摘要/Abstract

摘要： 针对恶意信息源覆盖范围重叠导致基于全网拓扑的定位算法复杂度高的情况，提出基于社区结构的子图划分算法，将恶意信息多源定位问题分解为多个单源定位问题。在此基础上，利用基于Jordan中心的在线社交网络多源定位算法，实现多个子图内的恶意信息单源定位。在随机数网络和UCIonline网络上的仿真结果表明，该算法能够有效识别恶意信息源，定位准确率相比基于距离中心、紧密度中心和介数中心的算法提高11%~30%。

Abstract: To address the high complexity of the location algorithm based on the topology of the whole network,which is led by a coverage overlap between malicious information sources,a subgraph division algorithm based on community structure is proposed.The algorithm decomposes the location problem of multi-source malicious information into multiple single-source location problems.On this basis,the multi-source location algorithm for Online Social Network(OSN) based on the Jordan center is used for the single-source malicious information location in multiple subgraphs.Simulation results on the random number network and UCIonline network show that the algorithm can effectively identify malicious information sources,and its location accuracy is 11%~30% higher than that of algorithm based on Distance Center(DC),Tightness Center(TC) and Betweenness Center(BC).

Key words: Online Social Network(OSN), malicious information, subgraph division, Jordan center, multi-source location
