Papers with coreference system
Coreference Resolution through a seq2seq Transition-Based System (2023.tacl-1)
Copied to clipboard
| Challenge: | Recent coreference resolution systems use search algorithms to identify mentions and resolve coreference. |
| Approach: | They propose a text-to-text coreference resolution system that uses a semantic paradigm to predict mentions and links jointly. |
| Outcome: | The proposed system achieves state-of-the-art accuracy on CoNLL-2012 datasets with 83.3 F1-score for English, 68.5 F1 score for Arabic, and 74.3 F1 scores for Chinese. |
Gender Bias in Contextualized Word Embeddings (N19-1)
Copied to clipboard
| Challenge: | Existing studies show that training word embeddings in large corpora could lead to encoding societal biases present in these human-produced data. |
| Approach: | They conduct several intrinsic analyses to quantify, analyze and mitigate gender bias exhibited in ELMo’s contextualized word vectors. |
| Outcome: | The proposed method mitigates gender bias on WinoBias probing corpus and demonstrates that it can be implemented in other systems. |
A Probabilistic Annotation Model for Crowdsourcing Coreference (D18-1)
Copied to clipboard
| Challenge: | Existing methods to generate annotated corpora for coreference are expensive and limited. |
| Approach: | They propose a model of annotation for aggregating crowdsourced anaphoric annotations. |
| Outcome: | The proposed model can extract from crowdsourced annotations coreference chains comparable to those obtained with expert annotation. |
