Abstract：
Many computer systems need to deal with the temporal aspects of knowledge. In fact, various areas in the domain of information systems require temporal representation and reasoning, including Knowledge Management, Decision Support, Intelligent Systems, Database Management, Prediction/Planning, Historical Reconstruction, Diagnosis and Explanation, etc. The purpose of this talk is to: (a) motivate and explain a topic of emerging importance in information systems; (b) provide an overview on some fundamental issues with respects to temporal ontology; (c) present a brief introduction to temporal representation and reasoning in information systems in terms of case tool, Visual Time, together with some illustrating examples.
