Abstract

The spread of hoax news has a negative impact on society and requires early detection of hoax news through classification. This research combines augmentation and classification methods. CNN is used to understand the relationship between adjacent words in part of the sentence, while BiLSTM understands the word order in the sentence as a whole, and attention block understands the global context simultaneously. This research requires large data through back translation and TextAttack techniques. Model performance evaluation is done by measuring accuracy, precision, recall, and f1-score values. The use of augmentation for hoax news data increases by 19.87%. Accuracy of 98.18% predicts most hoax news data correctly. Precision of 98.16% shows excellent accuracy in predicting both hoax and valid classes. Precision in the hoax class is higher than the valid class which is 98.45%, meaning that the model is right in predicting the hoax class. Recall 98.17% shows that it is sensitive to both hoax and valid classes. Recall of hoax class is higher than valid class which is 98.28% means the model is more sensitive to hoax class. F1-score of 98.46% shows a very good balance between precision and recall. The high f1-score value shows the consistency of the model in distinguishing hoax and valid classes. Based on the augmentation results, the number of data has increased from 20,292 to 24,324 data and the evaluation results of the combination of CNN architecture, BiLSTM and attention block can be categorized as very good in classifying hoax news in two classes.
