You can search for articles that cite my publications via Google Scholar or Semantic Scholar. Some of my publications are accompanied by publicly available software and/or datasets (see below). See also the Software and Data page of AUEB's Natural Language Processing Group.

In 2024, I edited a special issue of AUEB's newspaper (OPA News) on Artificial Intelligence and Large Language Models, which was published in two parts (part A, part B) included in the Greek newspaper To Vima.
