| 中文摘要:资源描述框架（RDF）是一个元数据模型，是由W3C建立的基础设施，使得Web上的数据机器可读。近年来，语义网的快速发展和RDF的普遍应用，产生了大量的含有时态信息的RDF数据，并涉及到各个方面领域的关键数据。时态RDF数据的一致性能提高时态RDF数据的准确性，时态数据的一致性检测和恢复也有助于提高数据库系统的可靠性和高效性，对于时态信息处理也能提供可靠的保证，也能提高时态信息处理的效率。本文研究了对传统RDF引入时间信息的建模方式，通过添加有效时间的时间标签的方式构建了支持有效时间的时态RDF模型，在此基础上对时态RDF数据存在的不一致性情况进行了分析和研究，并提出了相关的检测和修复的算法。 |

| Abstract:The resource description framework (RDF) is a metadata model, the infrastructure established by the W3C, which makes the data machines on Web readable. In recent years, the rapid development of semantic web and the widespread application of RDF have produced a lot of RDF data containing temporal information and related key data in various fields. Consistent performance of temporal RDF data to improve the accuracy of temporal RDF data, temporal data consistency detection and recovery also helps to improve the reliability and efficiency of the database system, the temporal information processing can also provide a reliable guarantee, also can improve the efficiency of temporal information processing. This paper presents a modeling way of introducing the time information of traditional RDF, temporal RDF models support valid time through constructing the time tag time effective way, inconsistency on the basis of temporal RDF data are analyzed and studied, and put forward the related detection and repair algorithm. |
