Improving Distantly-Supervised Relation Extraction through BERT-based Label & Instance Embeddings

1 code implementation1 Feb 2021 Despina Christou, Grigorios Tsoumakas

We propose REDSandT (Relation Extraction with Distant Supervision and Transformers), a novel distantly-supervised transformer-based RE method, that manages to capture a wider set of relations through highly informative instance and label embeddings for RE, by exploiting BERT's pre-trained model, and the relationship between labels and entities, respectively.
