本文研究了CNKI的同句和同段检索功能在查新中文文献检索中的应用。CNKI同句和同段检索是全文检索,但要求检索词在同句或同段中出现,避免了采用“全文”字段检索结果篇数过多且相关性不高的弊端,也可减少通过“主题”字段检索造成的漏检。同句和同段检索的“结果中检索”功能可对检索结果进行二次检索,也可精确限制两个检索词在同段中的相对位置。利用同句和同段检索功能可提高查准率,减少文献判读时间。
This paper studies the application of the same sentence and retrieval function of CNKI in searching new Chinese documents. CNKI with the same sentence and the same paragraph search is full-text search, but requires the search terms appear in the same sentence or the same paragraph, to avoid the “full text ” field search results too many articles and the relevance of the drawbacks can also reduce Missing seized by “Subject” field retrieval. The same sentence and the same paragraph search “search results ” function can search the results of secondary search, but also can accurately limit the two search terms in the same relative position. Use the same sentence and the same paragraph search function can improve the accuracy rate, reduce the document interpretation time.
