EVALUATION AND EXPLOITATION OF KNOWLEDGE ROBUSTNESS IN KNOWLEDGE-BASED SYSTEMS

Industrial knowledge is complex, difficult to formalize and very dynamic by reason of the continuous development of techniques and technologies. Verification and validation of knowledge bases at the time of theirs elaborations is not sufficient. To be exploitable, knowledge must then be able to be used under conditions (slightly) different from conditions in which it was formalized. So, it becomes vital for the company to permanently evaluate the quality of the industrial knowledge implemented in the system. This evaluation is founded on the concept of robustness of knowledge formalized by conceptual graphs. The evaluation method is supported by a computerized tool.
