11. Knowledge-based systems are systems which are not based on the methods and techniques
of Artificial Intelligence.

12. The development of a KBS may require a team of several people working together.
13. Testing is the process in which the knowledge-base systems are checked.
14. End User are the person who designs, classifies, organizes, builds a representation of the

15. Domain Experts provide the information for the Knowledge-base.

2.4 Summary

Knowledge is a progression that starts with data which is of limited utility.
Data and information deal with the past; they are based on the gathering of facts and
adding context.

Knowledge encompasses the implicit and explicit restrictions placed upon objects (entities),
operations, and relationships along with general and specific heuristics and inference
procedures involved in the situation being modelled.

A knowledge-base is a database used for knowledge sharing and management.
The Knowledge-based System division carries out research and development in selected
sub fields of Artificial Intelligence.

Knowledge-based System is a computer program designed to act as an expert in specific
field of knowledge.

2.5 Keywords

Acquaintance: Acquaintance knowledge by acquaintance is obtained through a direct causal
(experience-based) interaction between a person and the object that person perceives.
Heuristic Methods: Heuristic method refers to experience-based techniques for problem-solving,
learning, and discovery.
Inferential Knowledge: Inferential knowledge is based on reasoning from facts or from other
inferential knowledge such as a theory. Such knowledge may or may not be verifiable by
observation or testing.
LISP: LISP is a family of computer programming languages with a long history and a distinctive,
fully parenthesized Polish prefix notation.
Procedural Knowledge: Also known as imperative knowledge, it is the knowledge exercised in
the performance of some task.

PROLOG: PROLOG is a general purpose logic programming language associated with artificial
intelligence and computational linguistics.
