We live in an uncertain world that means uncertainty cannot be avoided in
our real world application. Uncertainty has already influenced many
theories and concepts in modern science as a great utility in solving many
real world problems essentially. Living in uncertain world is also
represented in human communication that usually uses perception-based
information. Therefore, it is necessary to construct a computer-based
information system called "Intelligent Information System" that is able to
process perception-based information. In the future through the
Intelligent Information System, humans are able to communicate with
computers in the level of perception-based information. Here, perception
is defined as a process of translating sensory stimulation into an
organized experience. Perception is an intrinsic aspect in human-based
information. In the perception-based information, the information might be
incomplete, imprecise, fragmentary, vague, contradictory, etc. All
characteristics of information are considered as various types of
uncertainty. They need a hybrid soft computing techniques to construct the
intelligent information system.

As proposed by L. A. Zadeh in 1990, unlike hard (conventional) computing,
soft computing is tolerant of imprecision, uncertainty, partial truth, and
approximation to achieve tractability, robustness and low solution cost.
Soft Computing is a human mind-based computing. The human mind, unlike
present day computers, possesses a remarkable ability to store and process
information which is pervasively imprecise, uncertain and lacking in
category. Some principal constituents of soft computing are Fuzzy Systems,
Probabilistic Reasoning, Granular Computing, Belief Network, Neural
Networks, Evolutionary Computation, Machine Learning, Chaos, DNA
Computing, etc. The principal constituent methodologies in soft computing
are complementary rather than competitive. Soft computing is a partnership
in which each of the partners contributes a distinct methodology for
addressing problems in its domain. Soft computing may be viewed as a
foundation component for the emerging field of conceptual intelligence.
The employment of soft computing techniques leads to systems which have
high MIQ (Machine Intelligence Quotient).

A simple example of hybrid soft computing techniques is given by a
complementary among fuzziness, roughness and probability. It is clear that
probability and fuzziness work in different areas of uncertainty. Here,
fuzzy event in the presence of probability theory provides probability of
fuzzy event in which fuzzy event could be regarded as a generalization of
crisp event. Moreover, in rough set theory, a rough event is proposed
representing two approximate events, namely lower approximate event and
upper approximate event. Similarly, in the presence of probability theory,
rough event can be extended to be probability of rough event.
