Text classification model for methamphetamine-related tweets in Southeast Asia using dual data preprocessing techniques

Abstract: <span>Methamphetamine addiction is a prominent problem in Southeast Asia. Drug addicts often discuss illegal activities on popular social networking services. These individuals spread messages on social media as a means of both buying and selling drugs online. This paper proposes a model, the “text classification model of methamphetamine tweets in Southeast Asia” (TMTA), to identify whether a tweet from Southeast Asia is related to methamphetamine abuse.

“…The evaluation indicators of the civil aviation safety risk intelligent early warning model are Confusion, Accuracy, Precision, Recall, F1-Score, and Matthews correlation coefficient (MCC). The calculation formula of each evaluation index 27 is as follows:where TP represents true positive, FP represents false positive, FN represents false negative, and TN represents true negative. 28…”
