About Me
I am a third-year Ph.D. student of Department of Computer Science in University of Oxford. I work in the Data and Knowledge Group, advised by Prof. Bernardo Cuenca Grau, Prof. Ian Horrocks, and Dr. David Tena Cucala. Before that, I achieved my M.S. degree at Department of Computer Science and Technology in Nanjing University. I worked in Websoft Research Group, supervised by Prof. Gong Cheng and Prof. Yuzhong Qu.
My C.V. is available here.
Research Interests
My research interests include knowledge graph, neuro-symbolic reasoning, and semantic technologies applied in intelligent systems.
Currently, I focus on interpreting neural network models, especially for knowledge graph reasoning, with symbolic rules, to achieve explainable and effective systems. I have also worked on semantic search algorithms applied in dataset search systems, mainly related to data summarization, query analysis, and information retrieval.
