| Abstract: | 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. |
