Use case: On top of the news with HPC Cloud
In a time when interference with elections and fake news are regularly making the headlines, a thorough analysis of media content is as welcome as it is relevant. At the University of Amsterdam (UvA), communication scientists are working on methods to gain better and more rapid insight into trends in the news.

Damian Trilling
"Our research can often be automated very easily, just by counting the words, but we are much further advanced in our work, for example using 'topic modelling', a method used to discover hidden semantic structures and machine learning. In this way, we can answer new questions.”
Online news
"A few years ago we started thinking about how to do this more efficiently and faster. All the newspapers are now available digitally, so automation was the obvious next step. In addition, there is a need for this type of research to be done on a larger scale. Analysis of the media goes beyond just analysing the newspapers. There are a number of other prominent channels in the provision of news online."
Answering new questions
The speaker is Damian Trilling (35), a university lecturer in the Political Communication & Journalism programme group at the UvA's Faculty of Social and Behavioural Sciences. "Our research can often be automated very easily, just by counting the words, but we are much further advanced in our work, for example using 'topic modelling', a method used to discover hidden semantic structures and machine learning. In this way, we can answer new questions.”
Prejudices and stereotypes
“As such, I am working with my colleague Anne Kroon on a project where we are looking at 15 years of reporting, and researching to what extent prejudices and stereotypes exist in relation to specific groups of migrants. In this research group there are many people working on subjects relating to populism. Or questions like: are press releases copied verbatim or, and this is much more interesting, not? Here you require a number of advanced techniques that, for example, can look reliably at the use of synonyms. What matters most to us is the relationship between the public, journalism and politics. There are some interesting cross-connections that can be made between them."
Greater demands
"We work in a faculty where traditionally we have not had much to do with IT. For average data sets of about 2,000 respondents, you can manage with SPSS and a laptop most of the time. That is why there is relatively little infrastructure available here. Our research is creating greater demands. That is why, a while back, I started looking for alternatives. Of course, you can obtain these commercially, but the HPC Cloud service from SURFsara was a more obvious choice, if only because it keeps the data in the Netherlands. That avoids jumping through a lot of legal hoops."
Differences between news sources
"My aim? To get a better understanding of how the news supply works. How people keep up to date with the news, what news actually is, and the differences between news sources. Also how we link the news to the user data, so that we can track how news is consumed. This of course has implications for privacy agreements. We recently had a discussion about the new legislation on data retention (GDPR). Security is essential, and that is something that is SURF can provide. As well as the practical functionality that we want, allowing data to be processed in an analytical environment and colleagues to log in remotely."
Hype detector
"Because we are detecting changes over the long term, our research is never over. Conclusions are, of course, published regularly. This yields a series of articles every year. We hope to complete the research into the differences in reporting on groups of migrants around the end of the year. In addition, we have just started up a little project that we call the 'hype detector', which we want to use to predict peaks in the news. But if you ask me what is at the heart of my motivation, then what I want is for communication science to continue searching for new ways to analyse data. Because otherwise we are always one step behind. Using old methods you can gain insight into a part of reality, but by no means all of it."
