Improving the exchange of medical information through applied ontologies

As part of the Open Biological and Biomedical Ontology (OBO) Foundry, the GRIIS is joining forces with an international community that develops compatible ontologies.

An ontology is a rigorous representation of a domain of reality (e.g. the medical field). It uses language that computers understand. This allows computers to reason in an automated way. By means of computer science, we can automatically test the logical coherence of an ontology or infer new knowledge.

At the GRIIS, we develop ontologies in the biomedical field, such as an ontology of drug prescriptions or an ontology of cardiovascular diseases. These ontologies are subsequently applied in health informatics.

Ontologies can assist the linkage of health data that is diverse and heterogeneous (e.g. clinic and hospital data). With ontologies, computer systems can communicate with each other, even though they may be constructed differently.

Ontologies

Prescription of Drugs Ontology (PDRO)

PDRO is a realist ontology that aims to represent the domain of drug prescriptions. PDRO’s central focus is the structure of a drug prescription.

The PDRO ontology is the topic of a scientific article published in the journal Applied Ontology.

Cardiovascular Disease Ontology (CVDO)

The CVDO ontology differentiates between cardiovascular diseases, underlying disorders and associated pathological processes.

It is based on the disease model proposed by the Ontology for General Medical Science (OGMS).

Clinical Laboratory Test Document Ontology (LABO)

The LABO ontology represents documents that prescribe laboratory tests and that provide their results.

It is coordinated with OBO Foundry ontologies like the Information Artifact Ontology (IAO) and the Ontology for Biomedical Investigations (OBI).
