论文摘要
复杂系统的研究和理解是21世纪至关重要的智力和科学挑战。在这种情况下,网络科学已成为支持此类系统研究的数学工具。例子包括诸如野火之类的环境过程,这些过程以对人类生活的巨大影响而闻名。但是,从网络科学的角度来看,缺乏对野火的研究。在这里,采用按时间顺序的网络概念 - 一个时间网络,如果它们之间发生了两个连续事件,则将节点链接在一起 - 我们研究了动态社区结构揭示了有关野火动态的信息。特别是,我们探索了一种两相动态的社区检测方法,即,我们在一系列快照上应用了Louvain算法。然后,我们使用Jaccard相似性系数来匹配相邻快照的社区。进行了亚马逊基础上火灾事件的MODIS数据集的实验。我们的结果表明,动态社区可以揭示全年观察到的野火模式。
The study and comprehension of complex systems are crucial intellectual and scientific challenges of the 21st century. In this scenario, network science has emerged as a mathematical tool to support the study of such systems. Examples include environmental processes such as wildfires, which are known for their considerable impact on human life. However, there is a considerable lack of studies of wildfire from a network science perspective. Here, employing the chronological network concept -- a temporal network where nodes are linked if two consecutive events occur between them -- we investigate the information that dynamic community structures reveal about the wildfires' dynamics. Particularly, we explore a two-phase dynamic community detection approach, i.e., we applied the Louvain algorithm on a series of snapshots. Then we used the Jaccard similarity coefficient to match communities across adjacent snapshots. Experiments with the MODIS dataset of fire events in the Amazon basing were conducted. Our results show that the dynamic communities can reveal wildfire patterns observed throughout the year.
