Word Sense Disambiguation

Word Sense Disambiguation

The goal of this research is to explore supervised and unsupervised approaches to word sense disambiguation utilizing information from the Unified Medical Language System (UMLS).

Dissertation Proposal : Accurate and Scalable Word Sense Disambiguation in the Biomedical Domain

Dissertation : Supervised and Knowledge-based Methods for Disambiguating Terms in Biomedical Text using the UMLS and MetaMap (slides)

Software

CuiTools (Coo-e Tools) is a freely available package of Perl programs for supervised word sense disambiguation (WSD) experiments. The name CuiTools comes from the Concept Unique Identifiers (CUIs) found in the Unified Medical Language System (UMLS). This package allows the user to extract features from the UMLS, such as CUIs and semantic types, as well general English features such as part-of-speech and unigram information. The package allows for experiments to be conducted with any of the machine learning algorithms in the WEKA data-mining package.
