    Misinformation (Fake news, rumors, etc.) and hate speech detection on online social platforms - University of Tartu, Estonia (Partner for Project)

    Computational social science group (, at the University of Tartu, Estonia, lead by Dr. Rajesh Sharma, is actively working in the domain of Misinformation (Fake news, rumors, etc.) and hate speech detection on online social platforms. Specifically, the group has analysed misinformation detection on YouTube, Tweeter, and other publicly available datasets. We have specifically applied techniques related to AI (classical machine learning and state of the art deep learning techniques, including graph neural networks), Knowledge Graph, Network Science (Social Network Analysis), and Natural Language Processing.

    Group is part of EU H2020 project SoBigData and CHIST-ERA SAI.
