Please answer the questions accurately providing examples where necessary

1. Compare numeric and symbolic processing techniques.

2. Do you agree that using speech communication as the user interface could increase willingness to use expert systems? Why or why not?

3. It is said that powerful computers, inference capabilities, and problem-solving heuristics are necessary but not sufficient for solving real problems. Why?

4. Explain how the Web improves the benefit/cost ratio of ES and enables systems that otherwise are not justifiable.

5. What kind of mistakes might ES make and why? Why is it easier to correct mistakes in ES than in conventional programs?

6. A ready-made ES is selling for $5,000. Developing one will cost you $50,000. A ready-made suit will cost you $100, and a tailored one will cost you $500. Develop an analogy between the two situations and describe the markets for the ready-made and customized products. Why does a ready-made ES costs only 1 percent of the cost of developing one, while a ready-made suit costs 20 percent of the cost of a tailored one?

7. Given the current status of the Web, discuss how it is changing the availability of ES and how it is being used to embed expertise in other systems.
