Unscrambling Customer Recommendations: A Novel LSTM Ensemble Approach in Airline Recommendation Prediction Using Online Reviews

Abstract

Customer feedback is an essential criterion for upcoming customers to learn from their experience with a company’s products. Customer reviews and ratings also help companies improve performance and figure out new methodologies to provide better services. This research concentrates on customer reviews and ratings to investigate which product a customer evaluates and its association with its recommendations. This work predicts the user recommendations in two modules. The first module performs sentiment analysis of customer reviews using the long short-term memory (LSTM) model, which estimates the probability of the customer’s sentiment about the airline’s services. The second module experimented over only various service aspect ratings on different airline services provided by customers. These two modules ensemble together to determine the predictive recommendations of the airlines. The obtained results reinforce the essential theoretical contribution to the literature on service appraisal, online review, and recommendations. In addition, our proposed ensemble approach will be helpful to those practitioners who wish to use any proposal that will provide a quick and essential vision by bringing together customer-generated reviews and ratings, thereby helping them in strategy designing, service improvement, and post-purchases planning. Also, forthcoming travelers may benefit from this proposed approach by assimilating an aggregating view of service quality.
