摘要:

News and social media messages usually contain subjective opinions conflicting with the needs of readers who want to receive objective information through public channels. To this end, the detection of subjectively biased sentences has become an important research issue. However, existing subjective bias detection approaches lack considering the syntactic structure and topical context of biased descriptions. In this paper, we propose a Subjective bIas deTection mEthod (SITE) that comprehensively fuses multiple bias-relevant information. Specifically, we first investigate the modification and lexical features of biased sentences, based on which we formulate a set of rules to characterize biased sentences. Then, we extract the semantic features of sentences using the BERT model, based on which we further mine topic features by clustering semantically similar sentences. Finally, we comprehensively characterize biased sentences by fusing such features and train a classification model to detect biased sentences in social media. We conducted a series of experiments on a public dataset, the results of which show that SITE can detect biased sentences with 86.2% accuracy, outperforming baseline methods. © 2023 Knowledge Systems Institute Graduate School.
