Abstract: According to the community detection in the email complex network,the DBSCAN algorithm was introduced into the email network to detect the community in this paper.Based on the analysis of the algorithm,the system architecture and algorithm implementation process of email network community detection were studied.Finally,the feasibility of the DBSCAN algorithm in electronic mail network community detection was verified by the test of the Enron email corpus.

Key words: Electronic mail network,Community detection,DBSCAN algorithm
