متن کاملLearning Plan Knowledge in Tasks with Information Gathering
In this paper we describe a framework for learning plan knowledge using expert solution traces in domains that include information-gathering tasks. We describe an extension to a special class of hierarchical task networks (HTNs) that can naturally represent information-gathering tasks and partial plans. We show how an existing analytical learning algorithm designed to learn a special form of HT...
