Today in the ISE 2025 lecture on OWL, the Web Ontology Language. Tired of using slide presentations (at temperatures like today and giving the same presentation all over again), I spontaneously decided to design arbitrary OWL ontologies together with the students on the good old blackboard ;-)

Tomorrow, we will dive deeper into ontologies with OWL, the Web Ontology Language. However, I'm doing OWL-lectures now for almost 20 years - and OWL as well as the lecture haven't changed much. So, I'm afraid I'm going to surprise/dissapoint the students tomorrow, when I will switch off the presentation and start improvising a random OWL ontology with them on the blackboard ;-)

In today's ISE 2025 lecture,, we will introduce SPARQL as a query language for knowledge graphs. Again, I'm trying out 'Dystopian Novels' as example knowledge graph playground. Let's see, if the students might know any of them. Wtat do you think? ;-)

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.

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!

We are being photographed by Frank van Harmelen :)

Selfie time at ISWS, 2nd day minute madness. What else should you do, if you have 45 seconds time to introduce your poster and have some spare time left ;-)

Now, research task forces are working hard on their research problem for the week.

Oh yes, this summer school is so stressful .... that we decided to offer a yoga class each morning before diving back again into "serious" research. But first things first: shavasana for all :)

ISWS running club at halfway turning poing. Now we've run (easily) downhill for 3km and are about to climbing up again ... same like the ups and downs in the research life cycle ;-)

Was Michelangelo really a turtle?
This question will be solved by the research task force of @lysander07 who is presenting this LLM question answering and Information Extraction task, in which the reliability of LLMs applied on historical documents will be analysed.

Aidan Hogan from University of Chile is introducing the ISWS 2025 students to (large) knowledge graphs and is asking to extend Wikidata by adding all our profiles to it.

The first ISWS 2025 Tutorial Session is on "Reasoning in Large Knowledge Graphs". Valentina Presutti is announcing Aidan Hogan from University of Chile, Santiago de Chile, as first speaker.

"Ceci n'est pas sémantic"
Frank van Harmelen is alluding to the famous Réné Magritte painting "Ceci n'est pas une pipe" pointing out the the knowledge graphs we are using frequently don't carry any semantics at all, but are only "nicely" structured graphs.

Are you ready? Bertinoro castle is waiting for you! Tomorrow, the 2025 edition of the International Semantic Web Research Summer School is about to begin. We are waiting for 60 graduate students, all eager to become a researcher in the field.

Please post a hi if you are attending this year (or have attended in the past...)

Last preparations for the upcoming International Semantic Web Research Summer School 2025, before traveling the last leg of the journey from Bologna to Bertinoro tomorrow.

Catching up with dear old friends and colleagues at the #eswc2025 welcome receiption yesterday evening. With more than 270 participants the conference already is a big success! I met Claudia d‘Amato for the first time back in 2005 or 2006 at an Italian Semantic Web Conference in Trento
