Idea
Next-POI prediction model enhancing location recommendations with cognitive and spatio-temporal alignment.
Research Paper
Core Innovation
This paper introduces CoAST, a framework combining large language models with enriched spatial-temporal trajectory data and cognitive alignment. It uniquely integrates world knowledge and human cognitive factors into next POI prediction, surpassing traditional models that lack structured geographical and sequential mobility understanding.
Why It Matters
Accurate next POI prediction improves user engagement and satisfaction in location-based services by anticipating immediate user destinations. Incorporating cognitive factors and world knowledge tailors recommendations to real-world contexts, boosting relevance and adoption. This approach scales across diverse user profiles and environments, transforming personalized location recommendations.

Research Paper Overview
Cognitive-Aligned Spatio-Temporal Large Language Models For Next Point-of-Interest Prediction
Summary
The next POI recommendation predicts users' immediate destinations using preferences and historical check-ins, enhancing location-based services. CoAST integrates world knowledge and human cognition factors like seasons, weather, and user profiles to improve accuracy and user experience. It uses a two-stage process of knowledge acquisition and cognitive alignment, validated by offline and online experiments including deployment in AMAP's app.
