strategy system (forward chaining or backward chaining) is more applicable when making evaluations in expert management, especially in the academic field.

Students should understand the architecture and organization of expert systems and issues involved in designing an expert system. At the end of this lesson the student should be able to do the following: • Represent a knowledge base as a set of rules if possible. • Apply forward/backward chaining algorithm as suitable.

ABSTRACT. The forward and backward chaining techniques are well-known reasoning concepts used in rule-based systems in Artificial Intelligence. The forward chaining is data- driven, and the backward chaining is goal-driven reasoning methods. The aim of this thesis is to present the implementation of above concepts.
