Abstract

The invention discloses a community structure discovery method and system for an e-mail network, belongs to the field of Web network data mining, and the method and the system are used for solving theproblem of community discovery in the e-mail network. The method comprises the following steps: carrying out E-mail network topology modeling based on an E-mail data set; randomly initializing the community label of each user in the e-mail network for multiple times, and generating a plurality of independent community discovery results of the e-mail network by utilizing a label propagation method; calculating the modularity of each independent community discovery result; calculating an integration weight of each independent community discovery result; and performing weighted integration on the plurality of independent community discovery results of the e-mail network to obtain an integrated community discovery result of the e-mail network. The method and the system have the advantages ofbeing simple in algorithm structure, easy to implement and high in execution efficiency, and the E-mail network community discovery result high in stability and reliability can be obtained by conducting consistency integration on the multiple independent community discovery results.

Description

technical field [0001] The invention relates to the technical field of Web network data mining, in particular to a method and system for discovering community structure of an email network. Background technique [0002] E-mail is a communication method for exchanging information by using electronic means. Its appearance greatly facilitates communication and exchange between people, and it is also a network communication method that is currently used frequently. E-mail can reflect the communication relationship of people in the real society to a large extent, so the network composed of a large number of e-mail senders and receivers is one of the components of the social network, which can be analyzed by means of social network analysis. Analytical processing. E-mail networks are usually in the behavior mode of internal communication and dynamic communication, similar to other social networks, which contain several community structures, and there are often close communication...
