Scholarship Selection Meeting for DEAI Project
Katja Hose has participated in the selection process for the first cohort of Erasmus Mundus scholarship recipients for the Joint Master in Data Engineering & Artificial Intelligence (DEAI), which will launch in Fall 2026.
Following a two-day selection meeting held in Barcelona, representatives from UPC, ULB, TU Wien, Padova, and Lyon 1 jointly reviewed close to 3,000 applications from candidates worldwide. From this highly competitive pool, 25 scholarship holders were selected for the first intake of the programme.
The selection process benefited from close collaboration across the partner institutions. Many thanks to Oscar Romero and Montse Jándula for organizing the meeting, and to Dimitris Sacharidis, Massimiliano de Leoni, Andrea Mauri, Gerard Pons, and Sophie Azarm for the constructive and thorough discussions.
The overall quality and motivation of the applicants were exceptionally high, underlining the strong global interest in advanced training in data engineering and artificial intelligence.
This milestone marks an important step towards the launch of DEAI in Fall 2026. The consortium is now moving into the final phase of programme preparation.
We look forward to welcoming the first DEAI students.

PhD Defense in Amsterdam Event
Katja Hose served on the examination committee for the PhD defense of Effy Li at the University of Amsterdam.
Effy's thesis ("A Paradigm Shift in Knowledge Graph Construction") studies a shift in knowledge graph construction from fine-tuning toward prompt-based workflows with large language models and was supervised by Paul Groth and Jan-Christoph Kalo.
Congratulations to Effy on this significant achievement!

Keynote at EGC 2026 Presentation
Katja Hose gave a keynote at EGC 2026 on "Reliable Knowledge in the Age of Generative AI: From Noisy Data to Trustworthy Agents".
The talk reflected on the role of knowledge graphs and data quality in the age of generative AI, and on why reliable, structured knowledge remains essential for hybrid systems that combine symbolic knowledge with generative models. It also touched on hallucinations and on how these foundations relate to agentic systems.
Thank you to Fatiha Saïs for the invitation, and to the organizing team for a well-run conference. Many thanks as well to the audience for the thoughtful questions and discussions.
