The growth of social website and electronic media contributes vast amount of user generated content such as customer reviews, comments and opinions. Sentiment Analysis term is referred to the extraction of others (speaker or writer) opinion in given source material (text) by using NLP, Linguistic Computation and Text mining. Sentiment classification of product and service reviews and comments has emerged as the most useful application in the area of sentiment analysis.This paper focuses on the comparative study (1997 -2012) of different sentiment classification techniques performed on different data set domain such as web discourse, reviews and news articles etc. The most popular approaches are Bag of words and feature extraction used by researchers to deal with sentiment analysis of opinion related to movies, electronics, cars, music etc. The sentiment analysis is used by manufacturers, politicians, news groups, and some organization to know the opinions of customer, people, and social website users.
To read the news, most smartphone users prefer social media over the internet. The news is posted on news websites, and the source of the verification is cited. The problem is determining how to verify the news and publications shared on social media platforms such as Twitter, Facebook Pages, WhatsApp Groups, and other microblogs and social media platforms. It is damaging to society to hold on to rumors masquerading as news. The request for an end to speculations, particularly in developing countries such as India, with a focus on authenticated, accurate news reports. This essay demonstrates a model and process for detecting false news. The internet is a significant invention, as well as a substantial number of individuals use it. These people use it for a variety of purposes. These users have access to a variety of social media platforms. Through these online platforms, any user can make a post or spread news. FAKE NEWS has spread to a larger audience than ever before in this digital era, owing primarily to the rise of social media and direct messaging platforms. Fake news detection requires significant research, but it also presents some challenges. Some difficulties may arise as a result of a limited number of resources, such as a dataset. In this project, we propose a machine learning technique for detecting fake news and implementing a novel automatic fake news credibility inference model with Natural language processing steps that include text mining. Machine learning algorithms construct a deep diffusive network model based on a set of explicit and latent features extracted from textual information to simultaneously learn the representations of news articles, creators, and subjects. The "Fake News Challenge" is a Kaggle competition, and the social network is using AI to sift fake news articles out of users' feeds. In the comparison study, three algorithms—Random Forest, Navy Bayes, and Passive Aggressive classifier—are used to determine the text accuracy value for the precision, recall, and f1 score using these methods. Finally, Passive Aggressive Classifier approach provides greater accuracy compared to others. Combating fake news is a traditional text categorization project with a simple proposition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
