摘　　要：针对中文微博目前已有的意见领袖识别模型存在的不足,提出一种特定话题转播网络中的意见领袖检测方法.识别模型通过转发关系建立信息传播网络,以用户自身权威值和转发用户的支持力来评价用户的影响力.通过对微博两周以来特定话题下意见领袖的检测实验,结果表明该方法能够有效地识别特定话题下的意见领袖.For the problems of the deficiency of existing recognition model of the Chinese weibo opinion leaders, one detection method of opinion leaders in a dissemination network of the specific topic is proposed. A recognition model based on the forward relations on the basis of information dissemination network is proposed in this paper, and the influence of users comes from their own authority and the support of forwarding user. An experiment of weibo opinion leader detection for about two weeks which is concentrated in a certain topic verifies that this method can effectively detect the opinion leader of the specific topic.
