Sentiment analysis of tweets using kNN in r
Social networking sites has evolved as a major platform for people to express their opinions and sentiments on variety of topics like movies, politics issues, daily chores etc. This has made Social networking sites e.g. Facebook, Twitter rich with data, which can be used for opinion and sentiment mining. But mining of such unstructured text can be cumbersome and challenging. Hence I am motivated in this assignment to develop a model for sentiment and opinion analysis for twitter data.
