Explaining Veracity Predictions with Evidence Summarization: A Multi-Task Model Approach
This addresses misinformation detection for social media users, but it appears incremental as it builds on existing neural models with added explainability.
The authors tackled automated fact-checking by proposing a multi-task neural model that explains its veracity predictions through evidence summarization, achieving performance evaluated on public datasets.
The rapid dissemination of misinformation through social media increased the importance of automated fact-checking. Furthermore, studies on what deep neural models pay attention to when making predictions have increased in recent years. While significant progress has been made in this field, it has not yet reached a level of reasoning comparable to human reasoning. To address these gaps, we propose a multi-task explainable neural model for misinformation detection. Specifically, this work formulates an explanation generation process of the model's veracity prediction as a text summarization problem. Additionally, the performance of the proposed model is discussed on publicly available datasets and the findings are evaluated with related studies.
