Relational World Knowledge Representation in Contextual Language Models: A Review [PDF]
Conference on Empirical Methods in Natural Language Processing, 2021 Relational knowledge bases (KBs) are commonly used to represent world knowledge in machines. However, while advantageous for their high degree of precision and interpretability, KBs are usually organized according to manually-defined schemas, which limit
