🚩 About Me
I’m currently a Ph.D. Student from School of Computer Science (SCS), Beijing University of Posts and Telecommunications (BUPT), supervised by Prof. Haihong E. I visit College of Computing and Data Science (CCDS), Nanyang Technological University (NTU) as a joint Ph.D. Student in November 2024, supervised by Asst. Prof. Luu Anh Tuan. Before that, I received the bachelor degree at School of Computer Science (SCS), Beijing University of Posts and Telecommunications (BUPT) in 2021.
My research interest includes knowledge graph, large language model and their bi-directionally driven combination for interpretable representation learning and doman-specific applications, which can be devided as follow:
- Hierarchical Hyper-relational Knowledge Graph Schema Design
- LLM-based Knowledge Graph Construction
- LLM-based Semantic Parsing for Knowledge Base Question Answering
- Pretrained Model for Hyper-relational Knowledge Graph Embedding
- Complex Logical Query Answering over Knowledge Graphs
