An analysis of SAPHIRE, an experimental information retrieval system featuring automated indexing and natural language retrieval, was performed on MEDLINE references using data previously generated for a MEDLINE evaluation. Compared with searches performed by novice and expert physicians using MEDLINE, SAPHIRE achieved comparable recall and precision. While its combined recall and precision performance did not equal the level of librarians, SAPHIRE did achieve a significantly higher level of absolute recall. SAPHIRE has other potential advantages over existing MEDLINE systems. Its natural language interface does not require knowledge of MeSH, and it provides relevance ranking of retrieved references.
对一个具有自动索引和自然语言检索功能的实验性信息检索系统——蓝宝石（SAPHIRE）进行了分析，使用先前为医学文献数据库（MEDLINE）评估生成的数据，对MEDLINE参考文献进行了分析。与新手和专家医生使用MEDLINE进行的检索相比，蓝宝石系统（SAPHIRE）实现了相当的召回率和精确率。虽然其综合召回率和精确率性能不及图书馆员的水平，但蓝宝石系统（SAPHIRE）确实实现了显著更高的绝对召回率。与现有的MEDLINE系统相比，蓝宝石系统（SAPHIRE）还有其他潜在优势。其自然语言界面不需要医学主题词表（MeSH）知识，并且它提供检索到的参考文献的相关性排名。
