摘要
企业缺乏分析危机事件网络舆情的合适手段,是企业面对相关事件举止失措的重要原因。如何建立起一个高效的网络舆情分析模型,已经引起学界的广泛关注。文章筛选了用于评价企业危机事件网络舆情的十五个指标,建立了以舆情热度、危度、离散度为框架的指标体系,分析了指标之间的影响和关系,建立了贝叶斯网络模型。并通过案例数据验证了模型的可靠性。
The lack of appropriate methods to analyze public opinion on crisis event of enterprise is the essential cause of the awkward situation of enterprise. Scholars have already made their efforts to build an efficient model to analyze online public opinion. 15 related indicators are extracted in this article, and an index system that includes 3 dimensions which are heat of opinion, danger of opinion and dispersion of opinion is built. Afterward, we analyze the relations between the indicators and build a Bayesian network model. We obtain positive results which testify the reliability of our model from test using cases data.
