Abstract

INTERDAT is computer software which substitutes a human interviewer. INTERDAT asks questions and tries to understand the responses by attributing mental models to the interviewee. The correctness of these models is tested by forecasting the responses to new questions. INTERDAT has many possibilities to adapt its models till it reaches the desired degree of understanding. Technologically INTERDAT is an Artificial Intelligence programme which is written entirely in LISP and to our knowledge the first Al application in sociological research.
