面向知识发现的数据连续性保障机制研究

Knowledge Discovery Oriented Data Continuity Protection Mechanism

文章构建面向知识发现的数据连续性保障机制,保障知识发现过程中数据的可用、可信与可控,为数据连续性研究的深入开展提供理论支撑。以数据连续性的内涵为研究起点,面向知识发现的数据连续性保障机制的横向维度包含数据准备、数据分析、结果展示,纵向维度包含关联数据层级、数据空间层级、数据溯源层级,并对各层级功能模块进行详细设计。从主题相关性和主体相关性融合角度完善数据连续性的管理与保障,并将数据溯源技术贯穿于知识发现全流程。

The data continuity security mechanism for knowledge discovery was constructed to ensure the availability, credibility and controllability of data. The research provided theoretical support for the further research of data continu- ity. Firstly, the connotation of data continuity was expounded. Then, the horizontal dimension of data continuity securi- ty mechanism included data preparation, data analysis and result display. The vertical dimension included linked data level, dataspace level and data provenance level, and the function modules of each level were designed in detail. The mechanism improved the data continuity management from the perspective of subject-related and principal-related fu- sion, and the data provenance technology ran through the whole process of knowledge discovery.
