A Microblog Content Credibility Evaluation Model Based on the Influence of Sentiment Polarity

Abstract

False content in microblogs affects users’ judgment of facts. An evaluation of microblog content credibility can find false information as soon as possible, which ensures that social networks maintain a positive environment. The influence of sentiment polarity can be used to analyze the correlation between sentiment polarity in comments and Weibo content through semantic features and sentiment features in comments, to improve the effect of content credibility assessment. This paper proposes a Weibo content credibility evaluation model, CEISP (Credibility Evaluation based on the Influence of Sentiment Polarity). The semantic features of microblog content are extracted by a bidirectional-local information processing network. Bidirectional long short-term memory (BiLSTM) is used to mine the sentiment features of comments. The attention mechanism is used to capture the impact of different sentiment polarities in comments on microblog content, and the influence of sentiment polarities is obtained for the credibility assessment of microblog content. The experimental results on real datasets show that the evaluation performance of the CEISP model is improved compared with the comparison model. Compared with the existing Att-BiLSTM model, the evaluation accuracy of the CEISP model is improved by 0.0167.

Credibility Evaluation of User-generated Content using Novel Multinomial Classification Technique

“…In our daily lives, we come across a lot of information, and one of the characteristics we use to evaluate it is its trustworthiness, or believability (Aggarwal, 2022). Information credibility is described as one's perception of how trustworthy information is , and it is a powerful predictor of an information consumer's subsequent actions (Yao et al, 2022). Because large-scale collaborative creation is one of the keyways in which information is formed in the social network, user-generated material is sometimes viewed with suspicion; readers do not regard it as a reliable source of information.…”
