摘要
识别网络社区有影响力焦点话题是监测与引导网络舆情的基础。依据演化理论,构建网络社区话题演化分析模型,将话题贴及其回复关系视为话题贴吸收他人言论营养、聚集能量发挥作用的过程。主要通过筛选话题影响力测度指标,计算话题的营养值,将营养值转换为能量值,籍此发现有影响力的焦点话题,以形成网络社区有影响力话题度量识别方法,并采用实验法验证本文方法的有效性和合理性。
Identifying the influential focal topic in online community is the basis for Internet public sentiment monitoring. According to ageing theory, the authors build the topic evolution analysis model in online community, taking the interaction process between the post and its reply post as the process of the post absorbing nutrition for gathering energy, and calculate the influential value-energy value, from which we can find the influential focal topic and form the method of identifying the influential topic in online community. The au- thors also use examples to verify effectiveness and rationality of the method.
