The Computer Psychiatrist

This is the Seed7 version of the famous computer program by Joseph Weizenbaum. Intended to be a parody of a therapist, it was so convincing that some psychiatrists believed, that an automated form of psychotherapy would be possible. The form of a psychiatric interview was chosen to avoid a database of real-world knowledge. The program uses a keyword search and a table of response templates. Using the templates it rephrases many of the patient's statements as questions and poses them to the patient. This simple mechanism works so good that some people did not believe that they talked to a program, even after the facts where shown to them. To exit the program just write shut.
