基于文本文件的可拓数据挖掘方法研究
|
摘要
本文介绍了可拓学理论与可拓数据挖掘技术的基本概念与基本方法,并将可拓数据挖掘技术用于"5·12"汶川地震空间电离层电场文本数据文件的处理。利用自行开发的数据挖掘软件进行数据分类,在震前10天数据中,得到了2个关联度异常文件,并计算了挖掘知识的支持度与可信度。
This paper presents a basic concept and method of the extenics theory and extenics data mining technology, and moves the technology to the data processing of in space ionosphere electric fields of "5.12" Wenchuan earthquake.With the self-developed data mining software,a data classification shows two exceptional correlation files among the data 10 days before the earthquake,and the support degree and credibility of the data mining knowledge are calculated as well.
