Abstract  The traditional static methods of sentiment analysis cannot meet the quantity and complexity requirements of dynamic data in the big data era. Therefore, grounded on the concept of sequential three-way decisions, a sequential three-way sentiment analysis framework based on temporal-spatial multi-granularity is proposed to overcome the shortcomings of the traditional two-way decisions. Firstly, a multi-layer granular structure with temporal-spatial features is constructed using increasing data and better-fitting feature space over time to balance the misclassification cost and training cost. Then, three typical sentiment classification methods are applied as benchmarks to test the efficiency of the proposed method. Finally, compared with the static methods, experimental results on two datasets show that the proposed method greatly reduces the classification costs with the classification quality maintained.
