Abstract: Highlights•Joint extraction is to recognize biomedical entities and relations simultaneously.•Feature partition encoding divides neurons into entity, relation, shared partition.•Relative positional embedding benefits both entities and relations extraction.•FPE is effective in addressing the issue of overlapping triples in biomedicine.
