The design of modern machine learning systems should take into account not only their effectiveness in solving a given problem, but also their impact on the rights of individuals. Implementing this goal may involve applying technical solutions proven in the IT industry, such as event logs or certification frameworks.

Recommendation algorithms potentially amplifying extremist content has become a policy concern in recent years. We conduct a novel empirical experiment on three platforms (YouTube, Reddit, and Gab) to test this phenomenon. We find that YouTube’s “Recommended for you” system does promote extreme content. We synthesise the findings into the policy debate and argue that co-regulation may provide some solutions.

This research investigates EU member states’ preferences and coalitions in recent negotiations of the Council of the EU related to the digital single market.

This article belongs to Concepts of the digital society, a special section of Internet Policy Review guest-edited by Christian Katzenbach and Thomas Christian Bächle. 1. Introduction The concept of decentralisation traverses multiple contexts, fields and disciplines. We begin this multidisciplinary discussion on decentralisation with describing the technical definitions and motivations for decentralisation in network engineering. We then move on to discuss the broader motivations for such decentralised networks, which span social, political and economic aims. Our intention is not to compare cases of decentralisation across disciplines and contexts as much as to point out that a study of …

A cryptocurrency system can be understood as a system intended for the issuance of tokens which are intended to be used as a general or limited-purpose medium-of-exchange, and which are accounted for using an often collectively-maintained digital ledger making use of cryptography to replace trust in institutions to varying extents. Against such a backdrop, the singular term cryptocurrency can mean a token, intended to be used as a general or limited-purpose medium-of-exchange, issued via a cryptocurrency system.

The rapidly evolving blockchain technology space has put decentralisation back into the focus of the design of techno-social systems, and the role of decentralised technological infrastructures in achieving particular social, economic, or political goals. In this entry we address how blockchains and distributed ledgers think about decentralisation.

Once again platform liability: on the edge of the ‘Uber’ and ‘Airbnb’ cases

The CJEU judgements in the ‘Uber’ and ‘Airbnb’ cases may help to determine whether platform operators bear liability towards platform customers and on what grounds.
