Questions about fields in the data example given

Hi, Since constructing my own data set, I want to confirm the number here indicates which sentence of the text is used as the summary, right?

Yes. The label refers to the index of the selected sentence in the text. Since the model focuses on extractive summarization, which extracts sentences from the document instead of generating new sentences, we only need the index of the selected sentence as the signal during the training phase.
