  Knowledge representation (KR) and inference mechanism are most desirable
thing to make the system intelligent. System is known to an intelligent if its
intelligence is equivalent to the intelligence of human being for a particular
domain or general. Because of incomplete ambiguous and uncertain information
the task of making intelligent system is very difficult. The objective of this
paper is to present the hybrid KR technique for making the system effective &
Optimistic. The requirement for (effective & optimistic) is because the system
must be able to reply the answer with a confidence of some factor. This paper
also presents the comparison between various hybrid KR techniques with the
proposed one.
