欧洲如何下定决心？欧洲歌唱大赛中各国之间的联系、派系和兼容性
How does Europe Make Its Mind Up? Connections, cliques, and compatibility between countries in the Eurovision Song Contest
摘要：
我们研究了欧洲歌唱大赛中国家之间的复杂关系，通过重新铸造过去的投票数据的动态网络。尽管英国人倾向于感到与欧洲的距离，但我们的分析表明，英国与其他欧洲国家非常兼容，或者说是“协调一致”。同样令人惊讶的是，我们发现，其他一些核心国家，特别是法国，与欧洲其他国家明显“格格不入”。此外，我们的分析使我们能够证实一种普遍的看法，即存在着非正式的国家集团-然而，这些集团并不总是预期的集团，它们的存在也不能仅仅以地理上的接近为理由来解释。这个系统的复杂性是通过小组的“自我评估”过程出现的，而且没有任何中央控制器。因此，人们可能会推测，这种复杂性是许多现实世界的情况下，“代理人”群体建立自己的相互关系，从而最终决定自己的命运的代表。可能的例子包括个人团体、社会、政治团体甚至政府。
英文摘要：
We investigate the complex relationships between countries in the Eurovision Song Contest, by recasting past voting data in terms of a dynamical network. Despite the British tendency to feel distant from Europe, our analysis shows that the U.K. is remarkably compatible, or 'in tune', with other European countries. Equally surprising is our finding that some other core countries, most notably France, are significantly 'out of tune' with the rest of Europe. In addition, our analysis enables us to confirm a widely-held belief that there are unofficial cliques of countries -- however these cliques are not always the expected ones, nor can their existence be explained solely on the grounds of geographical proximity. The complexity in this system emerges via the group 'self-assessment' process, and in the absence of any central controller. One might therefore speculate that such complexity is representative of many real-world situations in which groups of 'agents' establish their own inter-relationships and hence ultimately decide their own fate. Possible examples include groups of individuals, societies, political groups or even governments.
