praveen2593/Sentiment_analysis_twitter
Analyzed effect of Emoji's in improving Sentiment Analysis results. Collected twitter data using Twitter StreamAPI and used TF-IDF to vectorize the tweets. Created a positive and negative vector using the matrix, and used cosine similarity to identify the extent to which a given tweet is positive or negative. Incorporated Emoji's to the tweets by converting unicode, and repeated the process. Improved classification of the process by 15%.
