Social media attracts all kinds of activities, including product marketing, celebrity marketing, and also it serves as platform for promoting political agenda. As it is gaining popularity from all various source, it has also attracted spammers and automated accounts that are responsible for spreading the misinformation and influencing the audience. In this context, there is a need to properly classify the social media account as bot account or human account. For classification and detection of social bots, different machine learning, deep learning techniques are implemented. In this paper, we have focused on ensemble technique for classification of social bot. Considering heterogeneous base classifier, such as decision tree, logistic regression and k-neighbor classifier, an ensemble model has been built, that combines the prediction of base classifier, and gives the final prediction. The ensemble approach that has been implemented are, majority voting, random forest and bagging with decision tree.
