Situated Statistical Language Learning

Situated Statistical Language Learning
We approach the problem of how machines, and humans, can learn words that describe actions. We put forth that such words are grounded not in the sensory-motor aspect of an action, but rather in the intentions of the person performing the action. We therefore pose the problem of action-word learning in two stages: intention recognition and linguistic mapping. The first of these stages is cast as a plan-recognition problem in which state-action sequences are parsed using a probabilistic online chart parser. The second stage casts mapping in a Bayesian framework, employing algorithms used in speech recognition and machine translation.
