目的：这项研究有两个目标：首先，识别和描述在统一医学语言系统（UMLS）元词库（2007 AB）中找不到的消费者健康术语;其次，描述在构建消费者健康词汇表的过程中创建新概念的过程。未映射的消费者健康概念如何与现有的UMLS概念相关联？这些新概念在专业医学话语中的地位是什么？设计图：消费者健康词汇是从开放获取合作实验室消费者健康词汇（OAC CHV）建设过程中获得的两个大型语料库中提取的。无法映射到现有的UMLS概念，通过机器和手动方法促使创建新的概念，然后归因于语义类型，现有的UMLS概念，并根据指定的criteris.Results编码：这种方法确定了64个未映射的概念，其中17个被标记为唯一的“奠定”，不可行的专业健康术语。其余的条款构成潜在的候选人列入专业词汇，或可以通过后协调现有的UMLS条款。新的和现有的概念之间的关系不同，这取决于语料库，它们是extracted.Conclusion：非映射的概念构成了一小部分的消费者健康方面，但一个比例，这是可能会影响消费者健康词汇建设的过程。我们已经确定了一种识别此类概念的新方法。
Objective: This study has two objectives: first, to identify and characterize consumer health terms not found in the Unified Medical Language System (UMLS) Metathesaurus (2007 AB); second, to describe the procedure for creating new concepts in the process of building a consumer health vocabulary. How do the unmapped consumer health concepts relate to the existing UMLS concepts? What is the place of these new concepts in professional medical discourse?Design: The consumer health terms were extracted from two large corpora derived in the process of Open Access Collaboratory Consumer Health Vocabulary (OAC CHV) building. Terms that could not be mapped to existing UMLS concepts via machine and manual methods prompted creation of new concepts, which were then ascribed semantic types, related to existing UMLS concepts, and coded according to specified criteria.Results: This approach identified 64 unmapped concepts, 17 of which were labeled as uniquely "lay" and not feasible for inclusion in professional health terminologies. The remaining terms constituted potential candidates for inclusion in professional vocabularies, or could be constructed by post-coordinating existing UMLS terms. The relationship between new and existing concepts differed depending on the corpora from which they were extracted.Conclusion: Non-mapping concepts constitute a small proportion of consumer health terms, but a proportion that is likely to affect the process of consumer health vocabulary building. We have identified a novel approach for identifying such concepts.
