Webis: an ensemble for Twitter sentiment detection describes a reimplementation of state-of-the-art method for Twitter sentiment analysis.

Reimplemented methods:

  1. NRC-Canada (2013): Emotions evoked by common words and phrases: Using mechanical turk to create an emotion lexicon
  2. GU-MLT-LT (2013): Sentiment analysis of short messages using linguistic features and stochastic gradient descent
  3. KLUE (2013): KLUE: simple and robust methods for polarity classification
  4. TeamX (2014): Teamx: a sentiment analyzer with enhanced lexicon mapping and weighting scheme for unbalanced data

The method showed superior performance in SemEval 2015 ("rank 1 among 40 systems")
