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.; [[ [TKDE 2023|https://doi.org/10.1109/TKDE.2021.3095309], [SIGIR 2022|https://doi.org/10.1145/3477495.3531729], [ISWC 2021|https://doi.org/10.1007/978-3-030-88361-4_1] ]
* __knowledge graph search__: search algorithms for large knowledge graphs, e.g., efficient approximation algorithms for Steiner Tree problems; [[ WWW 2023, [WWW 2021|https://doi.org/10.1145/3442381.3449900], [IJCAI 2021|https://doi.org/10.24963/ijcai.2021/215] ]
* __complex question answering__: neuro-symbolic methods for question answering with applications to complex tasks such as problem solving.
