Abstract

Technology progresses every day, and millions of textual data points are created every second on the internet. Since the world is so interconnected today, people can use various web forums to find reviews of products before purchasing or renting them. Reviews and comments have a significant effect on a person’s purchase decision. Consequently, it is essential for a company to understand its customers’ behavior and attitudes toward its products and services and to use that information in sales, production, and marketing. This study examines how sentiments affect sales in the vehicle industry using the sentiment analysis component of Natural Language Processing (NLP). In the research the time series analysis to compare sales with sentiments is done to understand how both are connected, apart from this the lexical and pragmatic analysis of the reviews from the owners is done to understand their emotions about the vehicles they own. The Logistic Regression, Vader Sentiment Scoring, Roberta and neural network based models were created to predict the sentiments from a text review and the best model was selected based on the various evaluation metrics. Also it was found that the organizations shouldn’t depend only on the ratings to decide whether customer actually liked or disliked the product or the services.
