In computational linguistics, word-sense disambiguation (wsd) is an open problem of natural language processing and ontologywsd is identifying which sense of a word (ie meaning) is used in a sentence, when the word has multiple meanings. This thesis introduces an innovative methodology of combining some traditional dictionary based approaches to word sense disambiguation (semantic similarity measures and overlap of word glosses, both based on wordnet) with some graph-based centrality methods, namely the degree of the vertices, pagerank, closeness, and betweenness. This thesis investigates research performed in the area of natural language processing it is the aim of this research to compare a selection of predominant word sense disambiguation algorithms, and also determine if they can be optimised by small changes to the parameters used by the algorithms.
