Coordinators based on cognitive psychology features and the corresponding KDD process model

Based on cognitive psychology features, we firstly proposed heuristic coordinator and maintenance coordinator, which are exploited to improve the ability of self-cognition of KDD. Then we discussed the design and corresponding algorithms of the two coordinators. To realize self-focusing and real-time maintenance of knowledge base, we also introduced double bases cooperating mechanism, which is the key technology for directional searching and directional mining. Next based on the above two coordinators and double bases cooperating mechanism, we discussed KDD*, and comparative experimental results show that the new process model improve the performance of KDD to a certain extent.
