语义网环境下PROV数据溯源技术应用研究

Data Provenance on Semantic Web Based on PROV

摘要: 如何在开放环境下建立通用的，可以在异构系统之间交换、共享溯源信息的规则，是目前数据溯源技术的研究热点。本文引入了W3C提出的PROV数据溯源机制，重点探讨了在语义网环境下如何建立数据溯源核心概念模型以及如何用本体语言对溯源信息进行语义描述，构建了数据溯源实例进行验证，并展望了开放环境下溯源技术的研究发展方向。

Abstract: It is a research hotspot about how to establish a general rule of exchanging and sharing provenance information in heterogeneous systems. In this paper, we introduced the concept and usage of PROV, and put forward an idea about how to set up data provenance conceptual model and describe provenance information in ontology language. Finally, we established a scenario to test and verify the practical applicability and discussed the future direction in this field.
