Elevator pitch

The spread of conspiracy theories on social media through protest movements is a societal problem. For effective countermeasures, understanding the movement’s spatial manifestation is essential. This talk explores how leveraging a geo-social network analysis of Twitter data can address the issue.

Abstract

The COVID-19 pandemic and associated policy measures lead to world-wide protest movements that were singled out by the spread of misinformation and conspiracy theories, predominantly on social media platforms. Publicly available social media data therefore is a powerful proxy for studying these protest movements. The data, consisting of user locations, follower relationships, and content information, allows to understand the geographical centers of activity, network structure, and key themes of conspiracy movements.

This talk will present a multi-dimensional network analysis for the Austrian COVID-10 protest movement using Python libraries like geopandas, networkx and gensim. In particular, it will demonstrate how to identify geo-spatial hot spots using spatial statistics, densely connected clusters within the network by employing community detection techniques, as well as dominating content themes through topic modeling approaches.

The presentation highlights how data-driven analysis enables further understanding of movements that may pose threats to democracy, alongside the importance of publicly available social media data for addressing societal challenges.
