Entity Linking in 100 Languages (2020.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches to multilingual entity linking are cross-lingual, with a focus on zero-shot evaluation. |
| Approach: | They propose a new formulation for multilingual entity linking where language-specific mentions resolve to a language-agnostic Knowledge Base. |
| Outcome: | The proposed model outperforms state-of-the-art models on a large multilingual dataset and shows that frequency-based analysis provided key insights for the model and training enhancements. |

| Challenge: | a new dataset and evaluation benchmark for Few-shot Region-aware Machine Translation is presented . FRMT is a type of style-targeted translation that uses labeled training data to perform tasks. |
| Approach: | They propose a dataset and evaluation benchmark for Few-shot Region-aware Machine Translation. |
| Outcome: | The proposed model is based on two translations from English into Portuguese and Mandarin Chinese. |
Asking without Telling: Exploring Latent Ontologies in Contextual Representations (2020.emnlp-main)
Copied to clipboard
| Challenge: | Recent work on model analysis indicates that they may learn a lot about linguistic structure, including part of speech, syntax, word sense, and more. |
| Approach: | They introduce latent subclass learning, a modification to classifier-based probing that induces a latent categorization (or ontology) of the probe’s inputs. |
| Outcome: | The proposed model induces a latent categorization (or ontology) of the probe’s inputs without access to fine-grained gold labels. |
Learning To Split and Rephrase From Wikipedia Edit History (D18-1)
Copied to clipboard
| Challenge: | Performing split and rephrase tasks is one of the main operations in text simplification, alongside paraphrasing and dropping less salient content. |
| Approach: | They propose to use Wikipedia's edit history to extract a rich new dataset for the task. |
| Outcome: | The proposed model scores 32 BLEU points above the previous best on the WebSplit benchmark. |
