Striking, marching, tweeting: Studying how online networks change together with movements

This article aims to achieve a better understanding of how online networks contribute to the organization and the symbolic production of social movements using big data coming from social media platforms. It traces and compares online social and semantic networks that emerged on Twitter during two protest events organized by the feminist Italian movement Non Una Di Meno (NUDM) - a national strike organized on March 8th, 2017 and a march organized on November 25th of the same year. Our results suggests that, over time, online networks created on Twitter remain sparse and centralized around the movement handle but that they continue to host an interactive dialogue between the movement, its activists, and supporters. Also, over time, participants to online conversations around NUDM tend to use Twitter to discuss different aspects of the mobilization - paying more attention to the spaces of the protest during the strike and to the issue of gender-based violence in November
