A Binary Tree as a Basic Model for Studying Hierarchies using Q-Measures
Yuxian Liu, Raf Gun, Ronald W. Rousseau · SRELS Journal of Information Management · 2013
A binary tree is used as a model for a hierarchical structure. All nodes situated at the same height are assumed to form a group. The global and local Q-value, being measures for the extent to which a node plays a bridging function between groups, are determined. For the global Q-value this is can be done in two ways: a direct one and one via a recursion relation.
