Does it Really Generalize Well on Unseen Data? Systematic Evaluation of Relational Triple Extraction Methods

no code implementations NAACL 2022 Juhyuk Lee, Min-Joong Lee, June Yong Yang, Eunho Yang

To keep a knowledge graph up-to-date, an extractor needs not only the ability to recall the triples it encountered during training, but also the ability to extract the new triples from the context that it has never seen before.
