摘要:

我们开发的多重网络的小图分析,并讨论如何将这种分析可以扩展到多层和多级网络,以及与节点和/或链接的分类属性的图形。该分析已被改编为两个典型的例子复用:经济贸易数据表示为一个957-plex网络和75社交网络,每个表示为一个12-plex网络。我们发现,楔形(开放的三合会)更经常发生在经济贸易网络比在社交网络,表明一个国家的倾向,生产/贸易的产品在当地结构的三合会是不封闭的。此外,我们的分析提供的证据表明,小多样性的国家往往形成相关的三角形。楔形也出现在社交网络中,然而社交网络中的主导小图是三角形(闭合三元组)。如果一个多重结构表明一个强关系,图分析提供了另一个证据的概念,强/弱关系和结构洞。在对比的Granwartter的开创性工作的强度弱的关系,它已被证明,只有强关系的楔形是不存在的,在这里,我们表明,对于分析的75个社交网络,只有强关系的楔形不仅存在,而且显着相关。

英文摘要:

We develop graphlet analysis for multiplex networks and discuss how this analysis can be extended to multilayer and multilevel networks as well as to graphs with node and/or link categorical attributes. The analysis has been adapted for two typical examples of multiplexes: economic trade data represented as a 957-plex network and 75 social networks each represented as a 12-plex network. We show that wedges (open triads) occur more often in economic trade networks than in social networks, indicating the tendency of a country to produce/trade of a product in local structure of triads which are not closed. Moreover, our analysis provides evidence that the countries with small diversity tend to form correlated triangles. Wedges also appear in the social networks, however the dominant graphlets in social networks are triangles (closed triads). If a multiplex structure indicates a strong tie, the graphlet analysis provides another evidence for the concepts of strong/weak ties and structural holes. In contrast to Granovetter's seminal work on the strength of weak ties, in which it has been documented that the wedges with only strong ties are absent, here we show that for the analyzed 75 social networks, the wedges with only strong ties are not only present but also significantly correlated.
