ABSTRACT
MEDAS, a Bayesian diagnostic system, includes a Feature Dictionary that contains descriptions of signs, symptoms, and test results, along with alternate medical terminology used in various fields and parts of the country. The Feature Dictionary has now been expanded to include feature interactions to support test selection and treatment protocols. The feature interactions required to provide this flexibility are drug side-effects and allergic reactions, contraindications IO tests and treatment, and drug interactions. Although the primary use of the dictionary is to store the feature information to be used by the MEDAS diagnostic system, adding further functionality allows other applications, both inside and outside of MEDAS to be supported. Generic and brand names of drugs appear as synonyms in the dictionary. This widens our abilities to translate data from one system lo another.
