Abstract
For the analysis of complex group structure, it is necessary to have of a method which can simplify the total structure, and extract the essential macroscopic characteristics. To that end, the CONDENSATION method, a method developed from a concept used in graph theory, is proposed. In this method, sub-groups composed of expanded mutual choice relationships were defind as“components”. A simplified macroscopic structure is described by a graph which is composed of the relationships between components. Further, a necessity of having specific dimensions which can describe the characteristics of the total structure is pointed out. For this purpose, five dimensions are proposed. They are, UNITY, CENTRALITY, POLARITY, HIERARCHY, and the DENSITY.
