Photo of Ion Welcome to my web pages. I am Professor of Artificial Intelligence in the Department of Informatics of the Athens University of Economics and Business (AUEB), Director of AUEB's Information Processing Laboratory, and head of AUEB's Natural Language Processing Group. I am also Adjunct Researcher of the Institute for the Management of Information Systems (Digital Curation Unit) of the Research Centre "Athena", and Research Associate of the Institute of Informatics and Telecommunications (Software and Knowledge Engineering Lab) of NCSR "Demokritos". Before joining AUEB, I worked at the Institute of Informatics and Telecommunications of NCSR "Demokritos", and what is now the Centre for Language Technology of Macquarie University in Sydney. I received my PhD and MSc degrees from the University of Edinburgh, after graduating from the National Technical University of Athens.

My expertise is in Artificial Intelligence, especially Natural Language Processing. My current research interests include the following topics:

  • question answering, especially for biomedical document collections,
  • natural language generation from structured data, and more recently from medical images,
  • text classification, including filtering abusive content,
  • information extraction and opinion mining, including legal text analytics and sentiment analysis,
  • natural language processing tools for Greek,
  • machine learning in natural language processing, especially deep learning,
  • natural language processing in digital curation.

I co-organized the 1st Athens Natural Language Processing Summer School (AthNLP 2019), the EACL 2009 conference in Athens, the Large Scale Hierarchical Text Classification challenges (LSHTC3 was the ECML/PKDD 2012 Discovery Challenge), the BioASQ challenges, and the SemEval Aspect-Based Sentiment Analysis task (2014, 2015, 2016). In 2019, I received AUEB's Excellent Teaching Award for the academic year 2017-18. My group received a BioASQ award in 2018 for ranking first in three out of five document retrieval test batches and all five snippet retrieval test batches. We also received a BioASQ award in 2019 for ranking first in the four document and snippet retrieval batches we participated in. Our systems were also ranked at positions 1, 2, 3 and 5 among approximately 60 systems in the ImageCLEFmed Caption 2019 task, and at positions 1, 2, 6 among 49 systems in ImageCLEFmed Caption 2020 (see also this AUEB announcement).

Most of my publications are available on-line, some with accompanying software and datasets. My web pages also contain information on the research projects I am involved in, the courses that I teach, the student projects that I have supervised or that I propose, and ways to contact me. You can find more information about me in my CV (in English and Greek). If you need a break, you are welcome to visit my Flickr photostream.
