First published in 1985, this book provides the psychiatrist with a basic knowledge of the methods and concepts used in the sphere of artificial intelligence. The techniques not only involve building models of the mind (and hence aid hypothesis testing) but also incorporate programs to assist the everyday work of psychiatrists. Knowledge representation, natural language understanding, search and planning, computer-assisted diagnosis, simulation and teaching are discussed. Enough basic theory is outlined to enable readers to understand and to carry out research in the area and to take part in the major ethical debate which will affect the direction of research in the area.
