Acquisition of User Preferences for Plan Recognition
نویسنده
چکیده
Plan recognition systems need a measure to assess the quality of their hypotheses about a user’s goals. Such a measure allows the exclusion of extremely “bad” hypotheses at an early stage or the selection of the “best” one whenever this is required, e.g. when a help system is asked to provide support to the user of an application system. To work properly, such a measure has to take into account the user’s individual preferences and particularities. This paper presents an approach to the acquisition of such user preferences in noncooperative domains and their exploitation in the assessment of the hypotheses of a plan recognizer.
