Digital Enterprise Research Institute Enabling Networked Knowledge 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 6/7
