Reading and Reasoning over Chart Images for Evidence-based Automated Fact-Checking

Mubashara Akhtar,

Abstract: Evidence data for automated fact-checking (AFC) can be in multiple modalities such as text, tables, images, audio, or video. While there is increasing interest in using images for AFC, previous works mostly focus on detecting manipulated or fake images. We propose a novel task, chart-based fact-checking, and introduce ChartBERT as the first model for AFC against chart evidence. ChartBERT leverages textual, structural and visual information of charts to determine the veracity of textual claims. For evaluation, … Show more

“…In the future, we plan to enhance QACHECK 1) by integrating additional knowledge bases to further improve the breadth and depth of information accessible to the system (Feng et al, 2023;Kim et al, 2023), and 2) by incorporating a multimodal interface to support image (Chakraborty et al, 2023), table (Chen et al, 2020;, and chart-based fact-checking (Akhtar et al, 2023), which can broaden the system's utility in processing and analyzing different forms of data.…”
