Researchers have developed SemPOI-RL, a new framework designed to improve the semantic reasoning and sequential generation capabilities of large language models (LLMs) for out-of-town Point of Interest (POI) recommendations. This framework addresses the challenge of adapting LLMs to cross-city interest drift and generating coherent travel trajectories by inferring travel styles from user hometown behaviors. SemPOI-RL utilizes a Semantic POI Alignment Module (SPAM) to ground these inferred styles into position-aware trajectory generation and employs reinforcement learning to optimize style alignment with downstream sequence quality. Experiments demonstrate that SemPOI-RL surpasses traditional recommenders and direct LLM baselines, offering interpretable style attribution. AI
