一种本体演化波及效应分析方法

本文提出了一种本体图模型,建立了本体邻接矩阵和可达矩阵,凭借矩阵变换与运算对本体演化中的波及效应进行了深入的分析和量化界定;文中阐述了对演化中的本体变化操作所引起的各种波及效应;给出了本体元素对本体结构的贡献大小、本体内聚度及本体演化中元素受影响程度的计算方法,并且分析了依赖未知情况下的本体演化的波及效应问题,提出了一种支持本体演化的服务模型,从而为本体演化的管理、控制、利用和评价提供了可靠的依据,为本体演化的计算机自动处理奠定了基础.

A Ripple-Effect Analysis Method for Ontology Evolution

An ontology graph model,which creates ontology adjacency matrix and ontology reachability matrix, is described. Depending on matrix shift and calculation, ripple-effect of ontology evolution can be analyzed and its quantity can be ascertained. Every ripple-effect caused by ontology change operation is described. At the same time, approaches for calculating ontology element contribution, ontology cohesions and effect degree applied to every ontology element during ontology evolution, are provided. Ripple-effect analysis for dependency-unknown ontology evolution is discussed, and a server model for ontology evolution is also provided. All are credible foundation for management, control, usage and evaluation of ontology evolution, and are foundation for ontology evolution automation calculation in computer.
