Do not blame it on the algorithm: an empirical assessment of multiple recommender systems and their impact on content diversity external link
Abstract
In the debate about filter bubbles caused by algorithmic news recommendation, the conceptualization of the two core concepts in this debate, diversity and algorithms, has received little attention in social scientific research. This paper examines the effect of multiple recommender systems on different diversity dimensions. To this end, it maps different values that diversity can serve, and a respective set of criteria that characterizes a diverse information offer in this particular conception of diversity. We make use of a data set of simulated article recommendations based on actual content of one of the major Dutch broadsheet newspapers and its users (N=21,973 articles, N=500 users). We find that all of the recommendation logics under study proved to lead to a rather diverse set of recommendations that are on par with human editors and that basing recommendations on user histories can substantially increase topic diversity within a recommendation set.

“Reformist Departure”: Questions Referred by the Bundesgerichtshof to the CJEU on the Reporting of Current Events and Quotation Exceptions external link
Abstract
The exceptions for reporting of current events and quotation facilitate the functioning of the media. On 27 July 2017, the Bundesgerichtshof (BGH) submitted several questions to the Court of Justice of the EU (CJEU or Court) on the balance between copyright exceptions and the fundamental freedoms of information and the media, as well as the exceptions for quotation and reporting of current events. In answering these questions, the CJEU may well shed light on the open-ended drafting of these exceptions.

Online Political Microtargeting: Promises and Threats for Democracy external link
Abstract
Online political microtargeting involves monitoring people’s online behaviour, and using the collected data, sometimes enriched with other data, to show people-targeted political advertisements. Online political microtargeting is widely used in the US; Europe may not be far behind. This paper maps microtargeting’s promises and threats to democracy. For example, microtargeting promises to optimise the match between the electorate’s concerns and political campaigns, and to boost campaign engagement and political participation. But online microtargeting could also threaten democracy. For instance, a political party could, misleadingly, present itself as a different one-issue party to different individuals. And data collection for microtargeting raises privacy concerns. We sketch possibilities for policymakers if they seek to regulate online political microtargeting. We discuss which measures would be possible, while complying with the right to freedom of expression under the European Convention on Human Rights.
