Knowledge acquisition as an empirically based modelling activity
When knowledge engineering is consequently looked upon as scientific discovery, certain prescriptions can be derived about how to observe expertise and how to deal with intermediate stages of the modelling process. These prescriptions concern roles played by underlying assumptions, theories and paradigms of cognitive science and their respective implications upon conduction and interpretation of individual experiments, and the language(s) used in the modelling process. Most essentially, scientific discovery is characterized by planned feedback, including theory based identification of contradicting or falsifying evidence. Some of these characteristics clearly differ from principles suggested in KADS for the respective modelling activities.
