Subject: artificial intelligence
Forward chaining and Backward chaining
Suppose that the coding resulting from the acceptance of knowledge is as follows:
A1 = body temperature >= 38°C
A2 = cough
A3 = cold
A4 = persistent cough especially at night
A5 = breath sounds
P1 = common fever
P2 = normal cough
P3 = influenza / viral infection
P4 = whooping cough
P5 = respiratory tract infection
The rules on the knowledge base include:
R1 : IF A1 THEN P1
R2 : IF A2 THEN P2
R3 : IF P1 and (P2 or A3) THEN P3
R4 : IF P3 and A4 THEN P4
R5 : IF P3 and A5 THEN P5
The facts obtained from the user are that the fever, cough, and cough are more frequent at night (A1, A2, A4 → true). Explain the steps to get a conclusion if the inference technique used is:
a. Forward chaining
b. Backward chaining
