Abstract
Objective: This study aims to develop the web-interface creator, which automatically changes the Case Report Form(CRF) web page when the protocol developer in any clinical study revises the ontology of CRF. Methods: This study established the conceptual model of CRF on oriental and western medicine, and developed ontologies. A program was developed to produce online-based a input form through the parser that generates automatically HTML script from OWL. Results: The CRF applied in this study is a draft through consensus of experts for stroke research at the Korea Institute of Oriental Medicine. The ontology of CRF consisted of Label, ControlType and Value classes and hasControl, hasValue and hasSymptoms properties. The Label is the class of question items groups, so it could have CRF questionnaire instances. The ControlType is the class that expresses controls such as checkbox, text, etc in the HTML script. The Value class represents selections for each items. Finally, the HTML script was created by XSL transformation from the OWL script. Conclusion: Online-based automatic interface creation, which enables immediate coping with the continuous change in the medical knowledge system, assures reduced time requirement.
