摘要
【目的】揭示知识库与数据库之间的对应关系,并以此为基础将数据库、知识库统一在知识获取的过程中,提高知识库获取知识的速度、精度和认知自主性。【方法】针对面向知识服务的双库协同知识库框架,研究框架结构的启发型协调器与中断型协调器各自算法及协同合作的作用。【结果】提出双库协同知识库框架结构模型,研究知识库与数据库各自结构的关联及映射关系,从而实现双库协同的架构,并给出协同工作的过程模型。【局限】双库协同的各类数据源均考虑在同构的条件下,而在大数据环境下各类异构、多维数据未能全面涉及。【结论】为知识服务提供"全"且"准"的知识,给出的框架结构在实现减小搜索空间、提高挖掘效率方面起到重要的支撑作用。
[Objective] The paper reveals the relationship between the knowledge base and database, and the double-base cooperates in the process of knowledge acquisition, to improve the speed, accuracy and cognitive autonomy. [Methods] The knowledge service-oriented model of knowledge base frame structure research is based on double-base cooperating. The research of this model focuses on the heuristic coordinator and interruptive coordinator, which their algorithms and collaborative effects are given for high efficiency knowledge service. [Results] The model of knowledge base frame structure on double-base cooperating is presented. In this model, the relation between knowledge base and database and their mapping relationship are given. Finally, double-base cooperating is achieved, and the process model is described. [Limitations] The data sources in double-base cooperating are considered as homogeneity, but other heterogeneous data sources and multidimensional data are not fully involved. [Conclusions] The knowledge base frame structure plays a supporting role, which reduces the search space and improves mining efficiency.
