The knowledge base for computer-aided diagnosis of mental disorders based on psychometric tests

The knowledge base is a key element of many decision support systems. In the paper, we describe, the knowledge base implemented in the Copernicus system - a tool for computer-aided diagnosis of mental disorders based on data coming from psychometric tests, in the current version, coming from the Minnesota Multiphasic Personality Inventory (MMPI) test. This tool uses a variety of classification ways for differential interprofile diagnosis. Therefore, the knowledge base embodied in the tool is of different character. The special attention is focused on new elements added in the last version of the Copernicus system.
