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.

Who's working the most higher-order #classification systems of things in the world? Systematics in biology work on classifying all living things. Every field has their own classification systems. Is there a field that integrates those classification systems to create a "taxonomy of everything"? When I search for that concept I'm pointed towards people working on #SemanticWeb - I'm curious if there are any good sources out there to read up on, especially actual attempts/examples! #taxonomy

🔗 SHACL-SKOS Based Knowledge Representation of Material Safety Data Sheet (SDS) for the Pharmaceutical Industry

arxiv.org/abs/2502.07944

arXiv logo
arXiv.orgSHACL-SKOS Based Knowledge Representation of Material Safety Data Sheet (SDS) for the Pharmaceutical IndustryWe report the development of a knowledge representation and reasoning (KRR) system built on hybrid SHACL-SKOS ontologies for globally harmonized system (GHS) material Safety Data Sheets (SDS) to enhance chemical safety communication and regulatory compliance. SDS are comprehensive documents containing safety and handling information for chemical substances. Thus, they are an essential part of workplace safety and risk management. However, the vast number of Safety Data Sheets from multiple organizations, manufacturers, and suppliers that produce and distribute chemicals makes it challenging to centralize and access SDS documents through a single repository. To accomplish the underlying issues of data exchange related to chemical shipping and handling, we construct SDS related controlled vocabulary and conditions validated by SHACL, and knowledge systems of similar domains linked via SKOS. The resulting hybrid ontologies aim to provide standardized yet adaptable representations of SDS information, facilitating better data sharing, retrieval, and integration across various platforms. This paper outlines our SHACL-SKOS system architectural design and showcases our implementation for an industrial application streamlining the generation of a composite shipping cover sheet.

Frank van Harmelen at the ISWS 2023 presenting his keynote. The slide shown in the background has the heading "This is not a kn owledge graph". It says that the small graph depicted on it is merely a data graph as it doesn't allow for any inferencing.
