| 摘 要： | 采用面向主题词/副主题词的PubMed数据挖掘软件对从PubMed下载的MEDLINE格式文献的主题词字段进行字符串的查询统计,以达到数据挖掘的目的.该软件主要有三个方面的功能:分析主题词与副主题词的频次、频率以及主题词与副主题词的组配关系,可以进一步对下载的记录进行主题词/副主题词之间的组配检索;分析关于某类事物(如药物或治疗过程等)在不同时间段的分布情况;通过对一组相同类型的不同事物间(如多个药物或治疗过程等)发表文献的比较,得到这些事物的相似度.

| Abstract: | The subject headings and subheadings oriented PubMed data-mining software can be used to search and calculate the strings of subject heading segment in MEDLINE format downloaded from PubMed to achieve data mining. It has three functions: 1. to analyze the frequency, and co-ordinate relation rate of Medical Subject Headings (MeSH) in for further co-ordinate searching the downloaded records combined with MeSH and subheadings; 2. to analyze the distribution of factors such as drugs and their treatment process at different times; 3. to compare literature of a series of different factors in a same type (e.g. several drugs and their treatment process) to achieve their similarity. |
