Graeme Hirst's research interests cover a range of topics in computational linguistics and natural language processing, including lexical semantics, the resolution of ambiguity in text, the analysis of authors' styles in literature and other text (including plagiarism detection and the detection of online sexual predators), and the automatic analysis of arguments and discourse. His present research includes the problem of near-synonymy in lexical choice in language generation; detecting markers of Alzheimer's disease in the works of literary writers; and applications of lexical chaining as an indicator of semantic distance in texts.
Hirst is the editor of the Synthesis series of books on Human Language Technologies. He is the author of two monographs: Anaphora in Natural Language Understanding and Semantic Interpretation and the Resolution of Ambiguity. He is the recipient of two awards for excellence in teaching. He has supervised more than 35 theses and dissertations, four of which have been published as books. He was elected Chair of the North American Chapter of the Association for Computational Linguistics for 2004-05 and Treasurer of the Association for 2008-2017.
