基于MeSH主题词的口腔医学专业文献检索策略

Retrieval strategy for dentistry literatures based on medical subject headings

目的 探索一种基于MeSH主题词的较完善的检索策略,以实现对口腔医学专业文献检索的需求.方法 对PUBMED主题词树状结构表进行全面分析,结合口腔医学常用词汇的验证补充,寻找到与口腔医学密切相关的6个主题词,从而获得较全面的口腔医学文献检索策略.结果 应用该策略检索2006-2008年的口腔医学相关文献,共获得102 500篇.结论 该检索策略有助于提高口腔医学临床、科研工作者的文献检索效率,为口腔医学文献追踪提供有效的方法.

Objective To investigate a retrieval strategy for dentistry literature based on medical subject headings （MeSH）. Methods We analysed the MeSH Tree Structures of PubMed in 2009 and combined it with the core glossary of dentistry to find out highly frequent dental words in MeSH. Then 6 words were singled out from the whole MeSh Tree to apply for a retrieval strategy for dentistry literatures. Results 102,500 pieces of dentistry literature were obtained from the year 2006 to 2008. Conclusions This research strategy can improve the efficiency of literature search in dentistry field for clinical or laboratory researches.
