| Challenge: | Named entity linking (NEL) is a challenging task due to the frequency of unseen and emerging entities, which necessitates the use of unsupervised or zero-shot methods. |
| Approach: | They propose to map speaker-attributed quotes to a unique identifier in a referent knowledge base and then use it to resolve the ambiguity. |
| Outcome: | The proposed method disambiguates 94% and 63% of the mentions on Quotebank and the AIDA-CoNLL benchmark, respectively. |
