b. 1957
Mats Rooth is a formal semanticist and philosopher of language at Cornell University, best known for developing alternative semantics, a framework that analyzes focus by associating expressions with sets of semantic alternatives. His work has been foundational in linking prosodic focus to discourse structure and information packaging. He has also contributed to the formal treatment of anaphora and its interaction with discourse representation.
