Plan Recognition

Aliases: Plan Inference

Keywords: matching

Categories: Natural Language , Planning

Author(s): Jim Doran

Given a sequence of actions carried out in a task domain by some actor, it is possible to draw conclusions about the plan that the actor is executing by working bottom up. If the actor's top goal is known or can be guessed, then a top down matching process is feasible. The task of plan recognition can be related to Chart Parsing and can be partially formalised using a first order theory of action and Circumscription.
