摘要
为了改进当前数字资源长期保存技术存在的缺点,有效构建数字资源长期保存系统,在分析当前基于本体的数字资源长期保存系统存在的如本体集成度差、不能提供本体进化时的时间语义信息、忽视一致性维护和更改传播等缺点的基础上,介绍了Heraclitus II双时态本体模型及其应用特点,主要基于Heraclitus II本体技术构建了数字资源长期保存系统。具体包括本体构建和集成、协同本体管理、本体演化需求、本体演化过程等组件,详细分析了各个组件的功能。研究结果表明,应用Heraclitus II双时态本体技术能有效构建数字资源长期保存系统,实现数字资源长期保存的要求。研究结果对新媒体环境下数字资源长期保存系统的构建有一定参考作用。
In order to improve the shortcomings of current long-term preservation technology of digital resources and effectively construct long-term preservation system of digital resources, based on the analysis of the problems such as poor ontology integration, not providing time semantic information of ontology evolution, neglecting consistency maintenance and propagating changes of long-term preservation system of digital resources based on ontology, the Heraclitus lI bitemporal ontology model and its application characteristics are intro- duced. It mainly constructs long term preservation system of digital resources based on Heraclitus II ontology technology in this paper. The system includes the ontology construction and integration, ontology collaborative management, ontology evolution requirements, ontology evolution process components, and the function of each component is analyzed in detail. The research indicates that long-term preservation system of digital resources can be effectively constructed based on Heraclitus II bitemporal ontology technology, achieving requirements of long-term preservation system of digital resources,which gives a certain reference to construct long-term preservation system of digital resources under the environment of new media.
