Knowledge management: System architectures, main functions, and implementing techniques

Based on existing theoretical models of knowledge management (KM), our investigation on existing KM systems and a prototype system designed for supporting cooperative research in research institutes, we address three important issues in the design and implementation of KM systems, i.e., the software system architecture of a general KM system, the main functions of KM systems and the information processing techniques and algorithms that can be used to implement KM systems.
