Jun Chen


Jun Chen (chenjun2013@ruc.edu.cn) is a Ph.D. candidate of School of Information, Renmin University of China. He is actively participating the research activities in Database and Intelligent Information Retrieval Laboratory (DBIIR) group.

He is working on key techniques of knowledge exploration under the supervision of Pro. Xiaoyong Du and A/Prof. Yueguo Chen.

He is currently visiting Department of Computer Science, University of Helsinki as a joint training student, working on the user interface design of large knowledge graph exploration with Prof. Giulio Jacucci.



I am highly interested in how to interact with large-scale data, and improve the usability and efficiency of information exploitation and exploration. In particular, I have been playing actively in:

1) Algorithm of information search & recommendation.

2) Design of user interface.

3) Implementation of information system.

My research topics includes:

1) Exploration search

2) Information Retrieval

3) Big Data Management

4) Semantic Web
