Resumen
Online customers? opinions represent a significant resource for both customers and enterprises to extract much information that helps them make the right decision. Finding relevant data while searching the internet is a big challenge for web users, known as the ?Problem of Information Overload?. Recommender systems have been recognized as a promising way of solving such problems. In this paper, a product recommendation system called ?SmartTips? is introduced. The proposed model is built based on aspect-based sentiment analysis, which exploits customers? feedback and applies the aspect term extraction model to rate various products and extract user preferences as well. Several factors were considered, including readers? votes, aspect term frequency, opinion words? frequencies, etc. We tested our model on benchmark datasets that are widely used, and the results show that it outperforms the baseline methods regarding the mean squared errors of generated predictions.
