Existing solutions to POI retrieval mainly retrieve and rank POIs based on their semantic similarity scores. Although intuitive, quantifying the relevance of a Query-POI pair by single-field semantic similarity is subject to inherent limitations. In this paper, we propose a novel Query-POI relevance model for effective POI retrieval for ondemand ride-hailing services. Different from existing relevance models, we capture and represent multi-field and local&global semantic features of a Query-POI pair to measure the semantic similarity. Besides, we observe a hidden correlation between origin-destination locations in ride-hailing scenarios, and propose two location embeddings to characterize the specific correlation. By incorporating the geographic correlation with the semantic similarity, our model achieves better performance in POI ranking. Experimental results on two real-world click-through datasets demonstrate the improvements of our model over state-of-the-art methods.</p>}, number={01}, journal={Proceedings of the AAAI Conference on Artificial Intelligence}, author={Zhao, Ji and Peng, Dan and Wu, Chuhan and Chen, Huan and Yu, Meiyu and Zheng, Wanji and Ma, Li and Chai, Hua and Ye, Jieping and Qie, Xiaohu}, year={2019}, month={Jul.}, pages={1270-1277} }
