Gong Cheng is a professor at the Department of Computer Science and Technology, Nanjing University. He received his PhD from Southeast University. His research interests include knowledge graph, data search, and neuro-symbolic reasoning with applications to knowledge-based hybrid intelligent systems such as open data portals, question answering systems, and AIOps platforms. His research has been published in journals and at conferences including TKDE, WWW, SIGIR, AAAI, IJCAI, ACL, ISWC, and has received or been nominated for six best paper awards. He was a Posters & Demos co-chair of ISWC 2019.
At present, his research is focused on
- open data portal: a better open data portal, featuring data fusion, retrieval, ranking, summarization, recommendation, etc.;
- knowledge graph search: search algorithms for large knowledge graphs, e.g., efficient approximation algorithms for Steiner Tree problems;
- complex question answering: neuro-symbolic methods for question answering with applications to complex tasks such as problem solving.
