Zero-shot Cross-Language Transfer of Monolingual Entity Linking Models
Elliot Schumacher, James Mayfield, Mark H. Dredze · 2022
Most entity linking systems, whether mono or multilingual, link mentions to a single English knowledge base.Few have considered linking non-English text to a non-English KB, and therefore, transferring an English entity linking model to both a new document and KB language.We consider the task of zero-shot crosslanguage transfer of entity linking systems to a new language and KB.We find that a system trained with multilingual representations does reasonably well, and propose improvements to system training that lead to improved recall in most datasets, often matching the in-language performance.We further conduct a detailed evaluation to elucidate the challenges of this setting.
