Detecting and Responding to Plan-Oriented Misconceptions

This chapter2 discusses the problem of detecting and responding to plan-oriented misconceptions in advice-seeking dialogs, concentrating on the problems of novice computer users. A cooperative response is one which not only corrects the user’s mistaken belief but also addresses the missing or mistaken user beliefs that led to it. Providing a cooperative response is presented as a process of the advisor trying to explain why he doesn’t hold the user’s belief and presenting this explanation to the user. An explanation is shown to correspond to a set of advisor beliefs that together contradict the user’s belief, and searching for an explanation to determine whether various abstract configurations of advisor beliefs hold. The search for an explanation makes use of both domain-specific advisor beliefs and a taxonomy of domain-independent explanations for potential user misconceptions. A taxonomy for misconceptions involving plan applicability conditions, preconditions, and effects is presented, along with a method of organizing the necessary advisor planning knowledge.
