多层知识图谱的中心性度量

Centrality Measures in multi-layer Knowledge Graphs

Jens Dörpinghaus, Vera Weil, Carsten Düing, Martin W. Sommer

摘要:

知识图谱在连接不同数据从而形成多个层次方面发挥着核心作用。因此,它们被广泛用于大数据集成,特别是用于连接来自不同领域的数据。很少有研究调查图中的多个层如何影响为单一目的网络(例如社交网络)开发的方法和算法。本文研究了与单一目的图相比,多层对中心性度量的影响。特别是,(a)我们开发了一个实验环境(b)评估两个不同的中心性措施-度和介数中心性-随机图的启发社会网络分析:小世界和无标度网络。所提出的方法(c)表明,图结构和拓扑结构对其存储的额外数据的鲁棒性有很大影响。虽然随机图的实验分析使我们能够进行一些基本的观察,但我们将(d)为对网络稳定性有重大影响的特定图结构的额外研究提出建议。

英文摘要:

Knowledge graphs play a central role for linking different data which leads to multiple layers. Thus, they are widely used in big data integration, especially for connecting data from different domains. Few studies have investigated the questions how multiple layers within graphs impact methods and algorithms developed for single-purpose networks, for example social networks. This manuscript investigates the impact of multiple layers on centrality measures compared to single-purpose graph. In particular, (a) we develop an experimental environment to (b) evaluate two different centrality measures - degree and betweenness centrality - on random graphs inspired by social network analysis: small-world and scale-free networks. The presented approach (c) shows that the graph structures and topology has a great impact on its robustness for additional data stored. Although the experimental analysis of random graphs allows us to make some basic observations we will (d) make suggestions for additional research on particular graph structures that have a great impact on the stability of networks.
