Recording Rationale in <I-N-C-A> for Plan Analysis
The aim of this paper is to show how the rationale behind a plan can be recorded in the plan itself. The <I-N-C-A> model which underlies the I-X framework will be described in detail, focussing on annotations. It is there that a planner can record the justifications for including components into the plan. Recording rationale information of this type can be used for a number of purposes in the life cycle of a plan, including plan indexing and retrieval, failure recovery, plan explanation and establishing trust as explained in this paper.
