Title: Genteel-Negotiator: LLM-enhanced mixture-of-expert-based reinforcement learning approach for polite negotiation dialogue Teams link to connect online
Abstract:
Developing intelligent negotiation dialogue systems that promote fair and sustainable outcomes is crucial for advancing automated negotiation for social good. Since effective negotiation requires balancing cooperation and competition while maintaining respect, we propose GENTEEL-NEGOTIATOR, a polite negotiation dialogue system for tourism and e-commerce domains. We introduce NEGOCHAT, a tourism negotiation dataset, and enrich it along with the Integrative Negotiation Dataset (IND) using diverse negotiation strategies. Built on an LLM-enhanced Mixture-of-Experts reinforcement learning framework, the model incorporates dedicated experts for negotiation, politeness, and coherence, guided by a reward function capturing strategy alignment, politeness, coherence, and engagingness. Extensive automatic and human evaluations demonstrate its effectiveness in generating polite, coherent, and goal-oriented negotiation responses.
