TY - JOUR T1 - A Contrastive Learning Method for Automated Fact-Checking AU - Song, Seonyeong AU - An, Jejun AU - Park, Kunwoo JO - Journal of KIISE, JOK PY - 2023 DA - 2023/1/14 DO - 10.5626/JOK.2023.50.8.680 KW - automated fact checking KW - contrastive learning KW - sentence embedding KW - natural language processing AB - As proliferation of online misinformation increases, the importance of automated fact-checking, which enables real-time evaluation, has been emphasized. In this study, we propose a contrastive learning method for automated fact-checking in Korean. The proposed method deems a sentence similar to evidence as a positive sample to determine the authenticity of a given claim. In evaluation experiments, we found that the proposed method was more effective in the sentence selection step of finding evidence sentences for a given claim than previous methods. such as a finetuned pretrained language model and SimCSE. This study shows a potential of contrastive learning for automated fact-checking.
