Copied to clipboard
| Challenge: | Recent explosion of false claims in social media has led to manual fact-checking initiatives . however, existing methods are inadequate to deal with the growing number of false content claims. |
| Approach: | They propose to model claims about images using a new dataset to examine the relationship between the image and the claim. |
| Outcome: | The proposed method improves on the baseline and will enable future research on fact-checking claims about images. |
EXAMS: A Multi-subject High School Examinations Dataset for Cross-lingual and Multilingual Question Answering (2020.emnlp-main)
Copied to clipboard
| Challenge: | EXAMS is a benchmark dataset for cross-lingual and multilingual question answering for high school examinations. |
| Approach: | They propose to use EXAMS to evaluate cross-lingual and multilingual question answering for high school examinations. |
| Outcome: | The proposed model can be used to explore multilingual reasoning and knowledge transfer methods and pre-trained models in schools in different languages, which was not possible by now. |

| Challenge: | Existing approaches to cross-lingual content flagging with limited target language data are lacking in many languages. |
| Approach: | They propose a framework for cross-lingual content flagging with limited target- language data based on a nearest-neighbor architecture and a transformer representation in all its components. |
| Outcome: | The proposed framework outperforms previous work in terms of predictive performance on eight languages from two different datasets. |
