An expert system is a computer application that performs a task that would be performed by a human expert. For example, since an expert system shell provides a build-in inference engine, the developer can focus on inputting problem-specific knowledge into the knowledge base. Attempts to solve this problem led to the view that the domain knowledge and algorithms for applying this knowledge should be separated explicitly. 3.
