Mapping online social networks of Korean politicians

Korean politicians, particularly National Assembly members, have embraced the internet as a major means of communication for managing election campaigns and maintaining relationships with (potential) supporters during non-election periods. An increasing number of National Assembly members have become aware of the considerable influence that the internet has on their constituents, and thus, this study determines whether there are significant differences in online networks of National Assembly members and examines the relationship among National Assembly members and that between those members and their constituents to determine whether Twitter is used as a tool for communication as well as deliberation. The data were drawn from homepages, Hogs, and Twitter pages of the members of the 18th National Assembly in April 2010. The results indicate that National Assembly members tended to have a more equal relationship in the Twitter network than in the homepage or blog network. More importantly, the members were linked mainly to fellow politicians in the same party, and thus, they used Twitter to communicate more with fellow politicians than with their constituents.
