Task: Summarization
Input (English): In this paper, I discuss some varieties of explanation that can arise
 in intelligent agents. I distinguish between process accounts, which
 address the detailed decisions made during heuristic search, and
 preference accounts, which clarify the ordering of alternatives
 independent of how they were generated. I also hypothesize 
 which types of users will appreciate which types of explanation.
 In addition, I discuss three facets of multi-step decision making
 -- conceptual inference, plan generation, and plan execution --
 in which explanations can arise. I also consider alternative ways
 to present questions to agents and for them provide their answers.

Output (English): This position paper analyzes different types of self explanation that can arise in planning and related systems.
