Task 1 Imagine a knowledge base system for finding a fault in a car. A dialogue between the computer and the user might proceed as follows: Computer: Does the engine turn when you engage the ignition? User: No. Computer: When you put the lights on do they go dim? User: Yes Computer: When you turn the ignition is there a clicking sound? User: Yes. Computer: The starter motor in your car has jammed 1.1. What are the knowledge base components (Data, rules and structures) related to the above motor car faulty diagnosis system (LO1.1 Part i)? 1.2. Describe how such computer systems perform inferencing. How to use Forward & Backward chaining inferencing mechanisms for the knowledge management. Describe related to the above motor car faulty diagnosis system. (L0 1.1 Part ii) 1.3. Do you agree that computers with artificial intelligence technologies (Expert systems in fault

Task 2

Consider the decision-making situation defined by the following rules:         

If I go to college and attend lectures, then I will learn something. If I go to college and not attend lectures, then I will miss the lessons. If I attend lectures and study hard then I will pass the exams. If I learn something then I will be knowledgeable. If I miss the lesson then I can’t complete my assignments. If I pass the exams, then I will graduate. If I am an IT Professional and hardworking, then I will earn more money. If I earn more money, then I will go on a trip. If I graduate or go on a trip, then I will be happy.

2.1. Follow the rules for the following situations (what do you conclude for each one?):    

If I go to college and attend lectures. If I go to college and not attend lectures. If I attend lectures and Study hard. If I am an IT professional and hard working.

Are there any other combinations that are valid? Explain. What needs to happen for you to “be graduate” in this knowledge universe? Start with the conclusion “be graduate” and identify the rules used (backward) to ge t to the needed facts.

(LO.2.1)

Write a prolog program or other third-generation language program and knowledge base to execute this knowledge. (LO.3.1)

3.2. Validate the user inputs and provide error m essages for invalid inputs. (LO 3.2, M 1.2)

3.3. Identify and implement opportunities for e rror handlings. (LO.3.3)

3.4. Test the above system using well designed test cases and provide all the test documents (LO 3.4) Hint: -Using your program answer the following questions 

Can jets fly?



Do jets have wheels?



What is the zero-emission car?



Can sail boats fly?



Are sail boats need fuel?

3.5. Prepare a user document to illustrate how to work with your implemented system. (LO.3.5)
