TAILIEUCHUNG - Báo cáo khoa học: "RESPONDING TO USER QUERIES IN A COLLABORATIVE ENVIRONMENT*"

We propose a plan-based approach for responding to user queries in a collaborative environment. We argue that in such an environment, the system should not accept the user's query automatically, but should consider it a proposal open for negotiation. In this paper we concentrate on cases in which the system and user disagree, and discuss how this disagreement can be detected, negotiated, and how final modifications should be made to the existing plan. | RESPONDING TO USER QUERIES IN A COLLABORATIVE ENVIRONMENT Jennifer Chu Department of Computer and Information Sciences University of Delaware Newark DE 19716 USA Internet jchu@ Abstract We propose a plan-based approach for responding to user queries in a collaborative environment. We argue that in such an environment the system should not accept the user s query automatically but should consider it a proposal open for negotiation. In this paper we concentrate on cases in which the system and user disagree and discuss how this disagreement can be detected negotiated and how final modifications should be made to the existing plan. 1 Introduction In task-oriented consultation dialogues the user and expert jointly construct a plan for achieving the user s goal. In such an environment it is important that the agents agree on the domain plan being constructed and on the problem-solving actions being taken to develop it. This suggests that the participants communicate their disagreements when they arise lest the agents work on developing different plans. We are extending the dialogue understanding system in 6 to include a system that responds to the user s utterances in a collaborative manner. Each utterance by a participant constitutes a proposal intended to affect the agents shared plan. One component of our architecture the evaluator examines the user s proposal and decides whether to accept or reject it. Since the user has knowledge about his her particular circumstances and preferences that influence the domain plan and how it is constructed the evaluator must be a reactive planner that interacts with the user to obtain information used in building the evaluation meta-plan. Depending on the evaluation the system can accept or reject the proposal or suggest what it considers to be a better alternative leading to an embedded negotiation subdialogue. In addition to the evaluator our architecture consists of a goal selector an intentional planner and a .
