Managing an Expert System among Others

Expert systems exist for several decades now and have been provided with many tools, for almost any step of their development. However, if all these methods allow for an effective building of such systems, because knowledge itself is still to be acquired, they cannot act on it. Only experts of the domain are thus able to go beyond the process of designing an expert system and to actually evaluating it using other expert systems. We present here a possibility, using the ontology alignment technologies, to confront several expert systems based on heavy ontologies. Given the problem raised by using more than an order of logics at once, we propose a humandriven approach and we describe our model for an environment dedicated to the confrontation of experts systems.
