Learning Structures to Represent Verb Meaning

Sharon Salveter

A program that learns structures that represent verb meaning is described. Inputs are combinations of surface sentences and environment snapshots. The program learns to associate surface verbs with conceptual dependency networks that describe the changes that occur in the environment when an action is performed.

Each process is described as well as the circumstances under which is it performed and the effects it has on the conceptual dependencies.
