Working memory stores an expert system’s input data and tracks facts deduced during reasoning. It connects the knowledge base with the inference engine without containing the domain rules itself. section 2.1
During an inference cycle, working memory:
- Holds initial observations and other input data. section 2.1
- Receives new facts generated when rules match its current contents. section 2.1
- Tracks modified facts while reasoning continues or stops when no rule can trigger. section 2.1
MYCIN
MYCIN used information about bacterial organisms, infection sites, and clinical signs such as fever or headache as inputs for rule-based diagnosis. section 2.1
