Abstract
Production rules are the most common knowledge representation paradigm used in Knowledge Based Systems (KBS). In these notes we will examine the structure of a rule Backward Chainer (BC), a particular rule firing strategy that is the basis for goal-directed search in the Knowledge Base. First, we will describe the recursive nature of a simple BC, without considering uncertainty. Then, we will extend the definition of the BC to a simple representation of uncertainty. Finally we will suggest enhancements for more complex versions of the BC.
