TOOL: ResearchSpace 4.0.0 is an open-source platform that leverages knowledge graphs to integrate narratives and data, enhancing the contextualization of cultural heritage research. By employing semantic expressions and ontologies like CIDOC CRM, it allows for dynamic and interconnected representations of complex historical information. Could this be the future of digital humanities research?

Data graphs, computation graphs, property and #knowledgegraphs, #graphdatabase, probabilistic graph models, #gnn, there is currently an explosion of terms involving "graphs". What are their relations if any?

The Open Risk Academy course "An overview of graph methods in #datascience " aims to put some order in the graph chaos by introducing and relating these concepts in a structured way, resulting in, you've guessed it, a "graph of graphs"!

A graph diagram offering a systematic arrangement of different terms using in data science that include the term "graph". Concepts are represented as nodes and the links imply a derived relatioships (subclass). This becomes thus a graph of graphs!

Skills that Rebecca Schneider learned in library science school - #taxonomy, #ontology, #semanticModeling, and #metadata - have only become more valuable with the arrival of AI technologies like LLMs and the growing interest in #knowledgeGraphs.

Two things have stayed constant across her library and enterprise content strategy work: organizational rigor and the need to always focus on people and their needs.

Poster from our colleague @epoz from UGent-IMEC Linked Data & Solid course. "Exploding Mittens - Getting to grips with huge SKOS datasets" on semantic embeddings enhanced SPARQL queries for ICONCLASS data.
Congrats for the 'best poster' award ;-)

Very nice poster "Getting the Grips with huge SKOS datasets" - Exploding mittens. Exploding Mittens - Getting to grips with huge SKOS datasets Creators: Posthumus, Etienne The ICONCLASS classification system contains more than 1 million SKOS nodes in English, German, French, Italian, Portuguese, Japanese, Dutch, Polish and Czech- in short a non-trivial large corpus of Linked Data. It is possible to load the data into performant triplestores, but becomes challenging in a production setting. Query performance using conventional SPARQL constructs is unacceptable to end-users, and finding relevant search results for users queries is an informational retrieval challenge due to the redundant yet slightly variant nature of the Art Historical classification data. We created a virtual Linked Data query engine that integrates a SPARQL API with semantic embeddings using BERT based transformers and RDF2Vec knowledge graph embeddings to provide performant queries in the Dutch Netwerk Digitaal Erfgoed termen netwerk.

🌍Meanwhile in Karlsruhe...
Yesterday, our colleague Hossein Beygi Nasrabadi from the @fizise presented a joint paper at Hashtag#SEconf25 at @KIT_Karlsruhe.

🎓Hossein presented "The NFDIcore Ontology and Related Modular Domain Ontologies", a joint work of himself along with our colleagues @tabea, @sashabruns, Etienne Posthumus, Jörg Waitelonis, @lysander07 Sack and others.
