Semantic EHR Ontology
The Semantic EHR Ontology represents the clinical trail domain and described as a domain level ontology
Objectives Enable sharing and linking of healthcare and clinical
terminologies Sharing consistent and unambiguous knowledge for
decision making in medical and clinical research domains (Sub)Domains
Partially covers Breast Cancer, Diabetic, Adverse Event (AE), Concomitant Medication (CE), Neurology, Genetics, Psychiatric Disorder, and Respiratory
Local institute (domain)-specific variables

Evaluating Semantic EHR Ontology
The questionnaires were answered by clinical experts from various sub-domain of Healthcare and Life Sciences
Clinical experts suggested conceptualisation fixes (i.e., hierarchy and/or names of classes and properties) that suit their local requirements
Clinical experts agree that SEHR ontology covers the needs of the clinical trial domain
We are doing a final (fourth) round of evaluation
