Hi @hakunanatasha I have now made the relation arguments map to the entity ID so that we can uniquely resolve them. This is similar to the format used in ddi_corpus.

data["train"]["entities"][0][:5]
data["train"]["relations"][0][:5]

Will show the following entities

[{'id': '10072396-T1',
  'type': 'go',
  'text': ['nuclear'],
  'offsets': [[46, 53]],
  'normalized': [{'db_name': 'go', 'db_id': 'GO:0005634'}]},
 {'id': '10072396-T2',
  'type': 'go',
  'text': ['cytoplasmic'],
  'offsets': [[58, 69]],
  'normalized': [{'db_name': 'go', 'db_id': 'GO:0005737'}]},
 {'id': '10072396-T3',
  'type': 'taxonomy',
  'text': ['Arabidopsis'],
  'offsets': [[86, 97]],
  'normalized': [{'db_name': 'taxonomy', 'db_id': '3702'}]},
 {'id': '10072396-T4',
  'type': 'uniprot',
  'text': ['COP1'],
  'offsets': [[98, 102]],
  'normalized': [{'db_name': 'uniprot', 'db_id': 'P43254'}]},
 {'id': '10072396-T5',
  'type': 'taxonomy',
  'text': ['Arabidopsis'],
  'offsets': [[108, 119]],
  'normalized': [{'db_name': 'taxonomy', 'db_id': '3702'}]}]

And following relations:

[{'id': '10072396-R1',
  'type': 'localizeTo',
  'arg1_id': '10072396-T4',
  'arg2_id': '10072396-T2',
