The National Laboratory for Social Innovation is again supporting our research centre’s NLP-based research into e-menatl health forums

2023.10.10. Discursive framing of depression in online health communities

Good news:

The National Laboratory for Social Innovation is again supporting our research centre’s NLP-based research into e-menatl health forums. The research team is led by Domonkos Sik, and consists of Jakab Buda, Renáta Németh, Márton Rakovics, and our guest researchers: Máté Kapitány-Fövény Máté (clinical psychologist), Tibor Pólya (narrative psychologist), Bendegúz Zaboretzky (BI analyst). Our one-year research aims to extend the sociologist-data scientist collaboration to the clinical perspective. To our knowledge, there has been no attempt to validate the clinical perspective in the study of forum dynamics, which could be an important step in mapping the impact of e-mental health platforms.

Successful research grant application to the CELSA Research Fund


We have successfully applied for the CELSA Research Fund with the title “Representations of Migration in a Transforming Europe: The Polarizing Power of Migration as a Political Tool in Online Media and Political Discourses – What can we learn from the 2015 and 2022 refugee crises?.” CELSA was founded in 2016: ten universities from six countries are currently members of the partnership. CELSA applications always involve researchers from KU Leuven together with researchers from the other universities. The aim of CELSA is not only to carry out the research submitted, but also to prepare and submit a large EU grant application. Our research project is led by Leen d’Haenens from KU Leuven and Ildikó Barna from RC2S2. Renáta Németh, Jakab Buda and Zsófia Rakovics are also involved in the research on behalf of our research center.

Our two-year long project explores the mechanisms through which migration is used as a political tool and becomes a source of political polarization reflected in language use. We will analyze the discourse related to the 2015–2016 refugee crisis and the Ukrainian refugee crises in multiple layers of the political public sphere in Belgium and Hungary. The project adopts an innovative methodological approach that combines computational text analysis, qualitative discursive analysis, network analysis, and quantitative statistical methods. Our aim is to map the representation of migration in the Hungarian and Belgian online political and media sphere and identify forms of language polarization against a backdrop of transformation.

According to the reviews, “proposed research topic is very relevant today” and „the project addresses very important and relatively novel topic, which is of high relevance not only for academia but also for EU policymaking.” We also consider the winning application to be a particular success because 65 of the 77 research projects funded in the last six cycles were in the natural sciences. Of the projects funded by CELSA so far, only three have included a social science component, but no research exclusively in the social sciences, such as ours, has ever been funded.

EuMePo Jean Monnet Network’s International Conference organized by ELTE RC2S2 Achieves Great Success

2023.06.16. EuMePo Jean Monnet Network on memory politics

The EuMePo Jean Monnet Network, organized by ELTE RC2S2, held its international closing conference in Budapest, Hungary, between 14-16 June 2023. The EuMePo Conference brought together researchers to explore various aspects of memory politics and remembrance especially in Europe but putting it into an international context. A special feature of the conference was the participation of eighteen students from the Study Tour in European Memory Politics. The conference program encompassed a wide range of presentations and discussions, providing a comprehensive platform for knowledge exchange and critical analysis.

Panel I, funded by the Konrad Adenauer Foundation Canada, examined memory politics in a regional perspective, specifically focusing on the potential emergence of a new East-West divide. Panel II, which delved into the theme of commemorating the past across Europe and explored remembrance and memorialization in education. The first day concluded with an IWalk tour led by the Zachor Foundation for Social Remembrance and followed by a Youth Panel funded by the Konrad Adenauer Foundation Canada where students and established scholars were engaged in follow-up activities. On the second day, the conference continued with a “sightseeing tour” in the world of automated text analytics presented by the ELTE Research Center for Computational Social Science. Panel IV examined the concept of intergenerational trauma after violence, focusing on memory, narrative, and agency among vulnerable populations. In the afternoon, participants visited the House of Terror to gain a deeper understanding of the local context of memory politics. The day concluded with Panel V, which continued the exploration of intergenerational trauma after violence, emphasizing remembrance, reconciliation, and resilience. The final day of the conference, began with Panel VI, which examined the dynamics of remembrance and amnesia, and the silences within memorialization processes. Panel VII shifted the focus to museums and memorialization, exploring how collective memory is manifested in these spaces. The conference concluded with a field exploration of Hungarian memory politics with a guided tour to the Monument of National Martyrs, Memorial of National Unity, and Liberty Square. Overall, the EuMePo Conference served as a vital platform for interdisciplinary discussions and critical analysis of memory politics, remembrance, and memorialization in Europe.

