Rooth, Mats
Professor & Director, Comp. Li
I do research in two areas, computational linguistics and natural language semantics. I have worked extensively on mixed symbolic/probabilistic models of syntax and the lexicon, and am particularly interested in putting linguistic theories into contact with large samples of written and spoken language by means of efficient algorithms and numerical modeling. Currently, I am working on probabilistic parse forest algorithms which detect isolated linguistic events, such as one word being the head of an argument of another word. In semantics, I have worked on contrastive intonation (what is called focus), and on related phenomena such as ellipsis and presupposition.
