This research introduces IntentPOI, a two-stage framework that decouples intention inference from direct location prediction to mitigate shallow correlations and historical bias in LLM-based POI forecasting. By explicitly modeling intermediate traveling intentions before selecting specific points of interest, the approach consistently outperforms eleven state-of-the-art baselines across multiple real-world datasets. The method represents a significant architectural shift from trajectory matching to intention-guided reasoning for next POI prediction tasks.
Think Before You Act: Intention-Guided Reasoning for LLM-Based Location Prediction
arXiv:2606.08122v1 Announce Type: new Abstract: Predicting a user's next Point-of-Interest (POI) based on their historical check-in records is a fundamental task in location-based services. While recent methods incorporating large language models have shown strong reasoning capabilities and promising results, they typically formulate the prediction task as a one-step trajectory-to-location mapping problem, making predictions prone to shallow trajectory correlations and historical frequency bias. We argue that users rarely choose locations directly and instead, they usually first form a traveling intention and then accordingly select specific POIs. Motivated by this insight, we propose IntentPOI, a two-stage intention-guided reasoning framework. In the thinking stage, we infer users' intermediate intentions by incorporating historical mobility patterns, similar peer behaviors, and the temporal contexts. In the acting stage, we first construct a compact candidate pool, and then perform intention-guided reasoning to identify locations that best align with the inferred intention. By explicitly decoupling intention inference from location prediction, IntentPOI transforms the next POI prediction from direct trajectory matching into intention-guided reasoning. Extensive experiments on three real-world datasets demonstrate that IntentPOI consistently outperforms eleven state-of-the-art baselines.
