potential visitors better understand tourist attractions so that they can choose their favorite scenic spots and avoid and reduce trouble throughout the tour. For the reasons mentioned above, there is a need to study Japanese reviews of Chinese attractions to improve the service of tourist attractions. In the scientific communities worldwide, a growing number of studies have focused on sentiment analysis of online reviews. There is a great need for new tools and algorithms which can automatically, efficiently and robustly process the large amounts of user

assessed the effectiveness of the model against two real Twitter datasets. Sentiment analysis for Twitter textual data is also a hot topic. Two main methods have been utilized to classify the sentiment polarity: supervised machine learning method and rule-based method ( Hutto & Gilbert, 2014 ; Kim & Hovy, 2014 ). Tang et al. (2014) developed a new method that learned sentiment from specific word embedding and outperformed the previous top-performing system. Ren, Wang, and Ji (2016) used SVM for sentiment classification, and LDA was adopted for the improvement of
