Tailoring the Presentation of Plans to Users’ Knowledge and Capabilities

Tailoring advice to a user means finding a plan by which she can reach her goal, and supplying the missing knowledge that she needs to successfully execute the plan. The paper presents an algorithm to determine the kind and amount of this missing knowledge for an already generated domain plan. We show that both the user's knowledge and his capabilities to perform actions must be taken into account when deciding on a plan presentation that is adequate for him. We also demonstrate that it may be useful to consider issues of plan presentation already during the planning process, and indicate how this can be accomplished in a planning system.
