Bradley Hauer, PhD

About Me

I am a post-doctoral researcher at the University of Alberta Department of Computing Science in Edmonton, Alberta, Canada. My field of research is natural language processing (NLP), the sub-field of artificial intelligence which encompasses work with human language.

More specifically, my current research is focused on computational lexical semantics (CLS), with a particular interest in multi-lingual semantic relations. CLS can be defined as NLP involving the meaning, or semantics, of words. Many important tasks such as automatic translation and question answering necessarily involve considering the meaning of words in context, and so can benefit from CLS research. Word sense disambiguation (WSD), the task of automatically determining the meaning of a word in context, is the central task of CLS, and remains a popular subject of research.

Specific subjects I am interested in include:

• Word sense disambiguation, related tasks, and their applications.
• Semantic knowledge bases, such as wordnets (e.g. Princeton WordNet, BabelNet).
• Applying translation and multilingual knowledge to semantic tasks.
• Theoretical models of lexical semantics.
• Analysis of semantic tasks.

My PhD thesis, "Toward a Concept-Based Theory of Lexical Semantics" can be found here.
