- Abstract:
-
In this study, the feature mining of online hotel review data is investigated. First, online hotel reviews data were obtained. To mine features from the review data, data cleaning, part-of-speech analysis, feature extraction, index determination, feature selection, feature determination, feature checking were carried out. Based on the word frequency, integrating part-of-speech analysis, and cluster analysis, the word frequency (TF), word frequency rate (TF1), word frequency weight (TTW), comment frequency (DF), inverse document frequency (IDF), and TF1-IDF of candidate feature words were applied to reduce dimension. The online hotel review data features were obtained, and then the feature words were verified. This paper will lay a solid foundation for the classification of hotels and customers and intelligent recommendation based on online reviews.
