The final speaker in this session at AoIR 2016 is my DMRC colleague Brenda Moon. She points out that hashtag studies on Twitter are subject to significant limitations because they capture only those tweets that have been explicitly marked with those hashtags, but may not also examine the broader conversation that might unfold around those hashtagged tweets without being itself hashtagged. There is a need here to move beyond quantitative and computational analysis of these datasets as well – so the challenge here is to identify reply chains and to examine them more qualitatively.

The present study focusses on discussion …

The final session at AoIR 2016 today starts with a presentation from Daniela van Geenen. She begins by noting that much Twitter research has focussed on specific events, incidents, and groups rather than on longer-term, everyday uses. Is it possible instead to identify local publics on Twitter, based for instance on geographic co-location? Are such publics connected with national networks?

A mapping of Twitter users in Utrecht has found some evidence for this. Can this be expanded to the national Twittersphere of the Netherlands, which comprises some 2.6 million accounts (of which 0.9 million are active), or 5.7% of …

Our Digital Methods pre-conference workshop at AoIR 2016, combining presenters from the Digital Methods Initiative at the University of Amsterdam and the Digital Media Research Centre at Queensland University of Technology starts with a presentation by Richard Rogers on the recent history of digital methods. He points out the gradual transition from a conceptualisation of the Internet and the Web as cyberspace or as a virtual space to an understanding of the Web as inherently linked with the 'real' world: online rather than offline becomes the baseline, and there is an increasing sense of online groundedness.

In the process …

I’m on my way to Berlin for this year’s Association of Internet Researchers conference, which will be one of our biggest yet – but on my way I’ve also swung by Oslo to visit my colleagues in the Social Media and Agenda-Setting in Election Campaigns (SAC) project which is now coming to its conclusion. While there I gave a couple of invited talks on my recent research – and the slides from those presentations are now available here.

First, I visited Anders Larsson at Westerdals Oslo School of Arts, Communication and Technology, where I outlined my thoughts on what …

The final speaker in this Social Media and Society session is Yuri Rykov, whose focus is on the Russian social network site V Kontakte. What is the structure of online communities on this site? Are they flat, inclusive, and egalitarian, or are they stratified and hierarchical, with clear leadership structures emerging, as a power law distribution would expect? What new light can network analytics shed on these questions?

Past studies have examined online communities such as Yahoo! Answers and Slashdot, and (somewhat controversially) researchers at the Pew Center have even proposed the existence of six archetypical structures in …

The next paper in this Social Media and Society session is by my QUT colleague Brenda Moon and me. Our work-in-progress presentation explores how we can connect our long-term data on the structures of follower networks in the Australian Twittersphere with shorter-term comprehensive information on actual posting activity; we are interested how follower networks and @mention networks cross-influence each other. What emerges already from our preliminary work is that different communities of Australian Twitter users appear to exhibit some very different activity patterns, and that some appear more likely to break out of their follower/followee network clusters than others. One …

The next session at Social Media and Society starts with Sílvia Majó-Vázquez, whose interest is in the role and positioning of legacy news media in social media spaces, for the particular context of Spain's media ecology. Some legacy news media have recognised their own difficulties in engaging with the online space; some are significantly decreasing their offline activities and therefore need to improve their online services by comparison.

To what extent are new outlets recognised as prominent sources of information by other news providers, then; to what extend do they act as information brokers, even? This addresses two dimensions of …

The final speaker in this Web Science 2016 session is Amaç Herdagdelen, whose interest is in the experience of immigrants using social networks. On Facebook, for instance, information about one's migrant status can be included in one's profile information; by identifying users with a difference between their stated home country and country of residence, the present study identified some 93 home countries with more than 10,000 immigrants on Facebook, for migrants in the U.S.

Additionally, it computed the exposure of users to friends with a migrant background, and calculated the relative exposure to various countries of origin; the …

The next speaker at Web Science 2016 is Onur Varol, who points out the wide variety of purposes for which people use social media, and notes that we change our online persona and usage styles according to different communicative contexts. Can we match language style and user intent, then?

The project's experiments found that messages written using logical arguments are perceived as more authoritative, while an absence of logical content makes the sender appear more likeable; the communication style also varies across different fields of interest (products, health, politics).

URL cascades tend to be more likely to involve relatively similar …
