In collaborative planning activities, since the agents are autonomous and heterogeneous, it is inevitable that conflicts arise in their beliefs during the planning process. In cases where such conflicts are relevant to the t~t~k at hand, the agents should engage in collaborative negotiation as an attempt to square away the discrepancies in their beliefs. This paper presents a computational strategy for detecting conflicts regarding proposed beliefs and for engaging in collaborative negotiation to resolve the conflicts that warrant resolution. Our model is capable of selecting the most effective aspect to address in its pursuit of conflict resolution in cases. | Response Generation in Collaborative Negotiation Jennifer Chu-Carroll and Sandra Carberry Department of Computer and Information Sciences University of Delaware Newark DE 19716 USA E-mail jchu Carberry @ Abstract In collaborative planning activities since the agents are autonomous and heterogeneous it is inevitable that conflicts arise in their beliefs during the planning process. In cases where such conflicts are relevant to the task at hand the agents should engage in collaborative negotiation as an attempt to square away the discrepancies in theữ beliefs. This paper presents a computational strategy for detecting conflicts regarding proposed beliefs and for engaging in collaborative negotiation to resolve the conflicts that warrant resolution. Our model is capable of selecting the most effective aspect to address in its pursuit of conflict resolution in cases where multiple conflicts arise and of selecting appropriate evidence to justify the need for such modification. Furthermore by capturing the negotiation process in a recursive Propose-Evaluate-Modify cycle of actions our model can successfully handle embedded negotiation subdialogues. 1 Introduction In collaborative consultation dialogues the consultant and the executing agent collaborate on developing a plan to achieve the executing agent s domain goal. Since agents are autonomous and heterogeneous it is inevitable that conflicts in their beliefs arise during the planning process. In such cases collaborative agents should attempt to square away Joshi 1982 the conflicts by engaging in collaborative negotiation to determine what should constitute their shared plan of actions and shared beliefs. Collaborative negotiation differs from non-collaborative negotiation and argumentation mainly in the attitude of the participants since collaborative agents are not selfcentered but act in a way as to benefit the agents as This material is based upon work supported by the National Science Foundation under
