Quantitative analysis of large amounts of journalistic texts using topic modelling

The huge collections of news content which have become available through digital technologies both enable and warrant scientific inquiry, challenging journalism scholars to analyse unprecedented amounts of texts. We propose Latent Dirichlet Allocation (LDA) topic modelling as a tool to face this challenge. LDA is a cutting edge technique for content analysis, designed to automatically organize large archives of documents based on latent topics, measured as patterns of word (co-)occurrence. We explain how this technique works, how different choices by the researcher affect the results and how the results can be meaningfully interpreted. To demonstrate its usefulness for journalism research, we conducted a case study of the New York Times coverage of nuclear technology from 1945 to the present, partially replicating a study by Gamson and Modigliani. This shows that LDA is a useful tool for analysing trends and patterns in news content in large digital news archives relatively quickly.

Media Reporting of Neuroscience Depends on Timing, Topic and Newspaper Type

The rapid developments in neuroscientific techniques raise high expectations among the general public and therefore warrant close monitoring of the translation to the media and daily-life applications. The need of empirical research into neuroscience communication is emphasized by its susceptibility to evoke misconceptions and polarized beliefs. As the mass media are the main sources of information about (neuro-)science for a majority of the general public, the objective of the current research is to quantify how critically and accurately newspapers report on neuroscience as a function of the timing of publication (within or outside of periods of heightened media attention to neuroscience, termed “news waves”), the topic of the research (e.g. development, health, law) and the newspaper type (quality, popular, free newspapers). The results show that articles published during neuroscience news waves were less neutral and more optimistic, but not different in accuracy. Furthermore, the overall tone and accuracy of articles depended on the topic; for example, articles on development often had an optimistic tone whereas articles on law were often skeptical or balanced, and articles on health care had highest accuracy. Average accuracy was rather low, but articles in quality newspapers were relatively more accurate than in popular and free newspapers. Our results provide specific recommendations for researchers and science communicators, to improve the translation of neuroscience findings through the media: 1) Caution is warranted during periods of heightened attention (news waves), as reporting tends to be more optimistic; 2) Caution is also warranted not to follow topic-related biases in optimism (e.g., development) or skepticism (e.g., law); 3) Researchers should keep in mind that overall accuracy of reporting is low, and especially articles in popular and free newspapers provide a minimal amount of details. This indicates that researchers themselves may need to be more active in preventing misconceptions to arise.

Diverse politics, diverse news coverage? A longitudinal study of diversity in Dutch political news during two decades of election campaigns

Although diverse political news has been recognized as a requirement for a well-functioning democracy, longitudinal research into this topic is sparse. In this article, we analyse the development of diversity in election coverage in the Netherlands between 1994 and 2012. We distinguish between diversity for party and issue coverage, and look at differences between diversity in newspapers and television news. Results show that news diversity varies over time. Diversity for party types increased over time. We found no clear trend for diversity of issue dimensions. Compared to newspapers, television news is more diverse for party types but less diverse on issue dimensions. The question concerning whether these findings are an indicator of structural bias is discussed.

Political News in Online and Print Newspapers: Are online editions better by electoral democratic standards?

The electoral model of democracy holds the ideal of citizens who are well informed about politics, and regards it as a task of news media to provide citizens with political information. Against this ideal, the quality of political news in online news outlets is highly contested. While pessimists point out the dangers of increased competition online, optimists emphasize the potential benefits of unlimited space and interactivity. To see which view holds true, this paper compares political news in popular and elite print newspapers and their respective online editions during the 2013 National Election Campaign in Austria. Findings show that online editions score better than paper editions regarding the amount of political news, (party) diversity, and emotionalization, but differences between newspaper types were notable. Whereas elite newspapers cover politics online more extensively than in print, the reverse is true for popular newspapers. Leader focus is also strong in popular papers online. We conclude that the gap in quality between political news in elite and in popular newspapers is larger online. This might contribute to a wider gap between a well-informed elite audience and a lesser-informed popular news audience, when audiences switch from print to online news.

Media and juvenile delinquency : A study into the relationship between journalists, politics, and public

Between 2007 and 2011, the number of registered juvenile suspects declined by 44 percent, but the Dutch public did not feel any safer. In this research, we study media coverage of youth crime and interview journalists and their sources in order to investigate the relationship between journalists, their sources, and the possible effects on the public with respect to fear of crime. We find an overrepresentation of youth crime in news coverage, especially in the popular press, and a stronger episodic focus over time. All media focus increasingly on powerful sources that focus on repressive framing, but this is especially found in the elite press. We conclude that news coverage in all media groups, although in different ways, does contribute to the fear of crime in society and the idea that repressive measures are needed. The fact that this fear of crime is also caused by news coverage is acknowledged, but neither journalists nor politicians are able or willing to change this.
