Principles of Information Science

Chapter 10 Methodology, Applications & Progress

§1 Introduction
Background for New Methodology
Modern natural science me

thodology is mainly based on matter and energy. Even though matter and energy are still necessitate factors in information system, yet the characteristic feature of information systems, particularly the complex ones, is neither matter nor energy, but information. Without information, the complex information systems, like brain and intelligent life, cannot be understood.

The Weakness of Old Methodology
Structuralism (Matter) – The Same Function May Have Different Structure Functionalism (Energy) – The Same Function May Have Different Mechanisms Information – Central Mechanism for Complex Systems

§2 Methodology of Informatics
The main body of the methodology includes: -- Information (Mechanism) analysis of complex systems -- Information (Mechanism) synthesis of complex systems -- Information (Mechanism) evolution of complex systems The related criteria of the methodology include: -- The trinity of matter, energy, and information; -- The trinity of structure, function, and behavior.

Mechanism for Intelligent System

Information

Knowledge

Intelligence

§3 Implications of The Methodology
It is complementary to the traditional methodology . The applicability of the methodology is mainly in the complex systems, like intelligence, biological function and behavior understanding and simulation. Human society, as well as many macro-systems in economy, is also a complex system with information as a dominant, and characterized, factor. As result, the methodology should be applicable to social science and economic systems.

A New Tendency
Ancient Time Shallow-and-Unitarily Thinking Modern Time Divided-and-Analyzed Thinking Present Time Integrated and Comprehensive Thinking Information Science is one of the examples.
