SpanRE: Entities and Overlapping Relations Extraction Based on Spans …
Weblearning to predict spans instead of single words [13]. Recently, some span-based models towards joint entity and rela-tion extraction have been proposed [20, 9], using span representa-tions derived from a BiLSTM over concatenated ELMo, word and character embeddings. These representations are then shared across the downstream tasks.
