Simpler is better? Lexicon-based ensemble sentiment classification beats supervised methods

Lukasz Augustyniak, Tomasz Kajdanowicz, Piotr Szymanski, Wlodzimierz Tuliglowicz, Przemyslaw Kazienko, Reda Alhajj, Boleslaw Szymanski
2014 2014 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining (ASONAM 2014)  
It has been shown in this paper that simplistic Bag of Words (BoW) lexicon methods for sentiment polarity assignment with ensemble classifiers are much faster than a supervised approach to sentiment classification  ...  BoW methods also proved to be efficient and fast across all examined datasets.  ...  Hence, the idea is to improve the efficiency of lexicon-based method by use of several lexicons, and by assembling classification provided by these simple and fast methods.  ...
