使用之前为MEDLINE评估生成的数据，对MEDLINE参考文献进行了分析，Sapire是一个以自动标引和自然语言检索为特色的实验性信息检索系统。与新手和专业医生使用MEDLINE进行的搜索相比，Sapire获得了类似的召回率和精确度。虽然它的综合召回率和精确度表现没有达到图书馆员的水平，但Sphire的绝对召回率确实要高得多。与现有的MEDLINE系统相比，Sapire还有其他潜在的优势。它的自然语言界面不需要网格知识，并提供检索到的参考文献的相关性排名。
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.
