Analyzing freedom: NLP study explores Swiss narratives
A new study by Giovanni Spitale, Federico Germani, Frank Fritschi, Sonja Merten, and IBME director Nikola Biller-Andorno examines how the moral key term “freedom” was used in Swiss public communication during the COVID-19 pandemic.
The COVID-19 pandemic was not only a public health crisis. It was also a crisis of public discourse. Terms such as , , and became central to political debate, media coverage, and everyday communication. Yet these terms were not always used in the same way across different public arenas.
In the study “Analyzing freedom: Understanding Swiss COVID-19 narratives through NLP analysis,” Giovanni Spitale, Federico Germani, Franc Fritschi, Sonja Merten, and Nikola Biller-Andorno analyzed how the concept of freedom was framed in during the pandemic. The study is part of the Schweizerischer Nationalfonds SNF NRP80 project “Boosting Public Discourse,” which investigates how public debate can be strengthened in times of societal crisis.
Using a natural language processing pipeline, the authors examined three datasets: official press releases from the Swiss Federal Office of Public Health, newspaper articles from major Swiss media outlets retrieved via Factiva, and social media posts collected through CrowdTangle. The analysis combined lemmatization, co-occurrence analysis, and semantic network mapping to identify how “freedom” appeared in different communicative contexts.
The findings show substantial differences across these arenas. Official communication tended to frame freedom in relation to public health responsibilities and personal autonomy. Newspaper coverage emphasized tensions between restrictions and civil liberties. Social media discourse, by contrast, was more polarized, with recurring themes of activism, distrust in authorities, and conflicts between individual and collective understandings of freedom.
The study suggests that different framings of key moral terms may contribute to discursive fragmentation, especially when they interact with pre-existing tensions around institutional trust. At the same time, these framings also reflect broader democratic struggles over how societies should balance individual rights and collective responsibilities during crises.
By mapping how freedom was used across public communication, the study highlights the importance of conceptual clarity in crisis communication. A shared understanding of moral and political key terms can help policymakers, media actors, and public institutions support more informed dialogue, reduce polarization, and strengthen democratic processes.
The paper contributes to the broader goals of NRP80 by showing how computational methods can help identify patterns in public discourse and support more reflective, transparent, and democratic crisis communication.
