iTIMO: LLM-Empowered Dataset for Travel Itinerary Modification

Jul 15, 2026

Researchers have introduced iTIMO, a dataset designed to address the underexplored task of travel itinerary modification. The dataset is generated by instructing large language models to perturb real-world itineraries using REPLACE, ADD, and DELETE operations, guided by intents such as popularity disruptions, spatial distance, and category diversity. The work also benchmarks state-of-the-art LLMs on this task, revealing their strengths and limitations.

Why it matters: iTIMO provides a comprehensive testbed for developing and evaluating adaptive travel recommendation systems that can handle dynamic and changing user needs.
