Outline



Introduction• Modern knowledge-intensive businesses

• Multi-disciplinary• Decision-making• Implementation • Multi-culture

• Semantic knowledge management



Notions

• Data, information and knowledge• Knowledge in context and dichotomy• Ontology• Knowledge management and its

objectives• Knowledge standardization and

instantiation• Semantic KM



Computer-based KM

• General KM model• Nonaka's knowledge conversion model• Knowledge dichotomy and Nonaka's KM

model transcription• Computer-aided KM• Matters in computer-aided KM

Matters in computer-aided KM

• Partly freeing human from mental work • Enlarging the scope of knowledge reusing and sharing • Reducing knowledge management costs• Unifying knowledge processing
