (WSD) algorithm which extends two well-known variations of the Lesk WSD method. Given a word and its context, Lesk algorithm exploits the idea of maximum number of shared words (maximum overlaps) between the context …

Webb10 apr. 2016 · The Simplified Lesk algorithm, in trying to disambiguate the meaning of a word in a given sentence does the following: context <- all the words except the target word from the sentence. signature <- words appearing in the dictionary definition of target word + any words appearing in the examples used to illustrate usage of the word. Webbhe Simplified Lesk Algorithm is frequently employed for word sense disambiguation. It disambiguates through the intersection of a set of dictionary definitions (senses) and a set of words extracted of the current context (window). However, the Simplified Lesk Algorithm has a low performance.
