A LITERATURE REVIEW OF CLUSTER THEORY: ARE RELATIONS AMONG CLUSTERS IMPORTANT?
回顾1259篇集群论文后，发现现有研究多从微观或中观层面讨论集群，提出研究集群间关系能加深理解，值得成为新方向。
Abstract Having reviewed 1259 papers on cluster theory, we find that current cluster studies primarily discussed cluster phenomena from either a microlevel or mesolevel. We argue that studying relations among clusters would increase our understanding of clusters, and such a research topic is worth becoming a new research orientation for cluster theory.
