| 摘 要： | 目的 :通过比较一体化医学语言系统 (下文简称UMLS)对搜索引擎检索结果的影响 ,探讨UMLS能否提高搜索引擎检索效率。方法 :选取 3组不同类型的医学提问词 ,设计 3个测试 ,比较UMLS对医学和通用搜索引擎及文献检索软件检出记录数的影响。结果 :经UMLS转换提问词后 ,3个测试中 3组不同类型提问词检出记录数均有增加 ,经统计学处理有显著差异。结论 :UMLS能提高医学和通用搜索引擎及文献检索软件的检索效率。但UMLS在搜索引擎中的应用尚处于起步阶段 ,有待进一步的研究与开发

| Abstract: | Objective:Explore the difference between search engines supported by Unified Medical Language System(Abbreviated as UMLS in the following)and those not in searching medical information;evaluate the effect of UMLS upon the search efficiency of search engine.Method:Selected three group of medical search terms that of different type;designed three tests to reveal the effect of UMLS upon the output of medical,general,and documents search engine.Result:When transformed by UMLS,the output of the three groups of search terms increased in varied degree,and the difference is evident by statistical disposal.Conclusion:UMLS can promote the search performance of medical,general,and documents search engine.But the application of UMLS to search engine is still in primary stage,waiting for further study and development. |
