An ontology defines a common vocabulary for researchers who need to share information in a domain. It includes machine-interpretable definitions of basic concepts in the domain and relations among them.Noy & McGuiness

Read more about ontologies in this quick background for health surveillance, or this detailed ontology manual.

The Animal Health Surveillance Ontology (AHSO) is being developed to support health surveillance practice.
– Read more about AHSO here.
– Read more about ORION, an European funded project that promotes one health surveillance data harmonisation. In particular, WP3 is focused on promoting data interoperability, and how ontologies can support the practice of surveillance.

Two Introductory videos have been prepared for those wanting to get involved in Ontology development:
1) Basics of ontologies and knowledge models (WATCH HERE)
2) The use of ontologies in health surveillance (WATCH HERE)

To get more details about the ontology development or get involved:
– The ontology is publicly available in the BioPortal. There you can download or browse the ontology.
– A more narrative description of the ontology, and its individual modules, is available here.
– All ontology classes, and the external catalogues it maps to (such as EFSA and ECDC catalogues) are documented here.
– The ontology is also on GitHub, where you can see and contribute to codes, and review or submit an issue.
– If you are or want to be part of the development team, you can view all shared documentation files in this shared drive.
– We have regular webinars to progress in the ontology development. You can see summarized documentation, and full recordings of the webinars here,
