| Title: Customer Reviews based Text Data Analysis for sentiment analysis | |
| Abstract:
Customers can learn more about a product’s quality through its reviews. Product rankings will change as a result of taking into account a variety of product review characteristics, such as product quality, content, duration of the review relative to the product’s longevity, and historically older good customer evaluations. On the other hand, a manual method on a wide scale is time-consuming, which results in an ineffective and unproductive way. Machine learning has been the most practical method for training the system in current era of artificial intelligence. Therefore, if a model were established to polarise those evaluations and learn from them, it would be lot simpler go through numerous comments. This paper presents a novel Genetic Optimized Multi-Class Hierarchy Binary-weighted Naive Bayesian(GO-MHBNB) approach to classify the customer reviews. It analyses the Amazon consumer reviews dataset for this research. To extract meaningful information like positivity or negativity from the raw data samples, stop word removal, tokenization, stemming, and lemmatization methods are used. This experiment is performed by employing the Python tool. Additionally, the proposed strategy is contrasted with current techniques in this study, including support vector machines (SVM), decision trees (DT), and random forests (RF). Findings demonstrated that the proposed approach produces effective resultsover the previous approaches with regards to accuracy, precision, recall, and f1-score for the classification of the customer reviews in positive, negative, and neutral reviews.
