PHI : a logic-based tool for intelligent help systems
Bauer, Mathias, Susanne Biundo, Dietmar Dengler, Jana Koehler, Gabriele Paul · 1992
We introduce a logic-based system which improves the performance of intelligent help systems by supplying them with plan generation and plan recognition components. Both components work in close mutual cooperation. There are two modes of cross-talk between them, one where plan recognition is done on the basis of abstract plans provided by the planner and the other where optimal plans are generated based on recognition results. The examples which are presented are taken from an operating system domain, namely from the unix mail domain. 1 Introduction Intelligent help systems aim at providing advanced active help to the users of complex software systems (cf. [ Breuker, 1990; Thies and Berger, 1992; Norvig et al., 1993 ] ). The performance of these help systems can be considerably improved if they are supplied with plan recognition and plan generation capabilities. Observing a user and recognizing his goals enables the system to help by taking into account the current state of the syst...
