Scale Characteristics of Information Propagation on Blogs Determined by Network Structure

Abstract

We focus on blogs' information propagation, that is part of information propagation on the real world. Our objective is to make it clear how the size of the information propagation is distributed and what determines this distribution. This is because the size distribution make an important role in the information propagation. To do so, we search for a proper mathematical model by comparing a result of information propagation distribution on the blogs observed on a real network with ones derived from a mathematical model. The number of entries propagated by cascaded trackbacks is used as the size of information propagation. A percolation model on a complex network is adopted for the mathematical model. As a result, the information propagation appeared on the blogs is similar to the percolation model on a scale-free network.
