物理评论引文网络的社区结构
Community Structure of the Physical Review Citation Network
摘要：
我们调查了1893年至2007年8月间所有《物理评论》出版物的引文网络中物理学子领域的社区结构。我们专注于被引用的出版物（引用次数超过100次的出版物），并应用模块化最大化来发现与物理学的可明确识别的子领域相对应的主要社区。虽然社区之间的大多数联系都将那些具有明显知识重叠的社区联系起来，但由于广泛适用的理论技术的发展或理论与实验之间的交叉施肥，有时会在不同的领域之间存在意想不到的联系。我们还研究了十年的社区，并发现了在时间上广泛分离的社区之间的少数重要联系。
英文摘要：
We investigate the community structure of physics subfields in the citation network of all Physical Review publications between 1893 and August 2007. We focus on well-cited publications (those receiving more than 100 citations), and apply modularity maximization to uncover major communities that correspond to clearly-identifiable subfields of physics. While most of the links between communities connect those with obvious intellectual overlap, there sometimes exist unexpected connections between disparate fields due to the development of a widely-applicable theoretical technique or by cross fertilization between theory and experiment. We also examine communities decade by decade and also uncover a small number of significant links between communities that are widely separated in time.
