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 …

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.

Brenda's work uses the TrISMA dataset of all tweets sent by Australian accounts over several years; this may miss tweets in a reply tree if …

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?

Twitter, for instance, provides a range of open APIs as well as commercial-quality data access via its subsidiary GNIP; the open streaming API offers up to 1% of the total global Twitter throughput, but potentially offers 100% of the tweets matching specific keywords or hashtags; and the open search API offers access to historical tweets, but also with …

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.

Within a two-week sample of Dutch tweets, the project identified the references to traditional and alternative media sources; the former represented established media including broadcasters, newspapers, and similar outlets, while the latter were often online-only, topic-focussed sites that were …

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?

We are able, of course, to measure aspects like …

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.

The Brexit 'Leave' campaign was slightly more active in its tweeting efforts; more users participated, and they were more active at tweeting. In the general election, Labour supporters turned out to be more numerous and more active. Leavers outtweeted Remainers by …
