Fundamentals of a Turing Test Approach to Validation of Ai Systems

This paper deals with the very fundamentals of a so-called \Turing Test Methodology" for expert system validation which was recently proposed by KGP97]. First, we survey several concepts of veri-cation and validation. Our favoured concepts are lucidly characterized by the words that veriication guarantees to build the system right whereas validation deals with building the right system. Next, we critically inspect the thought-experiment called the Turing test. It turns out that, although this approach may not be suucient to reveal a system's intelligence, it provides a suitable methodological background to certify a system's validity. The principles of our validation approach are surveyed .
