Guohui Xiao is an assistant professor at the KRDB Research Centre
for Knowledge and Data, Faculty of Computer Science at Free University of
Guohui's current research focuses on Virtual Knowledge Graphs (VKGs), also known as Ontology-base
Data Access (OBDA).
His interests include theoretical investigation, system implementation, and industrial use-cases of VKG/OBDA
He is leading the development team of
Ontop VKG system, which has been adopted in many academic and industrial
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.
