摘要:

我们假设,明确的上下文信息集成到一个多任务学习框架将强调上下文的重要性,以提高性能,共同学习命名实体识别(NER)和关系抽取(RE)。我们的工作通过将实体从其周围的上下文中分割出来并使用每个独立的片段构建上下文表示来证明这一假设。这种关系表示允许联合NER/RE系统在NER和RE任务上实现接近最先进(SOTA)的性能,同时在端到端NER和RE上以49.07 F1击败SOTA RE系统。

英文摘要:

We hypothesize that explicit integration of contextual information into an Multi-task Learning framework would emphasize the significance of context for boosting performance in jointly learning Named Entity Recognition (NER) and Relation Extraction (RE). Our work proves this hypothesis by segmenting entities from their surrounding context and by building contextual representations using each independent segment. This relation representation allows for a joint NER/RE system that achieves near state-of-the-art (SOTA) performance on both NER and RE tasks while beating the SOTA RE system at end-to-end NER & RE with a 49.07 F1.
