Detecting and countering disinformation grows increasingly important as efficient disinformation campaigns lead to negative real-world consequences on a global scale, both in politics and in society. Machine learning (ML) methods have demonstrated their potential for at least partial automatisation of disinformation detection and analysis. In this report, we review current and emerging artificial intelligence (AI) methods that are used or can be used to counter the spread and generation of disinformation, and briefly reflect on ongoing developments in anti-disinformation legislation in the EU. This overview will shed light on some of the tools that disinformation-countering practitioners could use to make their work easier.
