An associative method for Lesk-based word sense disambiguation
Abstract One of the most important current problems in natural language processing is word sense disambiguation (WSD). WSD consists of identifying the correct sense of the words in a given text. In this work, we present a novel method for automatic WSD based on the simplified-Lesk algorithm. The pro...
