Elaborate the importance of Knowledge Base in ES-00385

The knowledge base is the part of an expert system that contains the domain knowledge, i.e.

1. Problem facts, rules
2. Concepts
3. Relationships

As we have emphasized several times, the power of an ES lies to a large extent in its richness of knowledge. Therefore, one of the prime roles of the expert system designer is to act as a knowledge engineer. As a knowledge engineer, the designer must overcome the knowledge acquisition bottleneck and find an effective way to get information from the expert and encode it in the knowledge base, using one of the knowledge representation techniques we discussed in KRR.
