摘要
为了在网络论坛中提取意见领袖,文中通过抽象模拟论坛舆论意见领袖影响力的形成过程,建立了影响力向量模型,进而提出了可以利用影响力向量的模和方向这对参数来筛选意见领袖,并以天涯论坛某日的一个话题为研究个案,阐述了该参数的选择依据。再通过聚类分析比较不同类型的论坛舆论参与者的特点,将分析结果与提出模型筛选的结果相比对,论证文中方法结果的有效性和准确性,反应出文中提出参数的优越性。
To extract opinion leader from on-line forum, this paper, by simulating the formation process of the opinion leader＇s influence abstractly, models the influence with vector, and then proposes that it is possible to indentify, through the parameters of influence-vector model and direction the online forum opinion leaders. And with a topic appeared an Tian Ya forum some day as an example, the basis for selecting this pair of parameters is expounded. The result comparison with clustering analysis proves the effectiveness and accuracy of this method, also shows the advantage of this pair of parameters.