Capturing social relations through computational analysis of textual data


Our research group is organizing a workshop on 20 September. Over the past four years, we have been supported by several national and international grants, and the workshop aims to present our current research results.

Our workshop also aims to present some of the linguistically grounded social research in other fields by inviting a representative from Hungary. We hope that these presentations will provide inspiration for broadening the tools coming from the informatics field, promoting interdisciplinarity and capturing valid content results.



The work of our PhD researcher, Árpád Knap, was selected among the best of the New National Excellence Programme (ÚNKP) 2020/21 cycle at ELTE, based on his final report and presentation. In his research entitled “Analysing emotions related to twentieth-century traumas using text analytics methods” Árpád analysed newspaper articles related to two major events of the twentieth century, the Treaty of Trianon and the Holocaust, using natural language processing methods. A summary video of his research can be viewed here. Based on the research, two academic publications were published – one in English, co-authored with Ildikó Barna and one in Hungarian with Diána Bartha and Ildikó Barna. The publications are expected to be published soon, and will be announced on our website.

Our first Digital Lens kick-off meeting


We’ll be working with the database of testimonies from Hungarian Holocaust survivors from the immediate postwar period. Incredibly some typed protocols have only been recently discovered… With our research we will strive to find more of these hidden treasures. Meanwhile we’ll be analyzing the available material with automated quantitative and qualitative text analytics methods.

We’ve won a Research Grant – Digital Lens


With Ildikó Barna as project leader, our project “Revisiting Early Testimonies of Hungarian Jewish Holocaust Survivors through a Digital Lens” has been awarded a research grant for the next three years. In our interdisciplinary project, we will analyze the digitized database of Hungarian Jewish Holocaust survivors’ immediate post-war testimonies conducted by the National Committee for Attending Deportees (DEGOB) using Natural Language Processing.

Ildikó Barna and Árpád Knap at the 2021 ISCA conference

2020.12.30. Online Antisemitism

Good news. Ildikó Barna and Árpád Knap are among the speakers of the 2021 ISCA conference organized by Indiana University. The “Antisemitism in Today’s America: Manifestations, Causes, and Consequences” conference is one of the most important international forums for antisemitism researchers. Ildikó and Árpád present a comparative analysis of Hungarian and American conspiracy theories related to György Soros, using NLP analysis of online discourses. It is a special pleasure for us to say, that according to the head of the organizing institute, “Your paper promises to make a particularly interesting contribution to our collective work on contemporary antisemitism.”



Three members of our research group (Renáta Németh, Eszter Rita Katona, Zoltán Kmetty) recently published an article, which aims to present the characteristics and possibilities of automated text analysis. Their goal is to inspire Hungarian social scientists by providing an insight into a less-institutionalized area, since they believe that at an international level, text mining will be a standard method for empirical social science research within a few years.

RC2S2 presentations at the conference “Sociology at the Dawn of a Successful Century”

Research summary

Our research focuses on revealing language change in the political public sphere applying NLP (Natural Language Processing) methods on a large digital text corpus in critical discourse analysis framework, which treats language as a tool of ideology and power.

The two highlighted stakes–important for both society and sociology–of the research: (1) The inner workings of the political public sphere on its different levels, the dynamics and interaction between these levels, the exercise of power through language, the expressed ideological polarization, and identification of discourses free of these tendencies. (2) The organic integration of NLP methods into empirical sociology.

