The meaning of links: On the interpretation of hyperlinks in the study of polarization in blogging about climate change

This article explores the potential and challenges of using hyperlinks as data through a study of polarization in English language blogs about climate change. The purpose of this research is to provide an interpretation of the meaning of the hyperlinks in climate change blogs by coding the functions that the links perform in the given blog posts. Beginning with a set of more than 500,000 blog posts about climate change, we focus on bloggers who actively link to highly visible sources that advocate, respectively, the denial or acceptance of the consensus view on anthropogenic climate change. We find that the bloggers in our sample predominantly link to sources that they agree with and that, if they link to a source with different opinions, the link is part of negative criticism of the targeted source. We argue that, by considering the functions of the links in the blog posts, we obtain a more nuanced understanding of the extent to which the discussion in the blogs is polarized.publishedVersio

Polarisation or just differences in opinion: How and why Facebook users disagree about Greta Thunberg

To what extent was Greta Thunberg a ‘polarizing figure’ on Facebook, in the period when she received the most extensive media attention? The paper analyses seven months of discussion concerning Thunberg and her message of intergenerational climate justice, using all relevant posts on public Facebook pages in Germany, Sweden, and the UK. We find that there are many similarities in the attitudes expressed and topics discussed on Facebook in the three countries; however, there are also some striking differences in the levels of polarisation. This comparative study provides evidence that the level of polarisation around these topics on Facebook is very low in Sweden and the UK, but high in Germany. In Germany, a group of political actors stand out as particularly polarising, and, in contrast to the other two countries, the topic of intergeneration justice, the core of Thunberg’s message, is almost absent from the German Facebook discourse. The study shows that Thunberg was not in general a polarising figure in the three European countries and that neither the affordances offered by the platform nor features of her person, message, or activism explain the observed polarisation around Thunberg on Facebook.publishedVersio

Toward ‘Cultures of Engagement’? An exploratory comparison of engagement patterns on Facebook news posts

Information production, dissemination, and consumption are contingent upon cultural and financial dimensions. This study attempts to find cultures of engagement that reflect how audiences engage with news posts made by either commercial or state-owned news outlets on Facebook. To do so, we collected over a million news posts (n = 1,173,159) produced by 482 news outlets in three Scandinavian countries (Denmark, Norway, and Sweden) and analyzed over 69 million interactions across three metrics of engagement (i.e. comments, likes, and shares). More concretely, we investigate whether the patterns of engagement follow distinct patterns across national boundaries and type of outlet ownership. While we are skeptical of metrics of engagement as markers of specific cultures of engagement, our results show that there are clear differences in how readers engage with news posts depending on the country of origin and whether they are fully state-owned or private-owned outlets.publishedVersio

Specifying Policies Using UML Sequence Diagrams - An Evaluation Based on a Case Study

-This report provides a case study based evaluation of UML sequence diagrams as a notation for policy specification. Policy rules are defined on the basis of deontic logic, and provided a trace based semantics interpreted over Kripke structures. This gives a semantic comparable to the UML trace semantics for sequence diagrams, which is utilized in the evaluation. The focus is on requirements with respect to expressivity, utility and human readability. Oppdragsgiver: SINTE

Visualizing Information Diffusion and Polarization with Key Statements

This paper reports ongoing work in the “Networks of Texts and People” project, which is developing methods to visualize the social and epistemological contexts of information contained in blogs. Here, we propose an approach to visualize information diffusion and polarization in the blogosphere, with two novel characteristics. Firstly, we demonstrate how text content can be analyzed and visualized as key statements, rather than as keywords. Secondly, we sketch and discuss ideas for a visual analytic tool that integrates data about blog networks with data about the occurrence of related key statements in blog posts

A dynamic perspective on publics and counterpublics: The role of the blogosphere in pushing the issue of climate change during the 2016 US presidential campaign

Climate change was hardly debated during the 2016 US presidential campaign. Against this background and building upon Fraser's concept of counterpublics (1990), this paper examines whether climate change advocates used the English-speaking blogosphere to push their positions forward. This study uses blog data starting from the Republican nomination of Donald Trump (20 July 2016) to Election Day (8 November 2016) and applies a computerized classification algorithm and topic-modeling techniques to explore, first, the salience of skeptic and advocate positions toward climate change in the English-speaking blogosphere and, second, with which topics these positions are most connected. The results show that the positions and topics of climate change advocates were more salient online than those of climate-change skeptics during the 2016 US presidential campaign. Thus, the study shows that the relation between different publics in societal discourses is not static but may change dynamically over time
