GUEST EDITORS NOTE SPECIAL ISSUE ON COMMUNITY STRUCTURES IN NETWORKS: METHODS AND APPLICATIONS

摘要

Networks in various application domains exhibit an internal structure: they con-nsist of tightly connected components that are more loosely connected to the rest ofnthe network. These components, known as communities, offer to the network struc-ntural properties that have proven valuable in various application domains. Miningnsuch community structures is a valuable tool that can enhance the functionalitynof networks and applications. The uncovering of such structures is a fundamentalnproblem in complex networks and occurs in a variety of forms.
