The PartySOME project, launched by Malo Jan and Luis Sattelmayer from Sciences Po's Centre for European Studies and Comparative Politics, allows exploration of political issues addressed by parties on social media and their evolution over time. This interactive tool tracks publications from 478 political parties in 38 Western countries, including the entire European Union, dating back to 2005.
The platform utilizes over 9 million publications collected from 7 social networks (Bluesky, Facebook, Instagram, Telegram, TikTok, Twitter, and YouTube). This data is categorized into 21 standardized political themes, such as immigration, health, and the environment, using computational social science methods.
The website, freely accessible, enables users to track the attention given to various issues or search for specific keywords in party publications, including comparisons between different countries. A dedicated section provides real-time monitoring of the campaign for the 2027 French presidential election and the early general elections in Spain.
The classification methodology is documented in two peer-reviewed academic articles. Aggregated data is available as open access on GitHub, promoting open science. The platform is currently in public beta and regularly integrates new features based on user feedback.
“"The keyword search function of PartySOME makes it possible to compare the use of a word in the publications of parties from different countries."
For instance, searching for the term 'remigration' reveals its emergence about a decade ago in European far-right discourse, initially in Sweden and the Netherlands. More recently, the Citizen Party (BP) in Denmark and Futuro e Popolo (FN) in Italy have used it most frequently.
A query using the keyword 'violence' allows for a comparison, by presidential candidate, of the volume and proportion of publications containing this term. It highlights different framings: 'sexist and sexual violence' for Marine Tondelier, 'police violence' for Jean-Luc Mélenchon, and 'political violence and the far-left' for Marine Le Pen.
