The next speaker at AoIR 2017 is Olga Boichàk, who begins by highlighting the role of social media platforms in structuring specific forms of human sociality. But this also means that automated accounts – specifically, bots – can imitate and affect genuine human interactions in these spaces. What does this mean for online discussions in the context of the 2016 U.S. election campaign, then?

The first keynote at AoIR 2017 is by Andrew Chadwick, who explores what the 2016 U.S. presidential campaign means for our understanding of the hybrid media system. Political communication is in the middle of a chaotic transitional period, due in good part to the disruptions brought by newer, digital media; some older media have also been renewed by integrating the logics of newer media. This then represents a systemic perspective that examines forces while they are in flow.

The hybrid media system is built on the interactions of older and newer media logics in the reflexively connected field of media and politics. Actors in this field tap and steer information flows in ways that suit their goals, enable or disable the agency of others, across various older and newer media settings. 'Hybrid' here shifts our conceptualisation from 'either/or' to 'not only, but also'; it foregrounds complexity, interdependence and transition. We pay more attention to boundaries, flux, and liminal spaces, where practices intermeshing and co-evolve.

The next speaker in this AoIR 2017 is my DMRC colleague Brenda Moon, whose focus is on reply chains on Twitter. There are a number of ways in which replies are chained together, and in fact the term 'reply tree' may be preferable to 'reply chains': there may be many replies to the same original tweet only, or a long dyadic interaction over a series of tweets, or various permutations between these two extremes.

The next speaker in this AoIR 2017 session is Rebekah Tromble, whose focus is on the impact of digital data collection methods on scientific inference. Collecting data from social media APIs, how can we know whether we have 'good', valid data?

The second paper in this AoIR 2017 session is by Daniela van Geenen and Mirko Schäfer, whose focus is on 'fake news' on Twitter. They began by tracking activities in the Dutch Twittersphere, and identified a number of communities within this userbase; within these communities, news and other information are being shared, and a process of social filtering takes place.

I'm the next presenter in this Future of Journalism 2017 session, and my presentation is below. A full paper is also available here.

The third presenter in this Future of Journalism 2017 session is Shannon McGregor, whose interest is in the role of social media in the construction of public opinion by the political press. There's an increasing tendency for journalistic coverage to claim that 'Twitter' or even 'the Internet' responded in a particular way to specific political issues and controversies, and social media certainly play a role in how public opinion is shaped, but how might we think about the type of public opinion that can be observed on social media?

The first paper session at Future of Journalism 2017 starts with Max Hänska, whose focus is on the role of social media in political debate during Brexit and the 2017 U.K. general election. Max's study tracked tweets including a set of keywords for both events, as well as following the Twitter accounts of some 2,100 candidates in the election.
