Yesterday, I've attended the MSE Research Data Forum 2025 organised by #NFDIMatWerk. Aside from the conference presentations, our little ontologies group was meeting and discussing future work on ontologies in NFDI-MatWerk, including NFDIcore, MatWerk Application Ontologies, and PMDcore.

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 ;-)

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.

In this blog post at https://s.gwdg.de/m5Bu3L I showcase the #NFDI4BIOIMAGE (@nfdi4bioimage, @nfdi4bioimage@bird.makeup) #knowledgegraph and its function as a registry for public #OMERO image data repositories and their respective #SPARQL endpoints. Annotated #bioimage data has become part of the #semanticweb. @joshmoore @Andrawaag #nfdi #metadata #KnowledgeGraphs #ontop #r2rml #rdf
Linked Open Data for Bioimaging

This post demonstrates the NFDI4BIOIMAGE Knowledge Graph (N4BIKG). Many aspects of this project are still very much in the flow including a consensus on which ontologies and terms to employ, how to define various namespaces and much more. These issues left aside, I focus on two components: First, the "core" KG contains information about the NFDI4BIOIMAGE consortium, it's participating institutions and people working in or for NFDI4BIOIMAGE, publications (via zenodo records submitted to the NFDI4BIOIMAGE community) and some more.

Maria Chudnovsky reflects on her journey in graph theory, her groundbreaking solution to the long-standing perfect graph problem, and the unexpected ways this abstract field intersects with everyday life.
