Constructing Keyword Propagation Map of Facebook Pages

Social network visualization has been extensively studied in research in diffusion of information. This paper focuses on extracting propagated Facebook posts from keywords created by users and visualizing important information diffusion path in social network graph. Furthermore, some interesting propagation patterns of user behavior in online social network were discovered. Our research contributions could be summarized as follow: 1) A novel method was proposed to determine the keyword occurrence in online social network, 2) This research constructed the map of keyword propagation and visualized the propagation patterns among different groups of people and 3) a case study of social phenomena was shown. In sum, our work eventually could be applied to improve the performance of tracking keyword spread in social media and would be beneficial for greater understanding about user behavior.
