Abstract:
Automatic hate-speech detection from big and almost growing content of social media is a challenge. In the recent years it has been proven that the use of Natural LanguageProcessing methods in combination with Machine Learning algorithms to detect hate-speech from other instances of offensive language outperforms other approaches. This paper empirically studies the application of AdaBoost meta-algorithm to boost performance of hate-speech detection problem in conjunction with Support Vector Machine and Decision Tree as weak learners. The execution of AdaBoost with Support Vector Machine as the classifier on a Twitter dataset achieved higher accuracy in comparison to Decision Tree as the classifier. Moreover, it is observed that the accuracy of the AdaBoost classification method is higher than the Logistic Regression algorithm, which has thehighest accuracy among all the classification algorithms for the hate-speech problem in the given Twitter dataset.
