Authority measure for opinion dynamics
Abstract
We propose a formal framework for measuring the authority of individuals in opinion dynamics. Our framework is based on an axiomatic foundation in the tradition of coalitional game theory. We show that the unique solution concept satisfying our axioms is a generalization of the “authority distribution” notion of Hu and Shapley. Our approach is based on the dynamics of opinion exchange rather than on network topology. However, for any fixed opinion dynamics, our authority concept associates a network centrality measure with any given network topology. Earlier as well as new network centrality measures are obtained in this way.
