[edit] Knowledge representation
In a model-based reasoning system knowledge is repesented using causal rules. For example, in a medical diagnosis system the knowledge base may contain the following rule:
- patients : Stroke(patient) Confused(patient) Unequal(Pupils(patient))
In contrast in a diagnostic reasoning system knowledge would be represented through diagnostic rules such as:
- patients : Confused(patient) Stroke(patient)
- patients : Unequal(Pupils(patient)) Stroke(patient)
