    "abstract": "This paper uses a database of collaboration recording between Econophysics\nScientists to study the community structure of this collaboration network,\nwhich with a single type of vertex and a type of undirected, weighted edge.\nHierarchical clustering and the algorithm of Girvan and Newman are presented to\nanalyze the data. And it emphasizes the influence of the weight to results of\ncommunities by comparing the different results obtained in different weights. A\nfunction D is proposed to distinguish the difference between above results. At\nlast the paper also gives explanation to the results and discussion about\ncommunity structure.",
