CISMeF is a French quality-controlled health gateway that uses the MeSH thesaurus. We introduced two new concepts, metaterms (medical specialty which has semantic links with one or more MeSH terms, subheadings and resource types) and resource types.
Evaluate precision and recall of metaterms.
We created 16 pairs of queries. Each pair concerned the same topic, but one used metaterms and one MeSH terms. To assess precision, each document retrieved by the query was classified as irrelevant, partly relevant or fully relevant.
The 16 queries yielded 943 documents for metaterm queries and 139 for MeSH term queries. The recall of MeSH term queries was 0.44 (compared to 1 for metaterm queries) and the precision were identical for MeSH term and metaterm queries.
Metaconcept such as CISMeF metaterms allows a better recall with a similar precision that MeSH terms in a quality controlled health gateway.
CISMeF是一个使用医学主题词表（MeSH）的法国质量控制健康网关。我们引入了两个新概念，元术语（与一个或多个MeSH术语、副标题和资源类型有语义联系的医学专业）和资源类型。
评估元术语的精确率和召回率。
我们创建了16对查询。每对查询涉及相同主题，但一个使用元术语，另一个使用MeSH术语。为了评估精确率，将查询检索到的每个文档分类为不相关、部分相关或完全相关。
16个查询为元术语查询产生了943篇文档，为MeSH术语查询产生了139篇文档。MeSH术语查询的召回率为0.44（元术语查询为1），MeSH术语查询和元术语查询的精确率相同。
像CISMeF元术语这样的元概念在质量控制的健康网关中能够以与MeSH术语相似的精确率实现更好的召回率。
