According to the Tutorial "Training a custom ENTITY LINKING model with spaCy" (20:33) this is the training data format for spaCy's Entity Linker:
TRAIN_DATA = ("Emerson was born on a farm in Blackbutt, Queensland.", {"links": {(0, 7): { "Q312545": 1.0 }}})
My search for open source annotation tool is not successful. Do you know an open source/free annotation tool for this format?
