Speech Title: Modern big data management over social media for fake news identification using deep mining with bi-directional LSTM-recurrent neural network
Abstract: Currently, social media is full of news and its size is increasing exponentially daily. However, most of the news are fake and such fake news creates problems for individuals and institutions. Moreover, fake news impact may cause damage from citizens' personal repute to a country's foreign relations. Several techniques have been reported to collect and detect fake text news on social media, but none are commercially feasible. This talk presents a deep learning classification model to detect news unreliable (fake) or reliable (true) using the fake text news benchmark dataset. The original data shape in ‘train.csv’ was 25114 but after pre-processing the data shape converted to 20800 and similarly from ‘test.csv’ data shape converted from 5880 to 5200. The 70% (13936) of the part of pre-processed data of ‘train.csv’ was used as a training sample and 30% (6864) was used as a validation sample. The bidirectional Long Short-Term Memory (Bi-LSTM) model was developed in this study to classify the news as unreliable (fake) or reliable (not fake) on pre-processed fake news dataset. The model performance is measured with different statistical methods and metrics. The proposed model obtained 99.8%, 99.9%, and 99.7% accuracy, sensitivity, and specificity from the training set. While 92%, 93%, and 91% accuracy, sensitivity, and specificity attained from the validation set. The FPR and FNR from the training part were found as 0.0004 and 0.0022 while 0.0698 and 0.0898 were found for the validation part. The present study achieved a high accuracy rate for identifying fake news. The proposed model can be helpful for researchers to detect whether the news is fake or true.
