Guohui is a professor at School of Computer Science and Engineering, Southeast University (SEU), China.
Before joining SEU, Guohui was an associate professor at the Department of Information Science
and Media Studies,
Faculty of Social Sciences
at University of Bergen (UiB), Norway;
and worked as an assistant professor at the KRDB Research
Centre
for Knowledge and Data, Faculty of Computer Science at Free University of
Bozen-Bolzano.
He obtained his PhD degree in Vienna University of Technology and his MSc and BSc degrees in Peking University.
Guohui's primary research interest is Knowledge Engineering, combining techniques from multiple fields: Knowledge Representation, Knowledge Graphs, Machine Learning, Natural Language Processing, and Large Language Models.
His research covers all aspects of Knowledge Engineering, including theoretical investigation, system implementation, and industrial use cases.
One special focus is Virtual Knowledge Graphs (VKGs), also known as Ontology-base
Data Access (OBDA).
He is leading the development team of
Ontop VKG system, which has been adopted in many academic and industrial
projects.
Guohui is a co-founder of the Ontopic startup, whose mission is to bring the VKG technology to industry. Ontopic is the first spin-off of the Free University of Bozen-Bolzano. Within Ontopic, he covers the position of Chief Scientist.
