Recent Research Progress on Extension Data Mining Methods

“…It theoretically applies the extension set theory and extension logic [8] in data mining, corresponds the database and data warehouse to the extension set's universe of discourse, and corresponds the data to the basic-elements, consequently combines the extension set theory with data mining, to form the basic theory [9][10][11] to mine the "extension knowledge". In terms of methodology, it combines the formalization system with basic-elements as logical cells with the database and data warehouse, to form the knowledge representation suitable for data "transformation", and uses the extension reasoning and dependent function as tools to establish a set of extension data mining methods that are suitable for extension knowledge mining, and further develops the experimental software [12][13][14] of obtaining "extension knowledge".…”
