医学领域的决策支持系统必须由医学专家自己轻松修改。作者设计了一种知识获取工具，以方便领域专家创建和维护知识库以及其他机构的共享和重用。统一医学语言系统（UMLS）包含领域实体并构成关系存储库，专家通过特定的浏览器从中构建显式领域本体。然后，指导专家根据预先建立的领域本体和条件动作规则模板创建知识库，这些模板非常适合多种临床决策过程。最终生成相应的医学逻辑模块。这种知识获取工具在输血决策支持系统构建中的应用证明了这种实用方法对于设计基于规则的临床系统的价值，该系统依赖于医院信息系统中嵌入的高度进步的知识。
Decision support systems in the medical field have to be easily modified by medical experts themselves. The authors have designed a knowledge acquisition tool to facilitate the creation and maintenance of a knowledge base by the domain expert and its sharing and reuse by other institutions. The Unified Medical Language System (UMLS) contains the domain entities and constitutes the relations repository from which the expert builds, through a specific browser, the explicit domain ontology. The expert is then guided in creating the knowledge base according to the pre-established domain ontology and condition-action rule templates that are well adapted to several clinical decision-making processes. Corresponding medical logic modules are eventually generated. The application of this knowledge acquisition tool to the construction of a decision support system in blood transfusion demonstrates the value of such a pragmatic methodology for the design of rule-based clinical systems that rely on the highly progressive knowledge embedded in hospital information systems.
