While keyword based queries of databases such as Pubmed are frequently of great utility, the ability to use regular expressions in place of a keyword can often improve the results output by such databases. Regular expressions can allow for the identification of element types that cannot be readily specified by a single keyword and can allow for different words with similar character sequences to be distinguished.
A Perl based utility was developed to allow the use of regular expressions in Pubmed searches, thereby improving the accuracy of the searches.
This utility was then utilized to create a comprehensive listing of all DFN deafness mutations discussed in Pubmed records containing the keywords "human ear".
虽然诸如PubMed等数据库基于关键词的查询通常非常有用,但使用正则表达式代替关键词往往可以改善此类数据库输出的结果。正则表达式能够识别单个关键词难以明确指定的元素类型,还能区分具有相似字符序列的不同单词。
开发了一种基于Perl的实用工具,以便在PubMed搜索中使用正则表达式,从而提高搜索的准确性。
然后利用此实用工具创建了一份全面的清单,列出了在包含关键词“人耳”的PubMed记录中讨论的所有DFN耳聋突变。
