ExtractionBased Text Summarization and Sentiment Analysis of Online Reviews Using Hybrid Classification Method The field of sentiment mining and text summarization has evoked the interest of many scientists and researchers over the last few years, as the textual data has become useful for many realworld applications and challenges. Sentiment Analysis and Opinion Mining is the most popular field for analyzing and discovering insights from text data from various sources, such as Facebook, Twitter and Amazon, Zomato, etc. It involves a computational study of an individualxe2x80x99s behavior in terms of buying interest and then extracting his opinions on the business entity of the company. This entity can be viewed as an event, individual, blog post or product experience. Scholars in the fields of natural language processing, data mining, machine learning and others have tested a variety of methods for automating sentiment analysis. These reviews are increasing on a daily basis, as a result of which the summarization of the reviews plays a role where the text is summarized as needed, which provides useful information from a large number of reviews. It is very difficult for a human being to extract and interpret useful data from a very large file. In the text analysis, the value of sentences is decided on the basis of the linguistic characteristics of sentences. This paper provides a comprehensive review of current and past work on sentiment analysis and text description. In this research work, a new hybrid classification system is proposed based on coupling classification methods using arcing classifiers and their quality is evaluated within terms of accuracy. The Classifier Collection was constructed using Naive Bayes (NB), Support Vector Machine (SVM) and Genetic Algorithm (GA). The proposed work consists of a comparative study of the efficacy of the ensemble technique for sentiment classification. The feasibility and benefits of the proposed approaches are demonstrated by a restaurant review that is widely used in the field of sentiment classification. A wide range of comparative studies is performed and, ultimately, some indepth analysis is addressed and conclusions are drawn on the efficacy of the ensemble technique for sentiment classification

Comparative Analysis for Arabic Sentiment Classification Sentiment analysis categorizes human opinions, emotions and reactions extracted from text into positive or negative polarity. However, mining sentiments from the Arabic text is challenging due to the scarcity of Arabic datasets for training the context. To address this gap, this study builds an Arabic sentiment dataset sourced from tweets, product reviews, hotel reviews, movie reviews, product attraction, and restaurant reviews from different websites; manually labeled for training the sentiment analysis model. The dataset is then used in a comparative experiment with three machine learning algorithms, which are Support Vector Machine (SVM), Naive Bayes (NB), and Decision Tree (DT) via a classification methodology. The best results for polarity prediction in sentiment analysis models was achieved by SVM with product attraction dataset, with the accuracy of 0.96, precision of 0.99, recall of 0.99, and Fmeasure of 0.98. This is followed by the average performance from NB and DT. It can be concluded that the ML classifiers need the right morphological features to enhance the classification accuracy when dealing with different words that play different roles in the sentence with the same letters.
