In this study, an automatic classification method based on the sentiment polarity of text is proposed. This method uses two sentiment dictionaries from different sources: the Chinese sentiment dictionary CSWN that integrates Chinese WordNet with SentiWordNet, and the sentiment dictionary obtained from a training corpus labeled with sentiment polarities. In this study, the sentiment polarity of ...

This paper presents a novel algorithm to compute sentiment orientation of Chinese sentiment word. The algorithm uses ideograms which are a distinguishing feature of Chinese language. The proposed algorithm can be applied to any sentiment classification scheme. To compute a word’s sentiment orientation using the proposed algorithm, only the word itself and a precomputed character ontology is req...

This paper describes our approach for SemEval-2017 Task 4 Sentiment Analysis in Twitter (SAT). Its five subtasks are divided into two categories: (1) sentiment classification, i.e., predicting topic-based tweet sentiment polarity, and (2) sentiment quantification, that is, estimating the sentiment distributions of a set of given tweets. We build a convolutional sentence classification system fo...

Sentiment analysis attempts to extract the author’s sentiments or opinions from unstructured text. Unlike approaches based on rules, a machine learning approach holds the promise of learning robust, highcoverage sentiment classifiers from labeled examples. However, people tend to use different ways to express the same sentiment due to the richness of natural language. Therefore, each sentiment ...

Sentiment analysis is an emerging research field. One of the major tasks of sentiment analysis is building sentiment lexicons and calculating their scores, which is an essential job that provides “material” for all sentiment analysis problems. In this paper, we propose a fuzzy language computation by taking linguistic context into account to provide an effective method for computing the sentime...
