Sentimental Analysis of COVID-19 Related Messages in Social Networks by Involving an N-Gram Stacked Autoencoder Integrated in an Ensemble Learning Scheme

Abstract: The current population worldwide extensively uses social media to share thoughts, societal issues, and personal concerns. Social media can be viewed as an intelligent platform that can be augmented with a capability to analyze and predict various issues such as business needs, environmental needs, election trends (polls), governmental needs, etc. This has motivated us to initiate a comprehensive search of the COVID-19 pandemic-related views and opinions amongst the population on Twitter. The basic training dat… Show more

“…Sentiment analysis can be provided using again the machine learning approach and a lexicon-based approach. There are some works, which have used machine learning approach to sentiment analysis for example [ 25 ] have developed Ensemble Learning Scheme using DT, SVM, RF and KNN (K-Nearest Neighbours) for sentiment analysis of COVID-19 related comments. In work [ 26 ] deep learning models for sentiment analysis were used in recommender systems.…”

“…The input image from the dataset is preprocessed with Gabor Filter based Gaussian filter for noise removal and enhanced the image to improve the feature extraction and classification process. Gabor filter is a multi-resolution filter [20][21][22][23][24][25][26][27] for the removal of noise. It can be applied in various orientations and frequencies [28][29][30][31][32][33][34][35][36][37].…”
