Objectives

After studying this unit, you will be able to:

 Understand the procedural and declarative knowledge
 Illustrate the logic programming
 Compare the forward and backward reasoning
 Understand the matching and control knowledge

Introduction

In this unit, you will understand various concepts of knowledge representation using rules. You
will discuss procedural knowledge and declarative knowledge. Logic programming contain
three major classes of application which are discussed in the unit. You will illustrate the
comparison between Forward and Backward Reasoning. The concept of matching control
knowledge is also discussed.

6.1 Procedural vs Declarative Knowledge

Declarative Knowledge Representation

In Declarative knowledge representation, knowledge is signified as static collection of details
which are influenced by common procedures. Here the details are required to be accumulated
only one and they can be utilized in any number of manners. Details can be easily added to
declarative systems without altering the common procedures.
