How do people communicate? How do they decode the meaning of complex linguistic expressions? This question has been approached from many different angles in several scientific disciplines, ranging from linguistics and philosophy to logic and cognitive science. And these theoretical investigations have led to many practical applications in computer science and education.

At the heart of this enterprise is a simple notion of meaning as truth-conditional content: you know what a sentence means if you can tell when it's true and when it's false. This conception of meaning, however, has a fundamental limitation: while suitable for statements, it does not straightforwardly apply to other sentence types, like questions. After all, it does not make sense to say of a question that it is true or false.

The main aim of my work over the last ten years has been to overcome this limitation. Together with several colleagues, I have developed a semantic framework called inquisitive semantics, which is based on a more general notion of meaning and opens up new horizons for all disciplines concerned with linguistic interpretation. We are currently exploring these horizons in linguistics, logic, and philosophy, and are also looking toward applications in computer science.

My work is currently supported by a VIDI grant from the Netherlands Organization for Scientific Research (2015-2020) and a Starting Grant from the European Research Council (2016-2021).

The publication list below is generated by bibbase.org . You can search or select categories to find your way to specific types of publications. Search keywords and selected categories are interpreted conjunctively. For instance, if you search for "Ciardelli" while setting Publication type to "Journal articles" and Empirical topic to "Modality", you get all journal articles on modality co-authored with Ivano Ciardelli.
Thanks to Emmanuel Chemla and Thom van Gessel for help with building this part of the website.
