Stergios Chatzikyriakidis

Stergios Chatzikyriakidis is a Professor of Computational Linguistics at the University of Crete. He earned his BA in Greek Philology (specializing in Linguistics) from Aristotle University, Thessaloniki. He continued his studies with an MSc in Computational Linguistics and Formal Grammar and a PhD in Linguistics, both from King’s College, London. He has worked at Royal Holloway, University of London, the French National Centre for Scientific Research (CNRS), the Open University of Cyprus, and the University of Gothenburg. From 2016 until 2021, he was the Associate Director of the Center for Linguistic Theory and Studies in Probability (CLASP). 

He is an expert on computational semantics and has dealt with a number of computational semantics tasks (nowadays referred to as Natural Language Understanding), such as Natural Language Inference, Paraphrase Detection, and Sentiment Analysis, among others. He has also worked on solving these tasks using a variety of techniques, from old school, good ‘ol AI symbolic approaches to probabilistic and Machine Learning/Deep Learning ones. Furthermore, he has been interested in issues that touch on the generalization and explainability capabilities of DL models, pointing out issues and problems related to annotation artefacts and other biases that can produce misleading model performance. Lastly, he is an expert on formal syntax and formal semantics and has produced a number of papers on core issues in Greek syntax and formal semantics (including one monograph in formal semantics). He has more than 70 publications (including two monographs) and more than 90 conference participations. In TALOS, he is the NLP expert, member of the UoC committee, and the co-leader of RT.3 (Corpora Analysis using NLP). For a detailed cv, please see here.
