| Abstract: | Based on cognitive psychology features,heuristic coordinator and maintenance coordinator were proposed for the first time to improve the ability of self-cognition of KDD.The design and the corresponding algorithms of the two coordinators were discussed then.To realize self-focusing and real-time maintenance of knowledge bases,the double base cooperating mechanism was introduced,which was the key technology for directional searching and directional mining.Based on the two coordinators and double base cooperating mechanism,process model KDD* was discussed,and the comparative experimental results show that the new process model improves the performance of KDD to a certain extent. |
