In my research, I want to help computers understand the meaning of words and utterances, and perform operations that we, humans, perform with language such as logical inference and translation. I want to help them recognize that one cannot run and sleep at the same time; that cats are pets but so can be iguanas; that a great movie is one I would recommend to a friend, and this in different languages. My main research fields are Computational Linguistics and Natural Language Processing. I am interested in theoretical and application-oriented aspects of natural language semantics, and in cognitive aspects of language learning. I currently work as Senior Researcher in the Language Technology lab at the University of Helsinki, Department of Digital Humanities, on leave from the French CNRS where I hold a tenure position. I am also adjunct faculty member in the Computer and Information Science Department at the University of Pennsylvania, Philadelphia. I am an Associate Researcher in the NLP group of the Department of Informatics at the Athens University of Economics and Business.
