Classifying Short Text in Social Media: Twitter as Case Study

Faris Kateb, Jugal Kalita
2015 International Journal of Computer Applications  
Topics of interest include micro-blog summarization, breaking news detection, opinion mining and discovering trending topics.  ...  Short messages lead to less accurate results. This has motivated investigation of efficient algorithms to overcome problems that arise due to the short and often informal text of tweets.  ...  Classification is also affected by the huge number of short tweets spread out over many different topics, and hence, with many features. Static data is useful and easy to analyze.  ...
