基于Aging theory社交网络用户关注点交互影响演化模型

Evolution Model Considering Interactive Effect of User's Focuses on Social Network Based on Aging Theory

【目的/意义】研究社交网络平台用户关注点演化对掌握舆情,制定管理决策具有重要作用。【方法/过程】本文提出一种基于Aging theory的关注点交互影响演化模型。该模型将每阶段营养素重新设计为外部来源与其他关注点转移两类,使用关注点间的相似性作为第二类营养素度量演化过程中关注点交互影响效应,并根据两类营养素不同比例将关注点划分为突发型与渐变型两种。【结果/结论】通过"厦门BRT爆炸"的新浪微博数据集验证,该模型能够刻画上述两种关注点的演化趋势,并对演化原因进行解释。

【Purpose/significance】It＇s import to study the evolution of user＇s focuses on social network for catching public opinion and making management decision. 【Method/process】 This paper develops a model about evolution of focus considering interactive effect based on Aging theory. The nutrient is redesigned to divide external source and other focuses transfer, and the similarity of focuses as the latter is utilized to measure the interactive effect between focuses in process of evolving. And, the focuses are divides into two parts of sudden focus and gradual focus on the basis of two type of nutrient proportion.【Result/conclusion】According to the experiment on data of＂XIAMEN BRT EXPLOSION＂, the model can depict the trend of two types of focus and explain the reason of evolution.
