Anastasia Giachanou
Misinformation Detection in Online Social Networks
PRHLT Research Center, Universitat Politècnica de València (UPV), Spain

Misinformation is one of the most critical challenges of recent years. Despite all the attempts, the automatic detection of misinformation still remains an open problem. Although misinformation and fake news exist for a long period of time, the ubiquitousness of social media has facilitated their propagation with severe consequences for the society. This talk will focus on the topic of misinformation detection. First, I will introduce the concept and characteristics of the different types of misinformation and disinformation such as fake news, satire, rumours that go viral in online social networks. Then, I will present some of the most recent detection approaches with a particular focus on approaches that exploit psycho-linguistic information (i.e., emotion, sentiment, informal language). Also, I will present approaches that exploit information extracted from user profiles and user interactions. Finally, I will discuss challenges and open issues in the field of misinformation detection.

Anastasia Giachanou is a Research Fellow at the Pattern Recognition and Human Language Technologies (PRHLT) Research Center at the Universitat Politècnica de València (UPV) and a member of the Natural Language Engineering Lab headed by Prof. Paolo Rosso. She received her PhD from the Faculty of Informatics at the University of Lugano, in Switzerland working on the topic of “Tracking Opinion Evolution on Social Media”. Her research interests include fake news detection, credibility in news, bot detection, sentiment and emotion analysis, temporal opinion mining and information retrieval. She serves on the editorial board of Information Processing & Management Journal and as a PC member for well-established conferences such as SIGIR, ECIR, CIKM, and ECAI. She is a recipient of an Swiss National Foundation (SNF) early post-doc grant on the project "Early Detection of Fake News on Social Media".

Julio Gonzalo
Bias in Information (tentative)
Natural Language Processing and Information Retrieval Group, UNED, Spain


Julio Gonzalo is full professor at UNED (Universidad Nacional de Educación a Distancia, Spain), where he leads the Research Group in Natural Language Processing and Information Retrieval ( His current research interests include Evaluation Metrics and Methodologies, Semantic Textual Similarity, Online Reputation Monitoring and Information Access Technologies for Social Media. He has co-chaired evaluation activities such as RepLab (for Reputation Monitoring tasks), WePS (Web People Search) and iCLEF (interactive Cross-Language search and Question Answering). In this context, his research made a special emphasis on the formal assessment of evaluation metrics, which led to a Google Faculty Research Award (with Stefano Mizzaro and Enrique Amigó) in 2012. He has recently been appointed as general co-chair for the ACM SIGIR 2022 Conference. His publications cover many topics at the intersection of IR and NLP, and can be found here.
