Abstract
This paper proposes three new quantification measures of information diffusion characteristics in blogspace. These measures are calculated from the number of three basic structures, which are directed 2-edge connected subgraphs, in information diffusion networks. Each basic structure is related to information scattering, information gathering or information transmission. We analyze and visualize information diffusion networks extracted from six blog datasets. In the result, we show that the difference of information diffusion characteristics can be discriminated by the combination of three measures and human activity in blogspace can be explained by them.
