SAPHIRE is a concept-based approach to information retrieval in the biomedical domain. Indexing and retrieval are based on a concept-matching algorithm that processes free text to identify concepts and map them to their canonical form. This process requires a large vocabulary containing a breadth of medical concepts and a diversity of synonym forms, which is provided by the Meta-1 vocabulary from the Unified Medical Language System Project of the National Library of Medicine. This paper describes the use of Meta-1 in SAPHIRE and an evaluation of both entities in the context of an information retrieval study.
蓝宝石（SAPHIRE）是生物医学领域中一种基于概念的信息检索方法。索引和检索基于一种概念匹配算法，该算法处理自由文本以识别概念并将它们映射到其规范形式。这个过程需要一个包含广泛医学概念和各种同义词形式的大词汇表，这由美国国立医学图书馆统一医学语言系统项目的元1词汇表提供。本文描述了元1在蓝宝石中的使用以及在信息检索研究背景下对这两个实体的评估。
