Mats Rooth



Rooth does research in two areas, computational linguistics and natural language semantics. He has worked on mixed symbolic/probabilistic models of syntax and the lexicon, on contrastive intonation (what is called focus), and on related phenomena such as ellipsis and presupposition. In addition to these, he is currently working on finite state models of phonology and phonetics.
