Myths on Bi-direction Communication of Web 2.0 Based Social Networks: Is Social Network Truly Interactive

摘要

A new Social Interaction Monitoring System was developed based on the monitoring system that was developed in the previous project in which it focused on new contents created by the generators (i.e. online news, personal blog, and government agencies and departments). The SIMS focuses on monitoring social interactions by the followers, as well as new contents. It consists of smart crawler, section filter, dynamic scheduler, event detector , social interaction analyzer and MCRDR classifier. Korean Twitter service was monitored from October 2010 to February 2011 and user activities were analyzed. The results show very limited proportion of trend words are common among three services: Google Trend, Google News and Twitter, and Twitter is more closely related to Google News rather than Google Trends. Social network moves faster than conventional media as they directly reflect public opinions.
