Debates about broadband adoption have gained a new urgency in the United States alongside concerns about the flagging economy and decreased global rankings in high-speed connectivity. Broadband adoption—the process of connecting approximately 100 million U.S. residents who are not online (FCC, 2012a; Horrigan & FCC, 2010)—has become a cause of anxiety and a call to action among policy makers in...

The chapter considers cyberbullying in relation to Internet safety, concentrating on recent, high quality empirical studies. The review discusses conventional debates over how to define cyberbullying, arguing to limit the term to repeated, electronically-mediated incidents involving intention to harm and a power imbalance between bully and victim. It also takes note of the critical perspective ...

Web measurement techniques have been highly influential in online privacy debates and have brought transparency to the online tracking ecosystem. Due to its complexity, however, web privacy measurement remains a specialized research field. Our aim in this work is transform it into a widely available tool. First, we analyze over 30 web privacy measurement studies, identify several methodological...

We investigate the characteristics of factual and emotional argumentation styles observed in online debates. Using an annotated set of FACTUAL and FEELING debate forum posts, we extract patterns that are highly correlated with factual and emotional arguments, and then apply a bootstrapping methodology to find new patterns in a larger pool of unannotated forum posts. This process automatically p...

Massive Open Online Courses (MOOCs) offer a great opportunity for learners to enjoy learning despite their location or timing. Nevertheless, motives vary between each student and another. In this workshop paper, we are delighted to open discussions on why undergraduates may enroll in their university’s MOOCs? Are they looking for ECTS points? Or do they want to build a stronger background in th...

Generations, and generational categories, offer a means of organising our understandings of age and age-related issues. Particularly within practitioner-orientated debates, differences between generations are highlighted as creating tensions which organisations must address. In contrast, we offer a critical interrogation of generations and unpack the implications of particular constructions. Sp...

This work suggests a fine-grained mining of different types of contentious documents, towards a summarization of contention issues. We propose a Joint Topic Viewpoint model (JTV) for the unsupervised identification and the clustering of arguing expressions according to the latent topics they discuss and the implicit viewpoints they voice. A set of experiments is conducted on three type of conte...

We introduce SPRITE, a family of topic models that incorporates structure into model priors as a function of underlying components. The structured priors can be constrained to model topic hierarchies, factorizations, correlations, and supervision, allowing SPRITE to be tailored to particular settings. We demonstrate this flexibility by constructing a SPRITE-based model to jointly infer topic hi...

Online social platforms, e-commerce sites and technical fora support the unfolding of informal exchanges, e.g. debates or discussions, that may be topic-driven or serendipitous. We outline a methodology for analysing these exchanges in computational argumentation terms, thus allowing a formal assessment of the dialectical validity of the positions debated in or emerging from the exchanges. Our ...
