Abstract:

By using the method of emotional analysis, this paper analyzes the emotional characteristics of revolutionary figures' diaries, letters and other documents, and analyzes the development process of their revolutionary spirit, which is beneficial to further inherit the revolutionary tradition and carry forward the revolutionary spirit. This paper extracts and cleans the sentence data in Nie Er’s diaries and letters, uses the Senta model to identify the emotional characteristics of Nie Er, transforms the emotions into measurable values and visualizes them, and uses machine learning to study the characteristics of Nie Er’s emotional changes. From the perspective of data analysis, the emotional process of Nie Er’s revolutionary road is constructed. The study found that the three key events of witnessing the reactionaries’ suppression of teachers and classmates, personally experiencing the Battle of Shanghai and secretly joining the Communist Party of China had a profound impact on Nie Er’s emotional changes, and then formed his gradual decline period, fluctuation period, fluctuation recovery period and continuous improvement period. The four emotional stages of life reflect his life journey from establishing revolutionary consciousness to participating in the revolution and then to publicizing the revolution. It is believed that sentiment analysis provides a new method and perspective for the study of historical figures. By analyzing and displaying the interaction between the emotional process of the characters and the social background, it is helpful to explore the process of emotional change and the establishment and development of revolutionary spirit.
