摘要翻译：
在自组织网络中，拓扑和动力学在一个连续的反馈中共同进化，没有外源驱动。世界贸易网络(WTN)是少数几个经验上有充分证明的自组织网络的例子之一：它的拓扑结构强烈地依赖于世界各国的国内生产总值，而国内生产总值又依赖于贸易结构。因此，了解WTN偏离随机性的关键拓扑性质可以提供关于自组织结构效应的直接经验信息。在这里，我们使用我们最近提出的一种分析模式检测方法，研究了1950-2000年间WTN中三元“模体”（三个顶点的子图）的出现。我们发现，与其他性质不同的是，模体并不是仅由入度和出度序列来解释的。相反，如果也考虑倒易边的数目，它们就完全被解释了。这意味着WTN演化的自组织过程几乎完全被编码为并元结构，并元结构强烈依赖于互易性。

分类描述：Covers the design, analysis, and modeling of social and information networks, including their applications for on-line information access, communication, and interaction, and their roles as datasets in the exploration of questions in these and other domains, including connections to the social and biological sciences. Analysis and modeling of such networks includes topics in ACM Subject classes F.2, G.2, G.3, H.2, and I.2; applications in computing include topics in H.3, H.4, and H.5; and applications at the interface of computing and other disciplines include topics in J.1--J.7. Papers on computer communication systems and network protocols (e.g. TCP/IP) are generally a closer fit to the Networking and Internet Architecture (cs.NI) category.

英文摘要：
  In self-organizing networks, topology and dynamics coevolve in a continuous feedback, without exogenous driving. The World Trade Network (WTN) is one of the few empirically well documented examples of self-organizing networks: its topology strongly depends on the GDP of world countries, which in turn depends on the structure of trade. Therefore, understanding which are the key topological properties of the WTN that deviate from randomness provides direct empirical information about the structural effects of self-organization. Here, using an analytical pattern-detection method that we have recently proposed, we study the occurrence of triadic "motifs" (subgraphs of three vertices) in the WTN between 1950 and 2000. We find that, unlike other properties, motifs are not explained by only the in- and out-degree sequences. By contrast, they are completely explained if also the numbers of reciprocal edges are taken into account. This implies that the self-organization process underlying the evolution of the WTN is almost completely encoded into the dyadic structure, which strongly depends on reciprocity.
