Collaborative response generation in planning dialogues

A plan-based model for response generation during collaborative planning, based on a recursive Propose-Evaluate-Modify framework for modeling collaboration, is presented, which focuses on identifying strategies for content selection when the system initiates information-sharing to gather further information in order to make an informed decision about whether to accept a proposal.

Abstract

this paper, we present a plan-based model for response generation during collaborative planning, based on a recursive Propose-Evaluate-Modify framework for modeling collaboration. We focus on identifying strategies for content selection when 1) the system initiates information-sharing to gather further information in order to make an informed decision about whether to accept a proposal from the user, and 2) the system initiates collaborative negotiation to negotiate with the user to resolve a detected conflict in the user's proposal. When our model determines that information-sharing should be pursued, it selects a focus of information-sharing from among multiple uncertainties that might be addressed, chooses an appropriate information-sharing strategy, and formulates a response that initiates an information-sharing subdialogue. When our model determines that conflicts must be resolved, it selects the most effective conflicts to address in resolving disagreemen t about the user's proposal, iden tiffes appropriate jus tiffcation for the sys tem' s claims, and formulates a response that initiates a negotiation subdialogue
