Multi-granularity sequential neural network for document-level biomedical relation extraction

作者:

Highlights:

• We propose a sequential network via multi-granularity information to extract document-level biomedical entity relation, which tackles long-distance dependencies and complex contexts causing by numerous alias and inter-sentence relation.

• The proposed method can focus on entity pairs that precisely reflect the biomedical entity relation.

• Multi-granularity structural information is shown to be effective for document-level biomedical relation extraction by some analytical experiments.
