The RHET Plan Recognition System Version 1.0

Abstract

RPRS (RHET Plan Recognition System) is a hierarchical plan recognition system built within the RHET knowledge representation system. It provides a powerful system for plan recognition based on the algorithms of Kautz(Kautz, 1987), with the general reasoning capabilities of RHET. RPRS takes special advantage of Rhet's type relations, constraints, equality and contextual reasoning abilities. RPRS is also intended as a demonstration of the Rhet programming and knowledge representation system's hybrid reasoning capabilities. Utilizing the lisp interface to Rhet, RPRS allows the user to use the Rhet structured type system to build plan types, and given some observation or set of observations have Rhet derive the set of plans that are consistent with these observations. Since RPRS includes the TEMPOS specialized reasoner for Rhet, steps and observations can have reference to time-intervals, and/or be temporally constrained with respect to one another. (kr)
