A Study on Semantic Shift of Uncivilized Words in Bullet-Screen Comments

Based on the theory of sentiment analysis and semantic prosody, this paper investigates the semantic shift of uncivilized words in bullet-screen comments by analyzing the sentiment polarity of co-occurrence emotional words. According to the swear level and frequency of uncivilized words in the bullet-screen dataset, six kinds of words are selected for analysis. Within both the bullet-screen dataset and the BCC corpus, the semantic shifts of prototypes and their alternative forms are gauged using the sentiment lexicon and the PMI-IR algorithm. The paper offers a statistical analysis of the semantic shifts observed in these uncivilized terms and subsequently delves into the underlying motivations for these shifts.
