Pengyu Zhang 张鹏宇

Welcome to Pengyu Zhang’s Personal Homepage!

Background: I am a second-year Ph.D. student at the Informatics Institute of the University of Amsterdam (UvA) and a member of the INDE lab, where I am supervised by Prof. Paul Groth. Before joining UvA, I obtained my master’s degree from the Faculty of Information Technology at Beijing University of Technology (BJUT).

Research Interests: My research primarily focuses on enhancing Temporal Knowledge Graphs (TKGs) to better capture the dynamic nature of real-world entities and their relationships over time. I am particularly interested in integrating structural and textual information to improve entity linking and address the issue of temporal degradation. Feel free to reach out if you have any questions or would like to discuss further.
