## Description

## Ontology Info

| Field | Value |
|-------|-------|
| Acronyme | SCTO |
| Description | The Systematized Nomenclature of Medicine Clinical Term Ontology (SCTO) attempts to create a basic OWL 2 ontology for SNOMED CT terminology. The ontology is built based on the Ontology of General Medical Science (OGMS). This ontology implements the SNOMED CT concept model by adding the appropriate axioms to its top-level concepts. The resulting ontology can prevent redundancies and inconsistencies in this large terminology. Moreover, the terminology maintenance can become more accurate. Finally, SNOMED CT can be used in a healthcare environment to create more complex post-coordinated expressions and constraints in a more accurate manner. |
