The Research On Knowledge Discovery In Multi_databases Based On ECL

It is a hotspot that Knowledge Discovery in Databases(KDD) in the databases study currently, while concept lattice is a powerful mathematical tool that describes data and processes knowledge discovery.The thesis mainly focuses on the research of data mining based on extended concept lattice, the context is involved with the complete generation of ECL as well as the knowledge pick_up and combination based on it.In generation of ECL, according to the internal relation between RRECL and ECL , thie thesis come up with a new ideal ,which is to use RRECL and the generating intension group to construct ECL.On the aspect of knowledge pick_up based on ECL , the thesis points out the possibility of using ECL to carry out the process of multi_database knowledge discovery; And further, brings out the theories of the multi_database knowledge combination based on ECL ;put forward a method of using ECL, RRECL on knowledge check, and applies it to the knowledge maintenance.Besides, the thesis also introduces MDKDD, a tool for knowledge discovery in multi_database, explains its relation views, algorithm as well as related data.
