Description
Opinion mining and sentiment analysis has been one of the attracting topics of knowledge mining and natural language processing in recent years. The problem of rating product aspects from textual customer reviews is an important task in the field of opinion mining and sentiment analysis. Previous studies have usually used rules of rating and have assumed that the rating scores are integers, that cause the time costs and low accuracy. In this paper, we propose a model based on neural networks for rating (or ranking) product aspects with rating scores are reals. The experimental results show the effectiveness of our proposal on computational times and accuracies in comparison with previous studies using model Perceptron classifier or nonlinear regression model (using Support Vector Regression). Our experiments are carried out on the hotel services extracted from the system Tripadvisor with the aspects including cleanliness, location, service, room, and value.
