Ten researchers from the Institute of Informatics & Telecommunications (IIT) at NCSR Demokritos took part in the 28th European Conference on Artificial Intelligence (ECAI 2025), held in Bologna, Italy, from 25–30 October 2025.
The IIT team included:
- Athanasios Davvetas from the AI Politeia research group
- Alexander Artikis and Manolis Pitsikalis from the CER research group
- Natalia Koliou, Stasinos Konstantopoulos and Christoforos Romesis from the DEG research group
- Theodoros Aivalis and Antonis Troumpoukis from the ID-IS research group
- Artemis Dampa from the INSANE research group
- Marilena Sinni from the ISL research group
Antonis Troumpoukis also served as the National Representative for Greece at the EurAI General Assembly and represented IIT at the AI-on-Demand Platform booth.
In addition, Nikos Katzouris was recognised as an outstanding Programme Committee member of ECAI 2025, being among the top 1.3% of the 2,253 PC members selected for this distinction. This is not the first time an IIT colleague has received such recognition and it reflects the institute’s continued contribution to the international AI research community.
During the main conference, Periklis Mantenoglou presented the paper “Sequencing in the Run-Time Event Calculus”, co-authored with Alexander Artikis, in the main ECAI technical programme. The work extends the Run-Time Event Calculus with sequencing capabilities, allowing the specification and recognition of more complex temporal patterns over streams of events, which is important for real-time monitoring and analytics in dynamic environments.
Furthermore, two IIT PhD candidates participated in the ECAI 2025 Doctoral Consortium, which offers the chance to present their work and receive feedback from peers and senior researchers.
-
Theodoros Aivalis – “Towards Interpretable Generative AI via Search and Knowledge Graphs”
His PhD work was in collaboration with the University of Glasgow, which received the Best Contribution Award for his presentation. -
Artemis Dampa – “Enhancing Scientific Research through Knowledge-Informed AI”
Beyond the main technical programme, IIT researchers were also actively involved in several ECAI 2025 satellite events, including workshops on data engineering, trustworthy AI and domain-specific AI applications.
DARES 2025 – Data Engineering and Reusability for Earth and Space Sciences
Antonis Troumpoukis co-organised the full-day Workshop on Data Engineering and Reusability for Earth and Space Sciences (DARES 2025) on 25 October 2025, held as a satellite event of ECAI 2025.
Organisers:
-
Antonis Troumpoukis
-
Iraklis Klampanos (University of Glasgow)
-
Manolis Koubarakis (National and Kapodistrian University of Athens)
The workshop focused on AI-driven data engineering for Earth and space science, including data integration, semantic enrichment, AI workflows, interoperability and open science. All papers and presentations are available on the workshop website.
IIT contributions at DARES:

TRUST-AI – Trustworthy AI
As part of the ECAI 2025 workshop programme, at the Trust-AI: European Workshop on Trustworthy AI (TRUST-AI), Athanasios Davvetas presented:
- TAI Scan Tool: A RAG-Based Tool with Minimalistic Input for Trustworthy AI Self-Assessment
Athanasios Davvetas, Xenia Ziouvelou, Ypatia Dami, Alexios Kaponis, Konstantina Giouvanopoulou, Michael Papademas
The TAI Scan Tool is a RAG-based self-assessment tool that helps evaluate AI systems against the EU AI Act, indicating risk levels and pointing to relevant regulatory articles. The work is currently available as a preprint on arXiv.
In addition to DARES and TRUST-AI, IIT researchers contributed to a range of ECAI 2025 co-located workshops covering biomedical data analysis and neuro-symbolic AI.
Tatiana Boura, Natalia Koliou and Christophoros Romesis gave several talks and poster presentations at specialised workshops:
