As understood by
Philippe A. MARTIN
- Knowledge acquisition/engineering (KA/KE)
- Goal: Building a knowledge-based system (KBS)
- Method:
- Prototype-based knowledge acquisition/engineering
- Goal: Building a knowledge-based system (KBS)
- Subtask: (Adapted from: Heijst & al., 1996)
- Data collection
- Input: Expertise sources
- Output: Expertise data (e.g.: organisational model,
interview retranscription, technical documents)
- Prototype design (Input: Expertise data; Output: KBS)
- Method:
- Using ripple-down procedures (Paul Compton)
-
- Model-based knowledge acquisition/engineering
- Goal: Building a knowledge-based system (KBS)
- Subtask: (Adapted from: Heijst & al., 1996)
