網絡中的社區檢測在經濟和金融環境中起着至關重要的作用，特別是在應用於世界貿易網絡時。我們提供了一個新的視角，在這個視角中，通過一個特定的距離標準來識別相互作用強烈的國家集群。我們指的是埃斯特拉達的溝通距離和振動的溝通距離，特別適合捕捉經濟網絡的內部結構。該方法基於一個變化的距離閾值，從計算的角度來看是有效的。它還允許檢查簇間和胞內的性質產生的社區。數值分析突出了國家之間的特殊關係，並提供了一套豐富的信息，這些信息很難用其他的聚類方法來實現。

原文題目：Social and Information Networks：Communicability in the World Trade Network — A new perspective for community detection

原文：Community detection in a network plays a crucial role in the economic and financial contexts, specifically when applied to the World Trade Network. We provide a new perspective in which clusters of strongly interacting countries are identified by means of a specific distance criterion. We refer to the Estrada communicability distance and the vibrational communicability distance, which turn out to be particularly suitable for catching the inner structure of the economic network. The methodology is based on a varying distance threshold and it is effective from a computational point of view. It also allows an inspection of the intercluster and intracluster properties of the resulting communities. The numerical analyses highlight peculiar relationships between countries and provide a rich set of information that can hardly be achieved within alternative clustering approaches.
