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.

Our ISE team – Harald Sack, Tabea Tietz, Sasha Bruns, Ebrahim Norouzi & Sven Hertling – contributed with multiple talks and workshops on semantic technologies.
Highlight: The SemDH 2025 workshop on Semantic Digital Humanities
Keynote by Laura Hollink on Cultural Bias in Linked Open Data
Panel with Harald Sack & others
Proud to shape the future of
#KnowledgeGraphs & #DigitalHumanities!
Good Morning ESWC2025! The last conference day is about to start. Looking forward to an interesting keynote, more presentations and interesting discussions! Most interesting to see for me this year was the presence of neurosymbolic topics almost everywhere in our community.
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 
It was great that we could give our nanopublication tutorial yesterday at #ESWC2025. We recorded everything so you can watch and follow it here if you didn't have the chance to attend: https://nanopub.net/docs/tutorials/eswc2025program/
If you're at #ESWC2025 be sure to join tomorrow's Session 8 (16:00) with Robert David's talk on our joint work with Shqiponja Ahmetaj and Albin Ahmeti from Graphwise... Spoiler/crossing fingers: *nominated* as Best In-Use paper!

LLMs are starving for knowledge graphs. Raphael Troncy was pointing out that many LLM company crawlers are constantly visiting their KGs. Some crawlers even perform explicit SPARQL queries on the KGs.
In his keynote, Raphael Troncy is asking whether we should keep building knowledge graphs....taking into account 20 years of experience in building knowledge graphs

From this year on, ESWC will be under the umbrella of SWSA, the Semantic Web Science Association, to secure financial sustainability for the upcoming years after its previous supporting organisation STI was dissolved in 2023. Basics about the transition are given by Elena Simperl, president of SWSA.
ESWC 2025 has just started with the presentation of the submission numbers to the individual tracks:
research track: 98 papers
resource track: 36 papers
in-use track: 22 papers
Looking forward to great presentations and discussions!
Post workshop refreshment

The SemDH 2025 received lots of positive feedback from all of the people I spoke with. Very well done and kudos to the organising team: @tabea @srush_nlp Arianna Graciotti and Bruno Sartini! Looking forward to the workshop dinner tonight

Excellent keynote in the #SemDH2025 workshop by Laura Hollink on Cultural Bias in Linked Open Data. Laura is addressing all bias related aspects in cultural heritage items itself, in the data representing it, the data schemata, vocabularies, and ontologies on which the data are based, as well as in the knowledge representation languages used to create the schemata.

In his presentation "Exploring and Visualizing Italian Advertising Fliers and Posters through an Iconographical Lens with Linked Open Data" Bruno Sartini is demonstrating how to bridge traditional art historical methods with computational approaches by using structured iconographical data to empirically validate qualitative findings from cultural studies.

"Learn how to see. Realize that everything connects to everything else", but how to do this with Linked Data? Eero Hyvönen is quoting Leonardo Da Vinci as an intro to his presentation "How to Create a Portal for Digital Humanities Research Using a Linked Open Data Cloud of Cultural Heritage Knowledge Graphs: Case SampoSampo"

The 2nd SemDH 2025 Workshop is now live at #ESWC2025!
Room 4 – Adria I, Floor 11
SemDH brings together researchers working to bridge the gap between Semantic Web technologies and the evolving needs of the Cultural Heritage (CH) and Digital Humanities (DH) communities.
Our colleague Ebrahim Norouzi is presenting ConExion: Concept Extraction with Large Language Models, yoint work with Sven Hertling. Comprehensive Prompt Engineering Study of LLM-based concept extraction for domain coverage evaluation of ontologies.

The 2nd NSLP 2025 Workshop is now underway at #ESWC2025! Room 3 – Aurora III, Floor 0
NSLP brings together researchers focused on the processing, analysis, transformation, and utilization of scientific language and Research Knowledge Graphs (RKGs).
From papers to structured knowledge — this is where AI meets scientific publishing. 
Today the #SemDH2025 workshop takes place alongside #ESWC2025. I’m happy that Philipp Tögel will present our paper on Data-rich Web Annotations. We discuss how web annotations, a W3C standard, can be leveraged to include complex analysis with domain-specific data models as #LinkedData, without a need to extend the WADM core ontology. We apply this in @sfb1475 to store rich information about metaphorical expressions as annotations. https://semdh.github.io/accepted-papers#paper03 #DigitalHumanities #SemanticWeb
