Relationship Extraction

Relationship Extraction (RE) is a task that is related to Coreference Resolution but with a focus on identifying relationships between entities. 
 In the following example: 
 
 James, the CTO at Filament AI, lives in the South of England. 
 
 We want to identify the following relationships: 
 (James, isCTOof, Filament AI)
(James, livesIn, England)
 
 Approaches 
 
 
 FewRel by the NLP group at Tsinghua University propose a few-shot model which takes 2 entity mentions, in context, and N possible relationship types - it predicts which of the relationships is most likely to apply. It can also predict when none of the relationships are applicable.
