Learning to Mediate Perceptual Differences in Situated Human-Robot Dialogue

  title={Learning to Mediate Perceptual Differences in Situated Human-Robot Dialogue},
  author={Changsong Liu and Joyce Yue Chai},
In human-robot dialogue, although a robot and its human partner are co-present in a shared environment, they have significantly mismatched perceptual capabilities (e.g., recognizing objects in the surroundings). When a shared perceptual basis is missing, it becomes difficult for the robot to identify referents in the physical world that are referred to by the human (i.e., a problem of referential grounding). To overcome this problem, we have developed an optimization based approach that allows… CONTINUE READING
