The development of a framework of One Health Surveillance (OHS) faces varied data interoperability challenges – among institutions, across health surveillance sectors, and among countries. Interoperability is used here to mean “the ability of different information technology systems and software applications to communicate, exchange data, and use the information that has been exchanged”. Semantic interoperability, in particular, is concerned with ensuring the integrity and meaning of the data across systems. Semantic interoperability is particularly important in One Health in order to allow data reuse across sectors, and even reuse of data for research and knowledge discovery.
HSO aims to support data interoperability in One-health Surveillance.
Several terminology catalogues already exist in health and epidemiology. Ontologies can incorporate these existing resources and re-use all their knowledge. But we move beyond the listing of concepts and include also “relationships” between concepts (semantics), creating a knowledge model for health surveillance. A machine-interpretable version of the domain knowledge offers several advantages, in particular:
– Use of automated reasoners to make inferences and detect errors in the data.
– Flexibility to accommodate to knowledge growth and updates.
– Reuse. Ontologies are meant to model specific pieces of knowledge, in a way that allows linking to complementary pieces. As epidemiology is highly multi-disciplinary, the use of ontologies allows us to piece together expertise from many different domains.
– Interoperability. Terminologies allow humans to understand each other and agree on what things mean. Ontologies allow software to talk to each other.

Project management and structure
This project is managed by the Swedish National Veterinary Institute. This project started as the Animal Health Surveillance Ontology, funded by the Swedish Innovation Agency – Vinnova. It has evolved into an ontological framework composed of HSO, as well as an ontology focus on animal health data sources (visit AHO).
Current core members:
– Fernanda Dórea, project leader: National Veterinary Institute, Sweden
– Crawford Revie: University of Prince Edward Island, Canada
