Grounding Natural Language Semantics in Perception

   Abstract

We are developing systems that learn to converse about what they perceive and do. At the heart of our effort are two complementary goals. First, we are creating linguistically-motivated models of perception that provide the foundation of word meaning and natural language grammar. Second, we are developing language acquisition algorithms that learn linguistic structures anchored in perception and motor control. I will present recent results in word and grammar acquisition leading to perceptually-grounded spoken language generation and understanding systems. Applications include spoken language interfaces to robots, automated verbal descriptions of electronic documents, video content retrieval by natural language query, and a variety of other multimodal human-machine interfaces.
