3. Find out about two applications of AI (not classes of applications, but specific programs). For each application, write, at most, one typed page describing it. You should try to cover the following questions.

(a) What does the application actually do (e.g., control a spacecraft, diagnose a photocopier, provide intelligent help for computer users)?

(b) What AI technologies does it use (e.g., model-based diagnosis, belief networks, semantic networks, heuristic search, constraint satisfaction)?

(c) How well does it perform? (According to the authors or to an independent review?

How does it compare to humans? How do the authors know how well it works?)

(d) Is it an experimental system or a fielded system? (How many users does it have?

What expertise do these users require?)

(e) Why is it intelligent? What aspects of it makes it an intelligent system?

(f) [optional] What programming language and environment was it written in? What sort of user interface does it have?

(g) References: Where did you get the information about the application? To what books, articles, or web pages should others who want to know about the application refer?
