AI Tour Meeting: Group Travel Planning by LLM Agents

Daisuke Kikuta presented AI Tour Meeting, a framework in which multiple LLM-based agents with distinct personas negotiate a group travel itinerary through natural-language discussion, at AACL-IJCNLP 2026 in Hengqin, China, published as pages 58–65 of the System Demonstrations proceedings. The framework provides interfaces for configuring agent personas, discussion workflows, monitoring and LLM deployment, and is positioned primarily as a simulation tool for analyzing multi-agent behavior during tour planning. The paper reports system validation and several analytical results obtained with the framework.

Abstract This paper proposes AI Tour Meeting, a group travel planning framework powered by multiple Large Language Model LLM -based agents. The agents are instantiated with distinct personas and collaboratively seek an itinerary that satisfies their constraints and preferences through natural language discussion. The framework enables easy and flexible orchestration of such discussions by providing interfaces for configuring agent personas, discussion workflows, monitoring, and LLM deployment. Its primary use case is a simulation tool for analyzing the behavior of multiple LLM agents during tour planning discussions. This paper demonstrates the utility of the framework by presenting system validation and several analytical results obtained using the framework. - Anthology ID: - 2026.aacl-demo.8 - Volume: - Proceedings of the 15th International Joint Conference on Natural Language Processing and the 5th Conference of the Asia-Pacific Chapter of the Association for Computational Linguistics: System Demonstrations https://aclanthology.org/volumes/2026.aacl-demo/ - Month: - November - Year: - 2026 - Address: - Hengqin, China - Editors: - Ningyu Zhang https://aclanthology.org/people/ningyu-zhang/ , Derry Wijaya https://aclanthology.org/people/derry-tanti-wijaya/ - Venues: - AACL https://aclanthology.org/venues/aacl/ | IJCNLP https://aclanthology.org/venues/ijcnlp/ - SIG: - Publisher: - Association for Computational Linguistics - Note: - Pages: - 58–65 - Language: - URL: - https://aclanthology.org/2026.aacl-demo.8/ https://aclanthology.org/2026.aacl-demo.8/ - DOI: - Cite ACL : - Daisuke Kikuta. 2026.
