THE IMPLEMENTATION OF CUSTOMER SERVICE USING PUBLIC OPINION MINING

ABSTRACT

Today, digital reviews play a pivotal role in enhancing global communications among consumers and influencing consumer buying patterns. The availability of technology and infrastructure creates opportunities for citizens to publicly voice their opinions over social media. Business Company uses this opportunity to improve the quality of their product and the efficiency of their company. Companies don't yet have an effective way to make sense of customer opinions given on the product. Now a day‟s huge amount of product reviews are posted on the Web. Such product reviews are a very important source of information for business companies to know about their product acceptance by their customer. Manual analysis of these reviews is very difficult because of the increase in the number of reviews on products day after day. Techno Company creates a Facebook page that helps consumers to share their experiences and provide real insights about the performance of the product to future buyers. In order to extract valuable insights from a large set of reviews, classification of reviews and rating products into 1 for the best product which is highly accepted by their customer, 2 for a good product, and 3 for products having a problem which customers are not happy to buy it. is. Product Review Analysis is a computational study to extract subjective information from the text. This paper proposes a customer opinion analysis model to classify product reviews and rate the product as best, good, and bad based on customer feedback about the product. It applies six popular machine learning classifiers namely: Support Vector Machine (SVM), BOOSTING, SLDA, NNETWOR, TREE, and BAGGING with the aim to come up with the most efficient classifier. The dataset used consists of 2000 reviews about mobile phone products, collected from Tecno's Facebook page. In order to evaluate the six classifiers, we used 10fold cross-validation, recall, precision, F1-measure, and accuracy to measure the performance of each algorithm. The results showed that SVM and BOOSTING outperformed the other classifiers in terms of accuracy in all experiments. The decision Tree algorithm gave the lowest results across all experiments in terms of accuracy.
