Research
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.
