The contemporary debate about the role of political digital echo chambers (DPECs) relies more on assumptions, guess work, and speculations rather than empirical conclusions. Such shortcomings reflect the lack of empirical tools to measure the communication between echo chambers and the outside world. We try to overcome this deficiency by construing three graph-level metrics, Invasiveness, Intrusiveness and Influence, which try to capture the information dominance of a DPEC over another one, its strength of information source, and the penetration capability of one DPEC’s message deep into another DPEC’s space, respectively. We tested our metrics with simulated and real network data, and they seem to respond according to their design and our expectations. |
