Combating Online Scientific Misinformation
The drastic shift towards digital communication in our mediasphere has caused a profound change in the production and consumption of information, which in turn has substantial implications on the social and political landscape. Misinformation, as a side effect of mass information diffusion, has become a fundamental problem for governments, platforms, and the general public in light of critical events such as elections, pandemics, and wars. In this thesis, we focus on the problem of online scientific misinformation, proposing methods that tackle the problem at different granularity levels: at the level of claims, articles, and sources.
