AI(Artificial Intelligence) Lab has worked for Knowledge Representation and Reasoning, Information Retrieval, Ontology Engineering, and Intelligent Agent. Presently, we focus on community computing model and its application for ubiquitous computing environment, and develope a knowledge-based agent system for intelligent information processing in military domain. We recommend that the students who have interests on this area, take several courses such as 'Artificial Intelligence', 'Information Retrieval', 'Computer Vision', 'Theory of Computation‘, and ’Formal logic‘.
