Pick another area of interest for designing an expert system. Answer Exercises 1–3 for this application.

Data from exercise 1

In Section 8.2 we introduced a set of rules for diagnosing automobile problems. Identify possible knowledge engineers, domain experts, and potential end users for such an application. Discuss the expectations, abilities, and needs of each of these groups.

Data from exercise 2

Take Exercise 1 above. Create in English or pseudocode 15 if-then rules (other than those prescribed in Section 8.2) to describe relations within this domain. Create a graph to represent the relationships among these 15 rules.

Data from exercise 3

Consider the graph of Exercise 2. Do you recommend data-driven or goal-driven search? breadth-first or depth-first search? In what ways could heuristics assist the search? Justify your answers to these questions.
