Today, I had the great pleasure of giving an introductory lecture on knowledge graphs at the #BILAI Summer School 2025 in Klagenfurt. Great energy and engagement!

Huawei research developed AutoSchemaKG, a knowledge graph generator producing 900+ million nodes and 5.9 billion edges. The schema is automatic and allows for incremental update. Interesting that they used Llama-3.1-8B-Instruct 🤔 https://arxiv.org/pdf/2505.23628 #KnowledgeGraphs #GraphDatabase

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 ;-)

Slide from the OWL slide deck of Information Service ENgineering 2025. An example for a nominal in OWL is depicted, i.e. a class that is defined by enumerating its members. The example is "MaddAddamTrilogyBook", which refers to a trilogy of novels by Margaret Atwood, It is defined to consist out of "Oryx and Crate, The Year of the Flood, and Madd Addam. The book covers of the three books are shown for an illustration.

New case study on how LLMs support knowledge graph creation for historical bookbinding:
“Stitching History into Semantics” presents BookBindKG, a Neo4j-based framework for documenting 19th-century Greek bookbinding with LLM-generated ontologies, Cypher queries, and semantic reasoning.

A graph database visualization showing a comprehensive bookbinding knowledge graph model with various nodes and relationships related to book attributes. The central node labeled "Book" is connected to multiple nodes representing different attributes, such as "Author," "Subject," and "TitleLanguage

Contextualise AI... this is what I have been working on for the last year or so: https://brettkromkamp.com/posts/contextualise-ai/

The core of the system is still graph-based. AI complements and even, to a degree, enhances, but does not replace... not even close.

Anyway, it's coming together.

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? ;-)

Example knowledge graph for the ISE 2025 lecture. The novels represented in this graph are:
- George Orwell: Nineteeneightyfour
- Harry Harrison: Make Room! Make Room!
- Octavia E. Butler: Parable of the Sower

Say Hi to team "Hobbit", who was awarded "Best Team" at ISWS 2025! Thank you so much for your engagement and enthusiasm!

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.

#isws2025 #summerschool #semanticweb #semweb #knowledgegraphs #AI #academiclife #PhD #bertinoro

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.

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!
