Does the Objective Matter? Comparing Training Objectives for Pronoun Resolution (2020.emnlp-main)
Copied to clipboard
| Challenge: | Pre-trained language models have been used to obtain state-of-the-art results on pronoun resolution. |
| Approach: | They propose to use pre-trained language models to train pronoun resolution models . they compare performance and seed-wise stability of four models that represent four objectives . |
| Outcome: | The proposed model performs best in-domain, while the other objectives perform poorly out-of-domain. |
WikiCREM: A Large Unsupervised Corpus for Coreference Resolution (D19-1)
Copied to clipboard
| Challenge: | Large-scale training sets for pronoun resolution are scarce, since manually labelling data is costly. |
| Approach: | They propose a language-model-based approach to solve pronoun disambiguation problems using a WikiCREM dataset. |
| Outcome: | The proposed model outperforms state-of-the-art approaches on 6 out of 7 datasets. |
Few-Shot Out-of-Domain Transfer Learning of Natural Language Explanations in a Label-Abundant Setup (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing approaches to train models to provide natural language explanations (NLEs) require acquisition of task-specific NLEs, which is time- and resource-consuming. |
| Approach: | They propose a few-shot out-of-domain transfer of NLEs from a parent task to a child task . they propose four methods that cover possible fine-tuning combinations of NLESs and labels . |
| Outcome: | The proposed methods cover the possible fine-tuning combinations of labels and NLEs for the parent and child tasks. |
A Surprisingly Robust Trick for the Winograd Schema Challenge (P19-1)
Copied to clipboard
| Challenge: | The Winograd Schema Challenge (WSC) dataset WSC273 and its inference counterpart WNLI are popular benchmarks for natural language understanding and commonsense reasoning. |
| Approach: | They propose to fine-tune language models on the Winograd Schema Challenge dataset WSC273 and its inference counterpart WNLI to achieve accuracies of 72.5% and 74.7%, respectively. |
| Outcome: | The proposed language models achieve 72.5% and 74.7% accuracy on the WSC273 and WNLI datasets, respectively. |
