Kun Zhang, Ph.D., Associate Professor and Doctoral Supervisor of Hefei University of Technology. His main research interests include research in the fields of text semantic understanding, semantic matching, semantic reasoning, text-based recommender systems, etc. He has published more than 20 papers in top conferences such as SIGIR, WWW, ACL, AAAI, and ICDM, as well as top journals including TSMC-S, TNNLS, and TKDE. He was selected for the 2021 Microsoft Research Asia Cast Star Scholars Programme, won the KDD2018 Best Student Paper Award, and served as a program committee member of international conferences such as SIGIR, ACL, AAAI, EMNLP, and so on. 

For his research, he has proposed a dynamic attention mechanism incorporating a priori knowledge of users' reading habits, which achieves dynamic attention to text focus content during semantic reasoning, significantly better than existing attention mechanism methods. The results were published in AAAI [1], the top academic conference in the field of Artificial Intelligence; He has proposed a multimodal graph modeling method incorporating user attribute information (age, occupation, etc.), which achieves the modelling of user preferences using attribute information, and better solves the cold-start problem in the recommendation system under the premise of guaranteeing the recommendation effect. The results were published in SIGIR [2], the top academic conference in the field of information retrieval.
