Social network analysis (SNA) has been a research focus in multiple disciplines for decades, including sociology, health care, business management, etc. Traditional SNA researches concern more human and social science aspects trying to undermine the real relationship of people and the impacts of these relationships. While online social networks have become popular in recent years, social media analysis, especially from the viewpoint of computer scientists, is usually limited to the aspects of people¿s behavior on specific websites and thus are considered not necessarily related to the day-today people¿s behavior and relationships.
