A Survey on Word Sense Disambiguation

Abstract

In natural language processing (NLP), word sense disambiguation (WSD) is an automatic process carried out by a machine to sense the appropriate meaning of a word in a particular context or in a discourse. Natural language is ambiguous, so that many words may be interpreted in multiple methods depending on the context wherein they occur. The computational identification of which means for words in context is known as word sense disambiguation (WSD). In this paper, we will discuss the ambiguity of the words in the languages and the essential measures to deal with the ambiguous words.

Keywords: ambiguity, word discrimination, supervised ambiguity, unsupervised ambiguity.

1. Introduction

Word sense disambiguation is a necessary leap for many language translation applications for major human languages spoken across the world. It provides inspiration and motivation to many international research organizations to work on word sense disambiguation. As till date, no accurate system has been developed for WSD [1] which could achieve the current state-of-the-art accuracy rate of 60-70%. Though, WSD is a most significant problem in natural language processing most of the approaches and techniques presented till date to tackle WSD are not stand-alone techniques. To carry out the word sense disambiguation we are in a need of a very large amount of word knowledge. Ambiguity in language means words that carry multiple meanings in different settings and also changes the way the same sentence is interpreted.
