Maulana, Ardian and Situngkir, Hokky (2020): Divided Information Space: Media Polarization on Twitter during 2019 Indonesian Election.

Abstract

Nowadays, the understanding of the impact of social media and online news media on the emergence of extreme polarization in political discourse is one of the most pressing challenges for both science and society. In this study, we investigate the phenomenon of political polarization in the indonesian news media network based on the pattern of news consumption patterns of Twitter users during 2019 Indonesian elections. By modeling news consumption patterns as a bipartite network of news outletsTwitter user, and then projecting to a network of news outlets, we observed the emergence of a number of media communites based on audience similarity. By measuring the political alignments of each news outlet, we shows the politically fragmented Indonesian news media landscape, where each media community becomes an political echo chamber for its audience. Our finding highlight the important role of mainstream media as a bridge of information between political echo chamber in social media environment
