SOS: Systematic Offensive Stereotyping Bias in Word Embeddings (2022.coling-1)
Copied to clipboard
| Challenge: | Systematic Offensive Stereotyping (SOS) in word embeddings could lead to associating marginalised groups with hate speech and profanity. |
| Approach: | They propose a quantitative measure of the systematic offensive stereotyping (SOS) in word embeddings and validate it in most commonly used word embeds. |
| Outcome: | The proposed measure correlates with published statistics on online extremism, but does not explain hate speech detection models. |
Evidence Retrieval for Fact Verification using Multi-stage Reranking (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Existing evidence retrieval methods are limited by single-stage evidence extraction. |
| Approach: | They propose to use a multi-stage reranking paradigm to enhance the fact verification process by increasing the recall of sentences by 7.85%, tables by 8.29% and cells by 3% compared to the current state-of-the-art. |
| Outcome: | The proposed system outperforms state-of-the-art models and achieves a 93.63% recall rate for Wikipedia pages. |
