Word sense disambiguation for lexical semantics – Complete Phd and Masters Thesis

[ad_1]

Introduction:

Word sense disambiguation (WSD) is a crucial task in the field of lexical semantics, with the objective of determining the correct sense of a word within a given context. The ambiguity of natural language poses a significant challenge in understanding and processing text, leading to errors in applications such as machine translation, information retrieval, and text mining. WSD plays a vital role in improving the accuracy of these applications by disambiguating the various senses of ambiguous words.

This thesis aims to explore and analyze various methods and techniques for performing WSD, with a focus on leveraging computational linguistics and artificial intelligence. The study will investigate the latest advancements in WSD algorithms and evaluate their effectiveness in disambiguating word senses in different contexts.
