1. A plan recognition method, implemented by a processing system, of recognizing a plan based on observed actions comprising:

  • reading the observed actions of at least one agent;

    based on the observed actions and a plan library, generating a pending set of actions that are pending execution by the agent and generating explanations for the pending actions contained in the pending set, wherein the plan library contains plans, wherein the plans stored in the plan library include typed variables, and wherein the explanations depend on the typed variables;

    computing probabilities as to the likelihood that the explanations represent at least one actual plan of the agent; and

    , recognizing at least one of the explanations as the actual plan of the agent based on the computed probabilities.
