It is fascinating that by producing a sequence of sounds, gestures, or written symbols people can successfully communicate highly complex ideas and subtle feelings. How does that work?

Linguists, philosophers, cognitive scientists, and computer scientists have made tremendous progress in addressing this question. And insights emerging from these investigations have led to many practical applications in language technology and education.

However, more attention has been paid to certain forms of communication than to others. The truth-conditional content of declarative sentences has been investigated in much greater depth than the semantic content of other sentence types, such as questions. Spoken languages have been studied much more extensively than signed languages. My research interests center on these lesser explored forms of communication.

How should theories of meaning be generalised beyond truth-conditional content?

And what can we learn about communication by looking beyond spoken languages?

Beyond truth-conditions: inquisitive semantics

Truth-conditional semantics

It is a commonplace idea that a child has learned the meaning of a sentence like ''The book is on the table'' if it can tell whether the sentence is true or false in any given situation. This truth-conditional notion of meaning has been very fruitful but also has clear limitations. Namely, while declarative sentences can be judged true or false in a given situation, this does not hold for other types of sentences, such as questions.

Inquisitive semantics

Generalising the truth-conditional notion of meaning to overcome this limitation has been one of the main aims of my work over the last ten years. Together with several colleagues and students, I have developed a semantic framework called inquisitive semantics, which is based on a more general notion of meaning. This 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.

Collaborators and students

I'm working on inquisitive semantics and related topics with many wonderful colleagues and students. I also maintain an online portal on inquisitive semantics, where you can find publications, courses, workshops, resources and a list of inquisitive semantics researchers and projects around the world.

Beyond spoken languages

Sign language: linguistic structure made visible

Investigating sign languages has the potential to yield important linguistic insights which are much more difficult to obtain by investigating spoken languages alone, because linguistic structures are sometimes much easier to detect in sign languages than in spoken languages. Quite literally, sign languages often make linguistic structure directly visible.

Breaking language barriers

Not only can science benefit from investigating sign languages; it also has an important role to play in diminishing the language barriers between deaf and hearing people. Deeper insights into the grammar of sign languages are essential in training sign language interpreters and to lay a solid foundation for sign language machine translation technology.

SignLab Amsterdam

At the recently founded SignLab Amsterdam we are pursuing deeper insights into sign language grammar, and are using these insights to develop machine translation tools that can translate sentences from Dutch or English into Sign Language of the Netherlands (NGT), displayed by means of animated avatars.
