关联数据中owl:sameAs网络分析

Analyzing owl:sameAs Network in Linked Data

【目的】调研owl:same As连接在真实数据网络中的配置和应用情况。【方法】从BTC 2014数据集中抽取部分数据,应用统计学方法对样本数据构成的same As网络进行结构分析、域名分析和实例类型分析。【结果】数据分析结果表明,真实数据网络中same As连接较稀疏,等同实体网络中大多数实体只建立了单个连接。【局限】样本数据数量有限,未能更全面地深入分析。【结论】该研究分析可以为关联数据中基于实例水平的数据集成、本体对齐、知识发现以及跨数据集查询等提供参考。

[Objective] This paper examines the application of the owl：same As link in the Web of Data. [Methods] First, we extracted owl：same As links from the BTC 2014 dataset. Then, we analyzed the structure of the sample data, as well as their domain names and instance types. [Results] The retrieved links of owl：same As were sparse, and most entities only had single connection between each other. [Limitations] The size of our sample data was small, and more comprehensive analysis was needed. [Conclusions] Our study lays some foundations for data integration, ontology alignment, knowledge discovery of the Web of Data.
