基于时空分析的微博演化可视化

摘要

针对海量增长的微博信息不利于快速查阅和筛选的问题，在分析微博数据特点的基础上，利用数据挖掘技术和信息可视化技术的有机结合，开发了基于时空分析的微博演化分析系统。该系统侧重于对热点事件所涉及的微博信息的演化分析，在关注热点事件从发生、爆发到最终消亡的同时，更加关注当前热点的微博用户群体的情感分析、关键用户追寻、发布时序分析，并在侧重时间演化过程的同时关注于热点事件的空间地理信息分析。该系统广泛适用于普通微博用户、新闻机构、政府机关等单位。%Due to the massive growth in microblog information , it is difficult for user to check and select microblog information quickly .Based on the analysis of the microblog data characteristics , a MicroBlog E-volution Analysis System based on time and space was designed and developed according to the combina -tion of data mining technology and information visualization technology .This system focused on the mi-croblog evolution analysis of all the current hot spots involved , it paid more attention to the emotional a-nalysis of the current hot microblog group , key users and publish time series while focusing on the current hot spots from the emergence to outbreak and to finally die out slowly .It focused on spatial geographic in-formation analysis while putting emphasis on the time evolution process .The MicroBlog Evolution Analysis System can be widely used in ordinary microblog users , news agencies , government agencies and other departments .
