Predicting Twitter-Based Information Cascades

The next session at Web Science 2016 starts with a paper by Jure Leskovec on information cascades. Such cascades emerge as users of social media platforms (re)share content through their networks, and the prediction of such processes is traditionally very difficult.

Current Practices in Social Media Data Sharing between Researchers

The next WebSci 2016 presenters are Katharina Kinder-Kurlanda and Katrin Weller, who argue that it is necessary to address the digital divides in data accessibility in social media research. They interviewed a large number of social media researchers, and what emerges from this work is that much data sharing is already taking place, but under varying circumstances.

Identifying MOOC Learners on Social Media Platforms

We start the first paper session at WebSci 2016 with a paper by Guanliang Chen that examines learner engagement with Massively Open Online Courses (MOOCs). These generate a great deal of data about learner engagement during the MOOC itself, but there's very little information about learners before and after this experience. Can we use external social Web data to identify and profile these learners, in order to better customise the learning experience for them?

Web Science and Biases in Big Data

It's a cool morning in Germany, and I'm in Hannover for the opening of the 2016 Web Science conference, where later today my colleague Katrin Weller and I will present our paper calling for more efforts to preserve social media content as a first draft of the present. But we start with an opening keynote by Yahoo!'s Ricardo Baeza-Yates, on Data and Algorithmic Bias in the Web.

Ricardo begins by pointing out that all data have a built-in bias; additional bias is added in the data processing and interpretation. For instance, some researchers working with Twitter data then extrapolate across entire populations, although Twitter's demographics are not representative for the wider public. There are even biases in the process of measuring for bias.

Four New Chapters on the Challenges of Doing Twitter Research

One more post before I head home from the AoIR 2015 conference in Phoenix: during the conference, I also received my author’s copy of Hashtag Publics, an excellent new collection edited by Nathan Rambukkana. In this collection, Jean Burgess and I published an updated version of our paper from the ECPR conference in Reykjavík, which conceptualises (some) hashtag communities as ad hoc publics – and Theresa Sauter and I also have a chapter in the book that explores the #auspol hashtag for Australian politics.
