A A NEW NEW MODEL MODEL FOR FOR AUTOMATIC AUTOMATIC GENERATION GENERATION OF OF PLAN PLAN LIBRARIES LIBRARIES FOR FOR PLAN PLAN RECOGNITION RECOGNITION

The problem of generating plan libraries for plan recognition (the inverse of the planning problem), has gained much importance in recent years, because of the dependence of the existing plan recognition techniques on them, and the difficulty of the problem. Even when there is considerable work related to the plan recognition process itself, less work has been done on the generation of such plan libraries. In this paper, we present some preliminary ideas for a new approach for acquiring hierarchical plan libraries automatically, based only on a few simple assumptions and with little given knowledge.
