Dr. Fattane Zarrinkalam is a Postdoctoral Fellow at the Laboratory of Systems, Software and Semantics (LS3) at Ryerson University, where she works on projects related to Semantic-enabled Social Network Analysis. During her PhD studies, she focused on the identification of social media users’ interests based on their individual and collective behavior on social networks especially Twitter. She has published her work in venues such as CIKM, ESWC and ECIR. In addition, she has published journal papers in premier journals including Information Retrieval and Information Processing and Management. Further, during her PhD, she was involved in four patent applications that were filed with USPTO and She has presented a tutorial on User Interest Mining from Social Media at SIGIR2019 and KDD2019.

Dr. Guangyuan Piao is a Research Scientist at NOKIA Bell Labs in Dublin, Ireland, where he works on research topics related to AIOps (AI for IT Operations) for communication systems. During his PhD studies at Insight Centre for Data Analytics at National University of Ireland Galway, he focused on semantics-aware user modeling and recommender systems in the context of social media. He has published his work in venues and journals such as UMUAI, CIKM, ESWC and Eurosys. He has been a reviewer for conferences such as ISWC, ESWC, and Middleware.

Dr. Stefano Faralli is an Assistant Professor at University of Rome Unitelma Sapienza, with the research interest in recommender systems, social media user interest profiling, ontology learning, distributional semantics, word sense disambiguation/induction and Linked Open Data. He did his PhD on Computer Science at the University of Rome Sapienza and he was a postdoctoral researcher at Data and Web Science Group University of Mannheim. The research results have been published and presented in highly relevant venues such as IJCAI, ISWC, JWS, ICDM and JSNAM. He co-organized the International Social Interaction-based Recommendation (SIR 2018@CIKM) and the International Workshop on Algorithmic Bias in Search and Recommendation (Bias 2020@ECIR).
