Tools, Resources, and Ontologies

We build tools, resources, and ontologies that improve trustworthiness of intelligent systems — and methods for evaluating them. This page tracks the resources we've published.

Resources

HOnEst

A human-centric approach to evaluating ontology quality, so that ontologies built into AI systems support factually correct, unbiased behaviour. Funded by the FWF Austrian Science Fund.

ontology evaluation

BEAM Notation

A visual notation for annotating machine learning pipelines, with a core ontology, a risk-focused extension, a draw.io library and a worked tutorial covering PyTorch workflows.

ML annotation

SWeMLS Ontology

An ontology for describing machine learning systems on the semantic web — their components, data and provenance — so ML pipelines can be represented as knowledge graphs.

ML system ontology

KG-based Data Augmentation for ML Prediction

Architecture diagrams accompanying our paper on semantic-based data augmentation, comparing baseline, embedding- and clustering-based strategies for improving ML predictions.

supplementary material

SENSE Ontology

An ontology for explainability in cyber-physical and sensor systems, extending the W3C SOSA/SSN vocabularies. Developed as part of the FFG-funded SENSE project.

explainability

SoCK Ontology

An ontology for representing and synthesising causal knowledge, connecting expert domain knowledge with data-driven causal discovery in cyber-physical systems.

causal knowledge

OCEDO

An ontology for object-centric event data, plus a translator that converts XES event logs into OCEDO-compliant RDF. Developed with the University of Rome and Utrecht University.

event data ontology

Football CDF Ontology

A common data format ontology for representing football match and event data, published as JSON-LD, RDF/XML, N-Triples and Turtle with a WebVOWL visualisation.
