Internet Technologies

Next at Web Science 2016 is Sergej Sizov, who focusses on the economic value of Web advertising. This is surprisingly difficult to calculate, and Sergej begins with the hypothetical example of a small Web advertising campaign. We may make a range of assumptions about click-through and purchase rates, but variance matters: in a substantial number of cases, campaigns may generate no profit whatsoever.

The next AoIR 2015 session I'm in has only two papers, as one speaker has dropped out at the last minute; the first speaker therefore is Fan Mai, whose focus is on the use of Virtual Private Networks and anonymising proxy servers in China. Some such servers are used especially by expatriates living in China, trying to access western media sites that are otherwise blocked.

The next speaker at AoIR 2015 is Smiljana Antonijević, whose interest is in the emerging field of the digital humanities. How did this field come to be imagined? It's founding story is generally associated with the Jesuit priest Roberto Busa and his interest in using digital technologies for information management; this gradually developed into humanities computing or linguistic computing. The arrival of personal computing further broadened this, and the term digital humanities finally emerged in the mid-1990s.

The next AoIR 2015 speaker is Stacey May Koosel, whose interest is in the temporalities of digital culture. She worked with articles to explore the concept of tl;dr (too long; didn't read) – in relation to our consciousness of time. Tl;dr is related to information overload, and emerged in 2003; it may point to decreasing attention spans, and show how we are overwhelmed by the information deluge we are now faced with. We negotiate it by employing pattern recognition.

The next session at AoIR 2015 is exploring timing issues, and the first paper by Sarah Muñoz-Bates is about the effects of Google on how people perceive topics. For example, what is the effect of seeing the term 'illegal' rather than 'undocumented' in relation to migrants? Does it cross the line and criminalise the person; is it racialised in a way that other terms are not?

We are now inviting applications for the 2016 CCI Digital Methods Summer School. The deadline for application is Monday 21 Sep. 2016.

Hosted by the QUT Digital Media Research Centre (DMRC), the 2016 event will focus on digital methods for sociocultural research. It is designed for university researchers at all stages of their careers, from doctoral students, postdoctoral and mid-career academics to established scholars.

The week-long intensive program will focus on new quantitative, qualitative and data-driven digital methods and their research applications in the humanities and social sciences, with a particular focus on media, communication and cultural studies and their applications in the creative industries.

Participants will work with leading researchers, engage in hands-on workshop activities and will have the opportunity to present and get feedback on their own work.

The Summer School will offer a range of introductory hands-on workshops in topics such as:

• Digital ethnography
• Issue mapping
• Social media data analytics
• Software and mobile app studies
• Analysing visual social media
• Geo-spatial mapping
• Data visualisation
• Agent-based modelling
• Web scraping

The program will be conceptually grounded in the problems of public communication and privacy, digital media production and consumption, and the ethical issues associated with big data and digital methods in the context of digital media environments. There will be talks on these topics in addition to the workshops.

The next speaker at AoIR 2015 is Michael Stevenson, whose focus is on what he calls new media "rupture-talk". The idea here is to take what we often refer to as "mere talk" more seriously. Michael points to John Perry Barlow's "Declaration of the Independence of Cyberspace" as an example of this – new media as a radical break from the past.

The concept of cyberspace has been on the decline since its heyday in the mid-1990s, even in major booster publications like Wired. But other rupture-talk concepts, such as MOOCs or the "social graph" have emerged, and are also used to signify a radical break from the immediate past. Such terms are often understandably criticised as hype (Evgeny Morozov's The Net Delusion is an obvious example).

The final speakers in this Digital Methods plenary are Axel Maireder and Katrin Jungnickel, whose interest is in the uncertainties of the Facebook timeline. Facebook has continued to tinker with how the timeline is selected and presented for several years now, and this affects the flow of communication on the platform; what, then, are the factors which determine that flow?

This study combined content analysis and user surveys, but both these approaches have their drawbacks - it is impossible from the outside to track the content of users' timelines, for example, but surveys of users also suffer from self-reporting biases. In the end, the researchers asked users to copy the links they received through their timelines into an online survey, and to discuss the content of the URLs and the Facebook friends they received them from. Issues with privacy as well as the tedious nature of this approach also affect the results, however. Some 550 users participated in the study.

The next plenary speaker at Digital Methods is Martin Emmer, whose focus is on sampling methods in digital contexts. Online media are now important public fora, and conventional media are increasingly using digital channels to transmit their content as well; this also leads to a shift in media usage, of course, and some of that shift is also driven by generational change.

If we need to examine the digital space to understand current debates in the public sphere, then, how do we generate representative samples of online content and activities? With traditional mass media, it was possible to draw on comprehensive lists of media providers, with a small handful of alternative media; in the digital environment, channels and platforms have multiplied massively, and it is no longer trivial to select a small number of sites and spaces which represent all online activity.

The next session at Digital Methods is a plenary panel which begins with Christina Schumann, whose focus is on Google and other search engines as technological actors on the Internet. Search engines are especially important as they now serve as a kind of gatekeeper on the Net - but the criteria they use for ranking and structuring information are often far from transparent.

The basic approach of search engines is to crawl or otherwise gather Internet data which are then indexed and processed into a database; this database is queried as a search query is entered into the search engine. Factors in returning search results include on-page information (content, programming, and design of Web pages) as well as off-page metadata (especially the link networks surrounding each page, relative to the theme of the query).
