Day 2 of the #MEDemConference at @gesis.org starts with powerful tool demos:
🔍 AmCAT @sof14g1l.bsky.social on enabling large-scale text analysis of media & political debates.
🌐 HarDIS @sziaja.bsky.social on harmonizing and sustaining cross-national democracy data (surveys, parties, experts).
Sofia Gil-Clavel stands at a podium presenting AmCAT at the 3rd MEDem Conference. Behind her, a slide shows the AmCAT team (Kasper Welbers, Wouter van Atteveldt, Johannes Gruber, Sofia Gil-Clavel) with the tagline: “Developed by researchers for researchers, society, and data savvy users.” Logos of MEDem, VU Amsterdam, and the Societal Analytics Lab are displayed at the top. Sebastian Ziaja stands at a podium presenting HarDIS (Harmony in the Democratic Ideological Space) at the 3rd MEDem Conference. A slide behind him shows the HarDIS team (Lea Kaftan, Paul Bederke, Selçuk Timur Uluer) with the logos of MEDem, GESIS Leibniz Institute for the Social Sciences, and OSCARS (the funding initiative).

Authored by @hajoboo.bsky.social, @alexiakatsanidou.bsky.social, S. Kritzinger, G. Lutz, J. Willmann & @jamoeberl.bsky.social – just in time for the upcoming #MEDemConference.
Open science in democracy research: the research infrastructure “Monitoring Electoral Democracy” (MEDem) - European Political Science
Ensuring universal access to scientific research and upholding the principles of keeping data findable, accessible, interoperable, and reusable is of paramount importance to the democratization of science. However, upholding these principles becomes increasingly complex with the increasing scope of data collection, the more different types of data we collect (e.g., survey, text, or institutional and country-level macro data), and the more research teams are involved in data collection. In the domain of democracy research, scientists across Europe are therefore joining forces to launch the research infrastructure monitoring electoral democracy (MEDem), which aims to establish itself as an open platform where the fragmented crowd of researchers in the various research fields can coordinate and develop common standards for data collection both retrospectively as well as prospectively to make their data interoperable, and (comparative) democracy research more productive. Moreover, MEDem will help make democracy research data and findings accessible to the general public (e.g., citizens, journalists, and policymakers).

They say: once there’s a paper 📝, it’s real…
🎉 #MEDem in #EPS @ecpr.bsky.social

The paper outlines how MEDem will strengthen #OpenScience by making data #FAIR in #DemocracyResearch – and how scholars across Europe are joining forces to build a truly open #ResearchInfrastructure ⚙️
Screenshot of the article “Open science in democracy research: the research infrastructure ‘Monitoring Electoral Democracy’ (MEDem)” published in European Political Science. The header shows the journal name, DOI link, and the label “DEBATE.” Below, the title is followed by the author list: Hajo Boomgaarden, Alexia Katsanidou, Sylvia Kritzinger, Georg Lutz, Johanna Willmann, and Jakob-Moritz Eberl. The abstract explains the aims of MEDem as a European research infrastructure to make democracy research data FAIR (findable, accessible, interoperable, reusable). Keywords listed include open science, FAIR data, ESFRI roadmap, research infrastructure, democracy research, data harmonization, data linking, and data set search.

Thrilled to share that this study, which I started back in 2021, has finally been published! 🎉 While topic modeling may not be the most cutting-edge anymore, the discussion on validation & standardization is still highly relevant. Proud of this work & contribution! 🙌📚
