hello. i have a question on how to make train data. (NER)

[NuealYoon]

I was looking at the train_data.txt file to train the model.

("""It's a visually stunning movie, finding moments both macro and micro to highlight the beautiful imagination that "Star Wars" can evoke.""", {
'words': ['It', "'s", 'a', 'visually', 'stunning', 'movie', ',', 'finding', 'moments', 'both', 'macro', 'and', 'micro', 'to', 'highlight', 'the', 'beautiful', 'imagination', 'that', '"', 'Star', 'Wars', '"', 'can', 'evoke', '.'],
'entities': [(25, 30, 'PRODUCT'), (114, 123, 'WORK_OF_ART')],
'heads': [1, 1, 5, 4, 5, 1, 1, 1, 7, 10, 8, 10, 10, 14, 7, 17, 17, 14, 24, 24, 21, 24, 23, 24, 17, 1],
'deps': ['nsubj', 'ROOT', 'det', 'advmod', 'amod', 'attr', 'punct', 'advcl', 'dobj', 'preconj', 'amod', 'cc', 'conj', 'aux', 'advcl', 'det', 'amod', 'dobj', 'mark', 'punct', 'compound', 'nsubj', 'punct', 'aux', 'relcl', 'punct'],
'tags': ['PRP', 'VBZ', 'DT', 'RB', 'JJ', 'NN', ',', 'VBG', 'NNS', 'CC', 'JJ', 'CC', 'JJ', 'TO', 'VB', 'DT', 'JJ', 'NN', 'IN', '``', 'NNP', 'NNS', "''", 'MD', 'VB', '.'],
'cats': {'POSITIVE': True, 'NEGATIVE': False}
})

1. What does the number mean in 'entities'?

2. Do you have a document to read what'heads','deps','tags' and'cats' are?

 Thanks for reading.

1. numbers in 'entities' mean character offsets within the sentence.
2. you will find your answers in spacy documentation / training
