Extending the coverage of phenotypes in SNOMED CT through post-coordination

Stud Health Technol Inform. 2015;216:795-9.

Abstract

Objectives: To extend the coverage of phenotypes in SNOMED CT through post-coordination.

Methods: We identify frequent modifiers in terms from the Human Phenotype Ontology (HPO), which we associate with templates for post-coordinated expressions in SNOMED CT.

Results: We identified 176 modifiers, created 12 templates, and generated 1,617 post-coordinated expressions.

Conclusions: Through this novel approach, we can increase the current number of mappings by 50%.
