Iliad: The Model Used for This Text

In the case of a diagnostic expert system, each disease or diagnostic decision can be represented as a list or table called a frame. The decision frame contains the relevant findings (i.e., disease manifestations), associated logic, and probabilities in the case of a probabilistic (e.g., Baye-sian) frame. Frames can be represented in different ways, e.g., Bayesian, Boolean, and value-type Boolean frames are used in the Iliad expert system.
