Topic

Natural language is a powerful and intuitive modality for enabling humans to interact with physical systems. Understanding language about physical systems requires the ability to extract a semantically meaningful representation from the language and map it to aspects of the external world. This problem, referred to as the language grounding problem, has received substantial attention recently, in part because advances in robotics and sensing technology have enabled more robust sensing, manipulation, and simulation of the physical world, and in part as a result of recent advances in natural language processing and formal representation systems.

The AAAI-12 Workshop on Grounding Language for Physical Systems aims to bring together different communities considering the language grounding problem, including natural language understanding, spatial cognition, knowledge representation, computer vision, and robotics. The workshop will provide a venue to discuss shared problems, describe key research problems and challenges, and make progress towards formulating shared definitions.

The following topics are of particular interest:

  • Definitions of and possible approaches to the language grounding problem.
  • Methods and models for mapping between language and the external world.
  • Interactive physical systems that can be used in exploring the grounding problem, including robots, sensors, and physically interactive systems.
  • Knowledge representations that support a range of semantic constructions, such as ambiguity and reference.
  • Algorithms for learning grounded meanings from gesture, language, and other input types.
  • Interpreting instructions for physically-grounded perceptual or manipulative tasks.
  • Vision, haptics, audio, and other sensing modalities for grounding linguistic elements such as attributes, objects, tasks, and spatial relationships.
  • Challenge problems in the grounding space.

Schedule

The workshop will consist of six talks, a poster session in which accepted authors will present their work, and a discussion period. The emphasis will be on discussion and interaction among the participants.
