Terminology

Ontology bindings

The term_binding section stores bindings between a particular term

within the archetype and an equivalent concept in an ontology

Equivalence relationsBlood Pressure Arquetype Physiology ontology

By linking the classes through a Necesary & Suficient condition we allow a reasoner to check data correctness and data coherence while preserves the ontology modularity during its exploitation.

Enriched archetypes

The Systolic pressure concept, defined in the archetype, is enriched

with properties and attributes from the

equivalent class within the Physiology

ontology

Conclusions The Archetype Model should be improved in order to

prevent concept overlapping. Existing archetypes cover several concepts of the OGMS

ontology, although some ambiguities have been revealed. Three mapping approaches were presented for the

integration of the OGMS ontology : AM – OGMS, direct mapping.

Definition of the OGMS as a part of the Reference Model

Creation of a Disease layer between the RM and the AM

The translation from ADL to OWL offers several advantages for reusability, coherence checks and navigability between archetypes and clinical ontologies.
