Back in the lecture hall again after two exciting weeks of #ESWC2025 and #ISWS2025. This morning, we introduced our students to RDF, RDFS, RDF Inferencing, and RDF Reification.

Slide from the ISE 2025 lecture on Resource Descriptiuon Framework (RDF) as simple data model. The slide is showing a small knowledge graph, indicating that Climate Change was explained by Eunice Newton Foot in 1856 as well as by John Tyndall in 1859. To represent this n-ary (multi-valued) relations, we are using so-called blank nodes, representing an "explanation" each, which bundles the discoverer and the discovery date. This is done via "dereferencable" blank nodes here.

Students discussing (and probably some random tutors further back) during lunch break on the terrace of Bertinoro castle, last week.

The terrace at BErtinoro castle. There is a buffet which had already started previously. We can see some cookies, fruits (probably apricots) and a huge bowl of salad besides lots of plates and water bottles. Three students are discussing in the foreground while having lunch. In the background we can see more students (already seated) together with some assistant tutors and tutors, all in conversation while having lunch.

The #ISWS2025 experience really managed to combine lots of fun activities and challenges (that we took an oath to keep secret 🤫), working with leading figures of the Semantic Web field as well as intense networking in a unique, wonderful way! It felt like a month worth of program items and activities had been compressed to one magnificent piece of art.
During the last week, among many other things, I
- summarized the motivation of my work in a 45s "Minute Madness" session

It's a wrap! ISWS 2025 was a huge success! 60 wonderful students, 5 brilliant assistant tutors, 11 extraordinary tutors, 3 magnificent keynoters, and 2 visionary & unassuming directors. We've had a great time together with all of you and hope, you've had a safe trip home!

Memories from the last night gala dinner, selfie with some of the ISWS 2025 tutors. It was such a great time! We are missing you all already!

Without you this summerschool would never have been possible! You've did a marvellous job! Thank you so much!!!

#isws2025

Today marks the end of #isws2025. I am really happy to have attended the summer school and I can only recommend everyone with an interest in the semantic web to do the same. I also have a little 🥳 , I got awarded the best poster award. I am really happy with this reward, as it confirms the novelty of my research and my views on the needs of decentralised data ecosystems.

If anyone wants to discuss, please do reach out. The poster can be found at: https://jitsedesmet.be/posters/2025-phd-symp.pdf

Was Michelangelo really a Turtle? ... was one of the questions that team Vulcan was treating in their research on Information Extraction on historical documents on the example of Giorgio Vasari's "The Lives of Excellent Painters, Sculptors, and Architects...."
