We always seem to be comparing various conceptual structures in many of our higher mental activities. In any case, we use similarities and discrepancies in forming all our conceptual categories. In this book, the authors present a computerized approach to diagnosis: in particular, cognitive diagnosis. It uses fuzzy graph structures called fuzzy cognitive maps (FCMs). These are used in an attempt to model the intriacies of the higher mental processes. The area of structure comparison, focusing on measures of similarity and discrepancy, is also dealt with. A very interesting aspect of the book is how the authors approached the problem of cognitive diagnosis using fuzzy techniques. Some connections and differences from other approaches are also covered. The reader will find this book both informative and interesting.
