目的：开发一个基于知识的表示为临床信息的受控术语，以促进创建，维护和使用的Terminations.Design：医学实体字典（MED）是一个语义网络，租赁的统一医学语言系统（UMLS），与有向无环图来表示多个层次结构。从四个医院系统（实验室，心电图，医疗记录编码和药房）的术语被添加为网络中的节点。有关术语作为语义链接添加的额外知识，用于协助不同的术语的集成，协调和自动分类。结果：MED包含32,767个术语，并在积极的临床使用。自动分类成功地应用于实验室标本，实验室检查和药物的术语。该方法的一个好处是将药物自动纳入药房系统中不存在的多个药理学和过敏性类别。另一个好处是减少了90%的维护工作。结论：MED是术语和知识的混合体。它提供了域覆盖、同义关系、视图的一致性、明确的关系和多重分类，同时防止冗余、歧义（同音异义）和错误分类。
Objective: Develop a knowledge-based representation for a controlled terminology of clinical information to facilitate creation, maintenance, and use of the terminology.Design: The Medical Entities Dictionary (MED) is a semantic network, leased on the Unified Medical Language System (UMLS), with a directed acyclic graph to represent multiple hierarchies. Terms from four hospital systems (laboratory, electrocardiography, medical records coding, and pharmacy) were added as nodes in the network. Additional knowledge about terms added as semantic links, was used to assist in integration, harmonization, and automated classification of disparate terminologies.Results: The MED contains 32,767 terms and is in active clinical use. Automated classification was successfully applied to terms for laboratory specimens, laboratory tests, and medications. One benefit of the approach has been the automated inclusion of medications into multiple pharmacologic and allergenic classes that were not present in the pharmacy system. Another benefit has been the reduction of maintenance efforts by 90%.Conclusion: The MED is a hybrid of terminology and knowledge. It provides domain coverage, synonymy, consistency of views, explicit relationships,and multiple classification while preventing redundancy, ambiguity (homonymy) and misclassification.
