Abstract:Traditional approaches to plan representation focused on the generation of a sequence of actions and orderings. Knowledge rich models, which incorporate plan rationale, provide benefits to the planning process in a number of ways. The use of rationale in planning is reviewed in terms of causality, dependencies, and decisions. Each dimension addresses practical issues in the planning process and adds values to the resultant plan. The contribution of this paper is to explore this categorisation and to motivate the need to explicitly record and represent rationale knowledge for situated, mixed-initiative planning systems.
