摘　　要：目的:将随机对照试验评价的基本理论和知识整合为计算机可识别的语义模型、属性和元数据,为语义网计算机推理提供知识本体.方法:知识本体的建立以国际上公认的随机对照试验评价规范为依据,采用本体编辑工具Protégé构建语义模型的层级结构,定义类、属性及其关系和其他元数据的规范描述.结果:构建了包含一般信息、分类与分级信息和具体评价项目的语义模型,创建了51个语义属性和元数据,13个随机对照研究的评价实例.结论:构建计算机可识别和处理的随机对照试验评价本体,是网络医学文献信息逻辑推理操作的基础,也为医学研究过程提供了随机对照试验文献质量评价的形式化表达和结果推论的参考.AIM：Applying fundamental appraisal theory and basic knowledge of randomized controlled trial to develop a computer readable knowledge model and create template slots and metadata,to present ontology knowledge for critical appraisal.METHODS：The ontology was extracted from recognized international appraisal theory.The knowledge-edit software Protégé was used to construct knowledge class hierarchy,define the properties of classes-slots,the facets of the slots and metadata.RESULTS：A computer readable knowledge model was developed which included basic elements,appraisal items and related principles,contained 51 slots and related metadata.Thirty instances of published randomized controlled trials were created.CONCLUSION：Computer readable knowledge ontology is a base for automatic logical operation on web information.The electronic expression of appraisalknowledge model of randomized controlled trial will help medical researchers to create instances and their own self-description web documents regardless the complicated web ontology language.
