초록
Precise user-preference analysis is needed to generate a user profile for intelligent personal assistant. Aspect-level sentiment analysis can extract user preferences from product reviews but cannot explain the reasons for the user preferences because existing sentiment analyses only retrieve the polarity of a product feature. Further, it cannot consider the influence of sentiment words. Neutral sentiment words are not also utilized in sentiment analysis because these words do not affect the polarity calculation of the product feature. We propose a novel method that can analyze the root cause based on relations among words to extract the sentiment root cause. We use the fuzzy formal concept analysis to extend the feature-level hierarchy. A fuzzy cognitive map of the relations is employed to extract the root cause from the causes. The results show that we improved the accuracy of the sentiment cause and determination of the sentiment root-cause compared with the term frequency-based and sentiment score analyses.
