Sorry if this is a stupid question, but we are new to AI and I understand that we need to start annotating in the right way, to not have wrong answers in the future and need to start over.
Our scenario is that we need to do NER on contracts, to recognise the persons involved, value, dates, and some other entities specific to our business case.
My main question is that considering that 90% of the documents are 2 ou 3 pages, it's best to annotate the entire document at once, for thousands of documents or to "break" documents in minor statements and annotate this statements? It's important know this because if we can annotate the entire document, we can start now, but if we need to do some work before annotate, our work will increase.
The examples that I see is with minimal statements and my use case is a little different.
Another question that is related to the size of the text to annotate, is that if is better to have, for example, 20 labels in the SAME TEXT (For long texts) is OK or is better to "break" the text in small statements and annotate 2 or 3 labels at maximum for statement, makes difference?
Thanks in advance.
