Research summary: In the field of Knowledge Engineering and Expert System, the team focuses on the theory and technology of uncertainty reasoning, cooperation methods of multi-expert systems, learning and reasoning of Bayesian Network, knowledge base refinement, Multi-evidence fusion and multi-methods integration. In the field of Spatio-temporal Knowledge Processing: the team focuses on modeling of complex spatial relation, processing uncertain spatio-temporal information, spatio-temporal logic, spatio-temporal data mining, processing of spatio-temporal semantics. In the field of Data Mining and Complex Networks, the team focuses on the mining methods of complex data, like huge data, multi-source data, multi-relational data, dynamic and uncertainty data, deep combination of learning and inference, analysis methods of complex network structures and dynamic, data mining and machine learning methods for social network and social network. In the field of Distributed Artificial Intelligence and Agent Systems, the team focuses on agent systems and architectures of intelligent agent, formalized modeling of mobile agent, complex task solving based on Agent. The team is one of the teams that study the above four fields at the earliest. It promotes the level of research and application on Intelligence Reasoning and Intelligence System in China.

The team has successfully undertaken more than 50 scientific research projects at national, provincial and ministerial levels, among which "863" projects and NSFC (National Nature Science Foundation of China) projects are more than 20; published 9 books and more than 500 papers in journals and international conferences, including more than 300 SCI and EI cited articles. The research had won one second prize and one third prizes of the National S&T Progress Award, four first prizes, four second prizes, and three third prizes of the Provincial and ministerial S&T progress Award, two first prizes of the Changchun City S&T Progress Award, two national patents, one second Prize of State-level Teaching Award, two first Prizes of Province-level Teaching Award, one second prize of Ministry-level Award for Excellent Textbook of Colleges and Universities. The team is also awarded the National Top Quality Course, the National Top Quality Resource-Sharing Course, and outstanding team in educational system of Jilin Province.
