Research on Data Mining Preprocessing Technology Based on Attribute Extension
Zhang Chun-shen · Computer Technology and Development · 2014
Nowadays the data mining technology is basically based on the information of the original database. Data preprocessing technology must maintain the information of the original database unchanged,just for simple data standardization,data level,abnormal points found,missing data repair work,data discrete and other basic data pretreatment,not radically expanded the information in the original database. Meanwhile,for the sake of secrecy,the privacy preserving of data mining technology deals with the sensitive data in the original database,and hides some basic information,further weakening the information content in the original database. The data mining preprocessing technology based on the attribute extension starts from the original database,expands the information implicated in basic database by extending the attribute from the original database perspective,so that data mining can produce more deeply hidden rules.
