摘要
为提高KDD自认知能力,首次提出了基于认知心理特征的启发协调器和维护协调器.讨论了其设计及相应的实现算法.为实现知识库的自聚焦和实时维护,引入了双库协同机制用于方向搜索和方向挖掘.建立了相应的过程模型KDD*,实验结果显示此过程模型改善了KDD的性能.
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.
