Input format

[sjoerd1999]

When generating an article using contexual_generate.py, you need to specify a list of variables in a .jsonl file(from what I deducted from the 'april2019_set_mini.jsonl' file):
"title", "text", "summary", "authors", "publish-date", "url", "domain", "warc_date", "split" and "inst_index".

Which of these variables actually influence the generation of articles and in what way?
I know "title" is the heading, and will be the main topic of the generated article, but do the other variables also contribute to the generation?
Also I can't find what "warc_date" and "inst_index" entail.

Thanks in advance!
