【目的】調研owl:same As連接在真實數據網絡中的配置和應用情況。【方法】從BTC 2014數據集中抽取部分數據,應用統計學方法對樣本數據構成的same As網絡進行結構分析、域名分析和實例類型分析。【結果】數據分析結果表明,真實數據網絡中same As連接較稀疏,等同實體網絡中大多數實體只建立了單個連接。【局限】樣本數據數量有限,未能更全面地深入分析。【結論】該研究分析可以為關聯數據中基于實例水平的數據集成、本體對齊、知識發現以及跨數據集查詢等提供參考。

[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.
