Abstract: Now days, Customer feedback and satisfaction is playing a significant role in commercial product to market. Customer can be reviewed by other customer feedback and collect all the relevant information related to a particular product. Based on that the decision can be taken to purchase the product. In the traditional method, Random forest predicted the impact of the review but not worked with segmentation on the basis of multiple reviewer comments. At the same time, the variable cluster algorithm has been addressed in the market segmentation for retailing the customer’s lifestyle. It has been provided with the segmentation method, but not guide to full proof strategies for different product decision. Instead of that to guide different customers with a variety of product feedback using pattern mining approaches. The product review pattern mining segmentation based on probabilistic principle component analysis is proposed. The opinion mining, segments has categorized into several segments with pattern analysis based on multiple review comments. This mechanism has reduced the dimensionality of the segmentation process using the covariance matrix approach. The experiment uses the opinion rank review dataset information for further process. It increases the segmentation efficient upto9% when compare with traditional and conventional methods. The experimentation has been done with the important factor of opinion decision threshold, false positive rate, segmentation efficiency and customer product ratio level along with customer behavioral feedback.
