Having an average of five hundred million tweets sent out per day, twitter has become one of the largest platforms of data analysis for the researchers. Previously, various researches have been conducted on twitter data i.e., sentimental analysis. However, not much research has been done to classify the tweets in terms of categories so that tweets can be distributed as per user preferences. In this research we started by creating four broad categories: politics, sports, crime and natural. After that, we applied different machine learning techniques (Random Forest, K-Nearest Neighbors, Naive Bayes, Logistic Regression, Decision Tree and Support Vector Machine) to classify the twitter data. Finally, we compared the results in terms of sensitivity, specificity, precision, false positive rate and accuracy. We found that Support Vector Machine (SVM) produced the best results in terms of sensitivity, specificity, precision, false positive rate and accuracy. Hence, we concluded that a machine learning approach (Support Vector Machine) can certainly be used to classify twitter data.
