Comparing manually curated semantic mappings in SSSOM

I am currently supporting Philip Strömert and Noura Rayya in the efforts to modernize and revitalize the Chemical Methods Ontology (CHMO) to support annotation of instrumentation used to produce experimental data captured in the Chemotion electronic laboratory notebook as part of NFDIChem. This post is about the adoption of Simple Standard for Sharing Ontological Mappings (SSSOM) to support interoperability between CHMO and other resources, and the workflow I developed to compare overlapping manual curations from different researchers.

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.

Grounding AI the webby way — Taxonomy Boot Camp London 2026 takeaways

There was a heavy focus on artificial intelligence. But what really struck me was that the semantic approaches that are preparing us for our AI future are well-established web standards that have been around for decades.

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.
