Microblog Oriented Data Visualization Design And Implementation

Microblog is an information sharing, dissemination and access platform based on user relationship, users can easily express their views and exchange information with others on the network through the mobile computer visualization phone, network and other ways. In microblog each user is a source of information, which makes the amount of information carried by the microblog has greatly increased.Nowadays microblog is not just a simple social tool, it is gradually become a media which has faster progagation velocity than the mass media. A lot of news are spread from microblog earliest.Microblog has become a mapping from the real society to the virtual world and affect the life of every individual. Therefore, the research on the microblog has a very important significance.However, the information on the microblog is massive, complex, and diverse. Some of the traditional data analysis method has been difficult to adapt to the characteristics. Therefore, in this paper, we adapted data visualization focus to establish the means and methods to convey abstract information in an intuitive way. Automatic generation of visualization can reduce the human resources and improve the efficiency by using the computer, which has great significance to the development. Analyse, visualize the microblog data and provide human-computer interaction will be one of the most promising research direct.Based on the recently emerging 3 d tag cloud, realize a feeling of deja strong visual result, vivid image can show the weibo information details.In addition, this paper also by geographical information, the emotional topic on geographical position through visual display to the user, the user can according to the corresponding location on the topic the emotional tendency to speculate.The major work of this thesis is as follows:(1) Introduction of the basic method of data visualization and related technology;(2) Introduction of the TF-IDF algorithm for keyword extraction;(3) Introduction of the sentiment dictionary based emotional tendency analysis of Chinese microblog;(4) Analyse and visualize the collected microblog data using the technology mentioned above and complete three visualization product:(1)3D tag cloud;(2)Topic sentiment geographical distribution;(3)Topic keyword geographical distribution. In addition, this thesis also raises the prospective of the research.
