Ion Androutsopoulos

Ion Androutsopoulos is a Professor in the Department of Informatics at Athens University of Economics and Business (AUEB), where he leads the AUEB NLP Group. With over 180 publications spanning three decades, he is a prominent figure in Natural Language Processing research, particularly known for his work bridging NLP with legal informatics, Greek language processing, and biomedical applications.

His research interests focus on several interconnected areas of Natural Language Processing:

• Legal Informatics: developing NLP systems for legal document analysis, legal judgment prediction, and legal reasoning, with recent work including GreekBarBench and Archimedes-AUEB systems
• Greek Language Technology: creating specialized tools for Modern Greek processing, including GR-NLP-TOOLKIT and Greeklish transliteration systems
• Biomedical Text Mining: working on diagnostic captioning and medical image analysis through participation in ImageCLEFmedical challenges
• Financial NLP: developing systems like EDGAR-CRAWLER for financial document analysis and XBRL tagging

His recent publications (2023-2025) show an increasing focus on Greek-specific NLP resources and practical applications of large language models in legal reasoning. His work often combines theoretical NLP advances with practical implementations, particularly through his leadership of the AUEB NLP Group which regularly participates in international evaluation campaigns.

Professor Androutsopoulos has supervised numerous PhD students who have become active researchers in their own right, including John Pavlopoulos, Prodromos Malakasiotis, and Ilias Chalkidis. His collaborative network spans multiple institutions and disciplines, reflecting the interdisciplinary nature of modern NLP research.
