“WE AIM
TO MAKE MACHINES
UNDERSTAND LANGUAGE.”

The main purpose of language is to encode and communicate information of all sorts.

Our research focuses on semantics — the study of meaning — and how a machine can assign meaning to utterances: words, sentences and texts, as humans can do. Our work is linguistically informed and applies advanced machine learning techniques.

Understanding of language requires knowledge of language and the world, the ability to perform reasoning, and situational context.
We study how to interface language with knowledge and how to ground language in the visual world. We investigate what can be left implicit in texts, given that language and knowledge interact, allowing humans to read between the lines.

For all this, humans and machines need knowledge:

about language, the world, people, social norms and the visual world.

“How do humans acquire and exchange knowledge?”
  • KNOWLEDGE-BASED LANGUAGE PROCESSING
  • MACHINE READING COMPREHENSION
  • COMMONSENSE INFERENCE IN SOCIAL SITUATIONS
  • COMPUTATIONAL ARGUMENTATION
“And how to express thoughts in language — accurately and naturally?”
  • NATURAL LANGUAGE GENERATION
  • MEANING-BASED NLG EVALUATION METRICS
  • RECONSTRUCTING IMPLICIT KNOWLEDGE IN TEXT
“How to represent the meaning of a discourse?”
  • STRUCTURED MEANING REPRESENTATIONS
  • REPRESENTING EVENTS AND THEIR PARTICIPANTS
  • RESOLVING ANAPHORA
“How do humans communicate in a visual situation?”
  • MULTIMODAL LANGUAGE PROCESSING
  • GROUNDING LANGUAGE IN IMAGES
