We describe a novel computational dictionary for the study of right-wing populist conspiracy discourse (RPC) on the internet, specifically in the context of contemporary German politics. After first presenting our definition of conspiracy discourse and grounding it in antecedent research on mediated rhetoric at the intersection of right-wing populi...

Computational methods offer a new perspective on the evolving agendas of right-wing movements and parties online. This article showcases computational approaches to text analysis (specifically so-called topic models) to diachronically investigate nativist right-wing issues in social media by comparing comments posted on the Facebook page of the Peg...

E-petitioning platforms are increasingly popular in Western democracies and considered by some lawmakers and scholars to enhance citizen participation in political decision-making. In addition to social media and other channels for informal political communication, online petitioning is regarded as both a useful instrument to afford citizens a more...

Crowd science is scientific research that is conducted with the participation of volunteers who are not professional scientists. Thanks to the Internet and online platforms, project initiators can draw on a potentially large number of volunteers. This crowd can be involved to support data-rich or labour-intensive projects that would otherwise be un...

This paper discusses "citations" and "references" within the microblogging service Twitter with the aim to provide measures for scientific communication on this platform. It provides definitions for different types of citations on Twitter and discusses general difficulties in accessing scientific tweets. Furthermore, two different datasets that rep...

This paper proposes a model for a functional classification of weblogs based on the communicative goals that their users associate with them. I argue that survey data, ethnographic research and linguistic evidence suggests a basic two-way split between weblog entries written to record experiences, for critical reflection and to release emotions (eg...

On the limits of openness in science: between aspiration and reality when sharing research data. Open research data contribute to scientific progress. They allow using old data for new questions and re-analyzing research results. It is hardly surprising that political deci- sion makers, research funders, journals and researchers themselves increasi...
Article

In this paper we compare two academic networking platforms, HASTAC and Hypotheses, to show the distinct ways in which they serve specific communities in the Digital Humanities (DH) in different national and disciplinary contexts. After providing background information on both platforms, we apply co-word analysis and topic modeling to show thematic...
Article
In this article, we discuss the function of quoting and information sharing in social media services and argue that certain aspects of quoting point to similarities with oral culture, where the social functions of sharing complement the aim to inform or disseminate information. We approach the issue by first providing a brief historical account of...

Academic publishing, as a practice and as a business, is undergoing the most significant changes in its 350-year history. Electronic journals and books, both Open Access and behind digital pay walls, are increasingly replacing printed publications. In addition to formal channels of scholarly communication, a wide array of semi-formal and informal c...

In this article, we discuss the ethical issues raised by large-scale online social experiments using the controversy surrounding the so-called Facebook emotional contagion study as our prime example (Kramer, Guillory, & Hancock, 2014). We describe how different parties approach the issues raised by the study and which aspects they highlight, discer...

Metaphors are a common instrument of human cognition, activated when seeking to make sense of novel and abstract phenomena. In this article we assess some of the values and assumptions encoded in the framing of the term big data , drawing on the framework of conceptual metaphor. We first discuss the terms data and big data and the meanings historic...

We characterise different actors in the Twitter data ecosystem: private and institutional end users of Twitter, commercial data resellers such as Gnip and DataSift, data sci...
