🤠 #KDAI2026 final lecture on #KnowledgeGraphs 04 & #NeurosymbolicAI

The final graph session, then the leap to hybrid AI:

▸ OWL — complex classes & property restrictions
▸ SHACL Shapes
▸ Neurosymbolic AI with KG embeddings, RAG,
▸ AI limits revisited (ELIZA, Clever Hans, Chinese Room, Turing Test, the paperclip maximiser & the singularity).

Neither symbols nor learning alone get us there. 📡 SEE YOU SPACE COWBOY…

This Stanford #HCI seminar,
Toward Ontological Multiplicity…
Begins naming the challenge (I might go so far as to call it the visceral pain I feel) with language. It defines #ontologies as
"what we allow ourselves to think or talk about, or deem possible."
Translating abstract thought into language just requires such loss. Speech just naturally seems to require an element of grief over how little can be communicated.

🌐 Join Our Team: Shape the Future of Neurosymbolic AI & Knowledge Graphs! 🚀
We are looking for a PhD/Junior Researcher or PostDoc/Senior Researcher with research interest in neurosymbolic AI, knowledge graphs, ontologies, and large language models to work with us in the Platform MaterialDigital project.

The new #KDAI2026 lecture is out. How to get from a sentence to something a machine can actually reason?

The greenhouse effect was discovered by Fourier, explained by Eunice Newton Foote. 3 words, 1 triple: subject, predicate, object. Stack enough of them and you get a graph. Add an ontology and the machine starts to infer.

This session:
▸ Graphs & triples
▸ #KnowledgeGraphs & #ontologies
▸ #SemanticWeb & #LinkedData
▸ #RDF, RDFS, #SPARQL, #OWL, #SHACL

LintedData 3.0.0 is released:
➡️ https://gitlab.com/dlr-dw/linteddata/-/releases/v3.0.0

LintedData is a linter for RDF and Ontologies for easy use in CI pipelines. It checks for common violations of best practices in ontology engineering.

Version 3.0.0 enables checking of multiple RDF files with one execution, reduces the need for configuration, and improves or fixes many checks.

A quick #introduction using an obscene number of hashtags to hopefully reach people I want to be in community with! I make #art and #software and particularly like #linocuts and #embroidery and I also enjoy #visiblemending.

On the tech side my pet topics are currently #datavis (currently looking at #publictransport in my area) and #rdf #ontologies (what can we practically and ethically do with them?)

Would love to follow you if you're interested in any of these things.

Already yesterday, I presented at the ESWC 2026 Pre-Conference in the Knowledge Graphs for Sustainability Workshop (KG4S) the Design-for-Circularity Ontology (D4CO). Related artifacts are available online.

Good morning Dubrovnik! ESWC 2026 - the 23rd European Semantic Web Conference is starting today. Looking forward to visionary and inspiring keynotes, presentations, and posters, esp. addressing the question on how #SemanticWeb technologies will survive (or even prevail...) the current 3rd wave of #AI

Recently, I was discussing about the pros and cons of different unit ontologies. However, I was not able to really express, why I am in favor of an ontology, which not only provides the direct conversion factors between units for direct application, but also provides the explanation for these values. In her keynote, Maria-Esther Vidal provided an explanation for my intuition (free after Aristotle): "We think we know a thing only when we know its cause." #eswc2026 #UnitsOfMeasurement #Ontologies

After today's #KDAI2026 lecture on "Basic Machine Learning 01", you will understand why most of what people say about AI in public debate is either wrong, confused, or missing the point — and you will have the tools to do better. If you've ever wondered how Netflix predicts your next binge-watch or how self-driving cars navigate, this is where it all starts.

How to model temporal aspects and temporality in RDF, esp. in the domain of cultural heritage?
Our newly published paper "Temporal Modelling in Cultural Heritage Knowledge Graphs: Use Cases, Requirements, Evaluation, and Decision Support" by @sashabruns @joerg Jeff Pan and @lysander07 in Transactions on Graph Data and Knowledge will provide you some answers 🎉

Finto is getting an refresh - new Super Finto in trial use from April 1st! 🚀

Super Finto offers an unprecedented user experience for exploring YSO concepts, taking ontology browsing to a new level! Visualized concepts help you navigate the hierarchy, you learn to effortlessly distinguish preferred terms from non-recommended ones, and persistent IDs ease information retrieval. Multilingual support is built-in.

Try it: https://osma.github.io/super-finto 🤩

A quick 2 second search on file system #ontologies did not directly yield a great standard candidate, but it did return some interesting results on #SemanticFileSsystems.

Like this paper and #ontology design:

Two intense days at the NFDI-MatWerk All-hands-on-Deck meeting in Siegburg! Huge kudos to the organising team for making it so fruitful. Loved connecting with the MatWerk community, reflecting on Phase 1 achievements and getting excited for Phase 2. Big shoutout to the @fizise team: @enorouzi @heikef Hossein Beygi Nasrabadi and Alsayed Algergawy!

The OntoWeaver team is proud to release version 1.4 of its tool 🥳

OntoWeaver allows to easily parse iterable data (like tables or documents) and create a Semantic Knowledge Graph. Basically, you write a simple YAML file telling what data you want to be a node or a property, you call a generic command, and 🎉 , you have your graph ready.

With the 1.4 series, the main new feature is an option to display progress bars when doing heavy processing (like loading large CSV files).

The documentation has also been heavily updated, completed and polished:
