✦ Synopsis

This paper aims at describing a testing method devoted to the study of knowledge-based systems (KBS) behaviour and results. Like any validation method, this method relies on specifications. Moreover, as the focus of the study is KBS behaviour, these specifications need to be expressed at high level. We distinguish between two kinds of specifications, system specifications and anomaly specifications, depending on the validation objectives. We adopt a knowledge-level perspective of validation since our first objective is to compare the KBS behaviour to expected behaviours that are a part of system specifications and described within a KADS conceptual model. In order to detect inconsistent results, we propose to add some kind of validation knowledge to the domain level knowledge. This method is illustrated by the validation of a prototype for natural language understanding.
