Topics (Disinformation)

Abstract

The topic variable is used in research on disinformation to analyze thematic differences in the content of false news, rumors, conspiracies, etc. Those topics are frequently based on national news agendas, i.e. producers of disinformation address current national or world events (e.g. elections, immigration, etc.) (Humprecht, 2019).

Field of application/theoretical foundation:

Topics are a central yet under-researched aspect of research on online disinformation (Freelon & Wells, 2020). The research interest is to find out which topics are taken up and spread by disinformation producers. The focus of this research is both on specific key topics for which sub-themes are identified (e.g. elections, climate change, Covid-19) and, more generally, on the question of which misleading content is disseminated (mostly on social media). Methodologically, the identification of topics is often a first step followed by further analysis of the content (Ferrara, 2017). Thus, the analysis of topics is linked to the detection of disinformation, which represents a methodological challenge. Topics can be identified inductively or deductively. Inductive analyses often use a data corpus, for example social media data, and try to identify topics using techniques such as topic modeling (e.g. Boberg et al., 2020). Deductive analyses frequently use topic lists to classify contents. Topics lists are initially created based on the literature on the respective topic or with the help of databases, e.g. by fact-checkers.

References/combination with other methods of data collection:

Studies on topics of disinformation use both manual and automated content analysis or combinations of both to investigate the occurrence of different topics in texts (Boberg et al., 2020; Bradshaw, Howard, Kollanyi, & Neudert, 2020). Inductive and deductive approaches have been combined with qualitative text analyses to identify topic categories which are subsequently coded (Humprecht, 2019; Marchal, Kollanyi, Neudert, & Howard, 2019).
