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。
This paper constructs a data continuity guarantee mechanism for knowledge discovery, which guarantees the availability, credibility and controllability of data in the process of knowledge discovery and provides theoretical support for the further development of data continuity research. Taking the connotation of data continuity as the research starting point, the horizontal dimension of data continuity assurance mechanism for knowledge discovery includes data preparation, data analysis and result display. The vertical dimension includes the associated data level, data space level and data traceability level, Hierarchical functional modules for detailed design. The management and guarantee of data continuity are improved from the perspective of the combination of subject relevance and subject relevance, and the data traceability technology runs through the whole process of knowledge discovery.
