In this article, we take issue with the claim by Sunstein and others that online discussion takes place in echo chambers, and suggest that the dynamics of online debates could be more aptly described by the logic of 'trench warfare', in which opinions are reinforced through contradiction as well as confirmation. We use a unique online survey and an experimental approach to investigate and test ...

Research on automatic text summarization has primarily focused on summarizing news, web pages, scientific papers, etc. While in some of these text genres, it is intuitively clear what constitutes a good summary, the issue is much less clear cut in social media scenarios like online debates, product reviews, etc., where summaries can be presented in many ways. As yet, there is no analysis about ...

Patients discuss complementary and alternative medicine (CAM) in online health communities. Sometimes, patients' conflicting opinions toward CAM-related issues trigger debates in the community. The objectives of this paper are to identify such debates, identify controversial CAM therapies in a popular online breast cancer community, as well as patients' stances towards them. To scale our analys...

The term metadiscourse rarely appears in translation studies despite the continuously growing body of research on discourse markers in different genres and through various perspectives. Translation as a product that needs to observe such markers for their communicative power and contribution to the overall coherence of a text within a context has not been satisfactorily studied. Motivated by su...

Online debate forums provide a rich collection of differing opinions on various topics. In dual-sided debates, users present their opinions or judge other’s opinions to support their stance. In this paper, we examine the use of users’ intentions and debate structure for stance classification of the debate posts. We propose a domain independent approach to capture users’ intent at sentence level...

Online communities host growing numbers of discussions amongst large groups of participants on all manner of topics. This user-generated content contains millions of statements of opinions and ideas. We propose an abstractive approach to summarize such argumentative discussions, making key content accessible through ‘point’ extraction, where a point is a verb and its syntactic arguments. Our ap...

We describe a pilot study in using argumentation frameworks obtained from an online debate to evaluate positions expressed in the debate. This pilot study aims at exploring the richness of Computational Argumentation methods and techniques for evaluating arguments to reason with the output of Argument Mining. It uses a hand-generated graphical representation of the debate as an intermediate rep...

This article explores how online multiplayer digital games are used as a venue for the negotiation of intellectual property rights. Recent disputes between players and creators are contributing to both a shift in contemporary notions about the nature and limits of copyright and a growing relationship between virtual leisure and real-world economics. A brief overview of the debate as it has been...