Both aspects of the research have international relevance since the studied phenomena of language polarization and diffusion of usage patterns are not specific to Hungary. The integration of NLP methods into empirical sociology is an emerging topic of huge interest because it allows for the new kind of analysis of the large digital corpora at hand utilizing sociological knowledge in the process.

All innovative methodological solutions of data collection and analysis will be made publicly available through digital repositories, scientific articles and conference talks to support the international and domestic users of NLP. Senior members of the research group will provide opportunities to join the project by supervising researches of Scientific Students’ Associations (TDK), master theses and Ph.D. topics for young researchers, and research internships or thesis supervision for graduate students.

Significance of the research

The digital revolution is also the revolution of self-expression. Before the internet, textual documents mainly bore the narratives of the elite, but now almost everybody has the opportunity to express themselves online. The primary relevance of our research is that by the automated processing of this continuously forming flow of texts, even those characteristics of the political public sphere can be examined and understood that have previously been only available in local fragments by the observer. Thus both the social and the scientific stakes of our research are high.

From a scientific standpoint, our research opens new perspectives by involving observational data into quantitative research in addition to previously used self-reported survey data, and also by combining qualitative discourse analysis with quantitative methods, employing new and innovative solutions from computational linguistics. This methodological blend is an international novelty. Using NLP on a large-scale text corpus covering different levels of digital communication–to our knowledge–has never been done in Hungary. While there is evidence for strong ideological polarization (e.g. Vegetti 2018), and polarization in the network structure of the political public sphere has been examined (Bene and Szabó 2019), language polarization has not been researched domestically, and there are only a few examples internationally, which are on a much smaller scale of application compared to our own research (see e.g. Demszky et al., 2019, on Twitter data).

Our research has an important stake from a social standpoint as well: the public sphere is one of the cornerstones of modern democracy and serves an important role in preventing potential distortions and crises.

One of the strengths of the proposal is that it is backed by a young but highly successful research group, already with several international publications, doctoral research topics, and a consciously built domestic and international network of collaborations. Besides the compilation and utilization of innovative methods for sociology, the aim of the research group is to foster the institutionalization of the new and promising automated text analysis methods in social sciences.



A new paper entitled Sociologists using machine learning: Hermeneutic limitations of ‘big data’ text analytics if non-trivial concepts are taught has been published in the International Journal of Qualitative Methods (Q1, impact factor 3.6) by Renáta Németh, Domonkos Sik and Fanni Máté. We were pleased to read the reviews, e.g. “The article is the one of the fundamental researches in this area” and “I look forward to seeing future efforts as you proceed with this research“. We hope that we will be able to fulfil the latter, since we already have three international publications being reviewed.

Our research group working on online antisemitism started a new project on coronavirus-related online antisemitism


Jews have been accused many times throughout the history of deliberately spreading disease among non-Jews. Simultaneously with the outbreak of the coronavirus epidemic, conspiracy theories linking Jews to the virus appeared. The internet is of paramount importance in the distribution of these conspiracy theories. In our research, we examine a large text corpus of Hungarian online articles and comments/posts to answer the research question of whether coronavirus-related antisemitic discourses appear in the Hungarian online space, and if so, what their content is. Our corpus contains articles, comments, and posts written in Hungarian between December 1, 2019, and July 10, 2020, in which the different forms of the word Jew, Zionism, Israel, and that of coronavirus appear simultaneously. Fifteen students from Sociology BA at ELTE University, Faculty of Social Sciences, are participating in the research as interns.



We are pleased to announce that two theses supervised by members of our research group have been awarded the title of “Thesis of the Year”. Anna Farkas wrote the best dissertation at Sociology BA (supervisor: Renáta Németh), and Jakab Buda at Survey Statistics and Data Analysis MSc (supervisor: Márton Rakovics). Congratulations! The dissertations can be found here, along with other dissertations in Computational Social Science led by members of our research team.
