Applying description logics extended with meta-modelling to SNOMED-CT

Abstract:

SNOMED-CT is a clinical and medical ontology that covers a wide range of concepts in the health domain. It is mostly used as a standard vocabulary to be referenced in electronic health records of patients. The SNOMED-CT ontology has been formalized with a description logic, the Web Ontology language OWL 2 profile OWL-EL. To integrate electronic health records to SNOMEDCT in an OWL-EL ontology, references to SNOMED-CT concepts in these records are modelled as instances of the referenced concepts. In this paper, the ontological model of this integration is analyzed. As our main contribution, we propose to give solution to some problems of this integration by defining a metamodel layer of SNOMED-CT with its concepts represented also as individuals, using an approach of description logics extended with meta-modelling.
