Getting Ready for Sessions # 12 (October 7, 1998)

Reminder: As next Monday, October 11th is University Day, there will be no class (classes are officially cancelled from 10:00 am until 2:00 pm)

We will begin our consideration of various knowledge representation approaches with rules (If the sky is cloudy, I'd better bring my umbrella). Here conditions and actions are related to enable a knowledge-based system to take some action if some condition is true.

Durkin, J. (1994). Expert Systems: Design and Development. Englewood Cliffs, NJ: Prentice-Hall. [We will be using Durkin during the next several sessions and I have attached all of the Durkin readings together in one package. You ONLY need to read pp. 52-68 for this session. Details for the coming sessions will be provided in future Getting Ready's]

This selection briefly introduces the idea of knowledge and presents the idea of a rule-based knowledge representation.

Given the system that you thought about for Session #11, construct a few rules that would be needed to incorporate knowledge. For example, in an OPAC you might wish to followup any situation of 'no match' between a user's query and the terms employed in the database with the "firing" of such rules as: If 'college' then substitute 'university' in query.
