Recommendation Model Using User Reviews and Deep Learning Approach

Abstract— Due to the growing amount of information on the web, the information overload problem arises for users to discover relevant products easily and quickly. Collaborative Filtering (CF) is a recommender system which uses the user-item rating matrix to make suggestions to users by finding many users’ similar preferences. User reviews have information about products and users’ opinions than ratings. Using Opinion-based ratings in the rating prediction process of recommender system can reflect the detail preference of users effectively and accurately. In this paper, sentiment analysis is used to find the opinions of the user and matrix factorization that applied neural network is used to predict the ratings for the recommendation. The experiment is performed on the dataset of the hotel reviews and rating prediction accuracy is evaluated by measuring the prediction error called the Root Mean Square Error (RMSE).
