3 Adopting Domain Knowledge to Enhance Lexical Chain for Unsupervised Word Sense Disambiguation

This paper represents an idea of integrating approaches for disambiguating the word sense of a text. It combines two knowledge sources of Word Sense Disambiguation (WSD) approaches so that a better approach to be introduced to WSD research area. The Lexical Chain approach will be adopted together with the Domain knowledge to define word meaning. In order to show the efficiency of the adopting another approach, the Lexical Chain approach will be discussed in details so that the weakness of this approach could be covered by adopting the domain knowledge. The result proved that by adopting the domain knowledge into Lexical Chain approach increased the performance.
