基于LDA的企业微博主题传播超网络建模及分析方法

摘要

综合利用微博内容及粉丝评论数据,对企业微博主题的传播效果进行研究.使用LDA主题模型发现微博内容及粉丝评论中的主题,在此基础上,通过建立内容关键词与粉丝评论关键词之间的映射,构建微博主题传播超网络(MTDSN)模型.基于MTDSN模型及各构成子网,分析微博传播重点主题、粉丝热点主题、有效传播热点词及有效传播核心词,并通过凝聚子群分析有效传播主题及其构成.以华为花粉俱乐部官微为实例,证明该模型及方法的有效性.%This study focuses on the dissemination of enterprise micro-blog topics through the integrative analysis of micro-blog content and fans' comments.First,topics of micro-blog contents and fans' comments are discovered based on the LDA topic model.Then a micro-blog topic dissemination super-network model(MTDSN) is proposed through establishing the maps between keywords of content and fans' comments.Based on MTDSN and the subnets,this paper suggests some methods to discover the main disseminating topics of micro-blogs,the hot topics of fans and their belonging keywords together with possibilities,and the effectively disseminated keywords.Furthermore,the coreeffectively-disseminated keywords are identified through network analysis.In the end,we take official micro-blog of HUAWEI Huafen Club as a case study to testify the effectiveness of the model and methods.
