Copied to clipboard
| Challenge: | Mis- and disinformation online are a major source of harms of different kinds . out-of-context information is where different pieces of information are falsely associated . past studies have attempted to defend against OOC mis- and deinformation through external evidence, but they disregard the role of different pieces with different stances. |
| Approach: | They propose a stance extraction network that can extract stances of different pieces of evidence in a single framework. |
| Outcome: | The proposed model outperforms the state-of-the-art models on a public large-scale dataset with a performance gain of 3.2% in accuracy. |
