In this study, we examine the differences in public opinion posts of Twitter users including a mention on “Sewol ferry accident” in various political stances. We assume the selective exposure theory which states that a connection in Twitter is built between two users who shares similar political stance and the aggregation of all connections constructs a homogeneous network. Besides, twitter users may use the same term in different meaning and context according to their political stances. We apply social network analysis to identify user communities according to political stances and to evaluate the impact of the main players in each community by examining the frequent terms used in the communities. This results in not only structural implications but also semantic implications induced from the different opinions shown across homogeneous networks. Our results show the usefulness of the differences between online groups using network analysis method considering both structural and semantic perspectives. This study is expected to detect different political communities and to become a foundation of semantic network analysis.
