In previous content-based classification researches which mainly center on the Chinese sentence structure and syntax analysis, we encountered such a fatal bottleneck: constantly newly-emerged words and usages. In fact, such a problem results from the complexity and flexibility of Chinese which is so different from English. Even some researchers solve this problem by building mathematical model (Abdullah & Wu, 2011), considering users’ relations in social network(Magnani, Montesi, & Rossi, 2010), or combining social network with RSS feeds (Phelan, McCarthy, Bennett, & Smyth, 2011a, 2011b; Phelan, McCarthy, & Smyth, 2009) (though they only recommend RSS news by tweets, we can easily reverse the idea by recommending tweets by RSS feeds), a subtle problem which is omitted is that people use microblog not only for the news which would appear on every portal site, but also for some social purpose (Chen, Nairn, & Chi, 2011; Zhao & Rosson, 2009).
