Automatic Detection of Online Disinformation: Major Challenges Ahead
Ubiquitous online mis- and disinformation pose serious threats to society, democracy, and business. This talk first defines the technological, legal, societal, and ethical dimensions of this phenomenon. It also presents current understanding in why people believe false narratives, what motivates their sharing, and how they might impact offline behaviour (e.g. voting). The talk then summarises state-of-the-art technological approaches to fighting online disinformation. It follows the AMI conceptual framework (Agent, Message, Interpreter), which considers the origin(s) and the impact of online disinformation alongside the veracity of individual messages. In conclusion, major outstanding socio-technical and ethical challenges are discussed.
