Biography

Dr. Jiaoyan Chen is a Senior Researcher at Department of Computer Science, University of Oxford and a member of Data and Knowledge Group, reporting to Prof. Ian Horrocks. He was previously a PostDoctoral Researcher in GIScience in Heidelberg University. Jiaoyan got his Ph.D in Computer Science and Technology in Zhejiang University, supervised by Prof. Zhaohui Wu and Prof. Huajun Chen. He was also a visiting student of Zurich University, supervised by Prof. Daning Hu. Jiaoyan got his Bachelor degree in Computer Science and Technology in Zhejiang University.

Research Interest

Knowledge Graph, Semantic Web, Transfer and Zero-shot Learning, Neuro-Symbolic AI

Ongoing Projects

• Jiaoyan is now working on knowledge graph construction and curation with a combination of semantic reasoning and deep learning techniques, including 1) ontology embedding, 2) knowledge construction from tabular data and knowledge graph integration; 3) knowledge graph curation such as completion, error detection and correction. These works are/were parts of the AIDA project of the Alan Turing Institute, the "Knowledge Graph Construction for Personalisation” project funded by Samsung Research UK, and the EPSRC "ConCur: Knowledge Graph Construction and Curation" project (EP/V050869/1). Jiaoyan is a co-PI of ConCur which was funded in 2021 with 1.1 million pounds. Jiaoyan is involved in the data science program of SIRIUS in University of Oslo in collaboration with Ernesto Jiménez-Ruiz and Erik B. Myklebus. Jiaoyan is also in active collaboration with the NLP and KG group of Tencent Jarvis Lab.
• The knowledge graph construction and curation projects involve new Neuro-Symbolic technqies for challenges such as the sample shortage and the subsymbolic representtion of logics. Jiaoyan has been working on relevant techniques including OWL ontology embedding, knowledge driven zero-shot and transfer learning, and machine learning explanation. External collaborators include Huajun Chen, Yuxia Geng and Zhuo Chen from Zhejiang University, Jeff Z. Pan from The University of Edinburgh and so on.
