On 15 September 2023, Márton Rakovics, a member of our Research Centre (ELTE RC2S2), gave a lecture in English on the social science applications of natural language processing at the Faculty of Law, Josip Juraj Strossmayer University of Osijek, in Croatia. In his presentation, he introduced the most important text analytical methods used in computational social science and showed some of the results from RC2S2’s research project titled The layers of political public sphere in Hungary (2001–2020) funded by NKFIH (K-134428).

Two members of our research center took part in the 9. International Conference on Computational Social Science (IC2S2) in Denmark. The event is organized by the University of Copenhagen in the Maersk Tower between 17-20^th of July. Below we share some photos of the conference venue and atmosphere.

Zsófia Rakovics and Márton Rakovics presented a poster on language- and political polarization of parliamentary speeches between 1998 and 2020. The examined corpus is related to the research of RC2S2, that is part of an NRCS-funded project The layers of political public sphere in Hungary (2001-2020).

Ildikó Barna gave a presentation titled “An analysis on the framing of Trianon and the Holocaust in Hungary using Natural Language Processing” at the EuMePo (European Memory Politics) Jean Monnet Network conference  on 15th June, 2023, Budapest, co-authored by Árpád Knap. In their research, they examined the discursive framing of Trianon and the Holocaust in today’s Hungarian online media. Their corpus contained 26,519 articles connected to these two historical events published between September 2017 and September 2020. They used a mixed-method approach by combining LDA (Latent Dirichlet Allocation) topic models and qualitative methods. Their aim was not only to map the latent thematic structure and the discourses about Trianon and the Holocaust but also to identify the main differences in the rhetoric of the different sides of the political spectrum. They identified many discursive differences between the rhetoric of the different political sides. Yet, the different relationship to emotions has the most far-reaching consequences. In the far-right and progovernment media, emotions play an essential role, while the rhetoric featured in the nongovernment media, detaches itself from emotions.

Ildikó Barna’s work was supported by the K-134428 NKFIH grant, and Árpád Knap’s work was supported by the EuMePo Jean Monnet Network (Erasmus+ Programme of the European Union) and NKFIH New National Excellence Program.

Renáta Németh gave a presentation titled “Who knows it better? The task of detecting discrimination using human coding vs. text mining” at the EuMePo (European Memory Politics) Jean Monnet Network conference  on 15th June, 2023, Budapest. The co-authors were Jakab Buda and Bori Simonovits. In their study they assess the responsiveness of Hungarian local governments to requests for information by Roma and non-Roma clients, relying on a nationwide email study that applied a randomized controlled trial design. Two methods were used in parallel to evaluate the response emails in parallel: traditional qualitative coding and machine learning (ML). Both methods provided evidence of attention discrimination. Our ML models worked significantly better compared to random classification, confirming the differential treatment of Roma clients. The most important predictors showed that the answers sent to ostensibly Roma clients are not only shorter, but their tone is less polite and more reserved, supporting the idea of attention discrimination. A higher level of attention discrimination is detectable against male senders, and in smaller settlements.

The study showed that it is possible to detect discrimination in textual data in an automated way without human coding, and that ML may detect linguistic features of discrimination that human coders may not recognize. To the best of the authors’ knowledge, the study is the first attempt to assess discrimination using ML techniques.

Renáta Németh’s and Jakab Buda’s work was supported by the K-134428 NKFIH grant, and Bori Simonovits’s work was supported by the FK-12798 NKFIH grant.

Zsófia Rakovics gave a presentation titled “Memory politics – Different issues and political communication strategies in the Hungarian Parliament” at the EuMePo (European Memory Politics) Jean Monnet Network conference  on 15th June, 2023, Budapest. The motivation of the research is to analyze the themes of memory politics and the dynamics of their occurrence in the Hungarian National Assembly and reveal the communication strategies of political parties. The corpus under study contains parliamentary speeches from 1998 to 2020, hundreds of thousands of texts. In addition to the transcripts, metadata is also available; including the date, type, length of the speeches, the name and party of the speakers, which are used for the analysis. The research is conducted by using natural language processing tools, relying on automated quantitative analysis of large amounts of textual data. The study takes an exploratory approach, uses structural topic models (STMs) to investigate the emergence and dynamics of different memory politics related themes. This method simultaneously identifies thematic text clusters, and communication patterns, while capturing semantic and syntactic features. The modeling is performed in two steps: first, for the whole corpus, and second, for the speeches that most typically belong to the topic of memory politics. In both models, time is handled as an explanatory variable in the analysis, considering temporal variation and dynamics. In the data-driven analysis, the memory policy strategies of parliamentary parties, and their changes over time can be investigated on the speeches.

The results point to the political communication turnaround in 2010, highlighting the difference between the language before and after 2010. This year marks a turning point for almost all parties, both in terms of general discourse and in terms of the political themes of memory. The results also confirm the preliminary assumptions for each parliamentary party, illustrating the differences in their memory politics and communication mechanisms.
