This huge publicly available data can be used for research and a variety of applications. The objective of this paper is to counter problems with the social media dataset, namely : short text nature - the limited quantity of text data (140 to 160 characters), continuous streaming nature, usage of short forms and modern slangs and increasing use of sarcasm in messages and posts. Sarcastic tweets can mislead data mining activities and result in wrong classification. This paper compares various classification algorithms such as Random Forest, Gradient Boosting, Decision Tree, Adaptive Boost, Logistic Regression and Gaussian Naive Bayes to detect sarcasm in tweets from the Twitter Streaming API. The best classifier is chosen and paired with various pre-processing and filtering techniques using emoji and slang dictionary mapping to provide the best possible accuracy. The emoji and slang dictionary being the novel idea introduced in this paper. The obtained results can be used as input to other research and applications.
