Not sure if this is a good idea. Currently it is already somewhat vaguely defined.

I believe the original intention is to tell us something about the length (s2p: sentence to paragraph), but we know have the descriptive statistics which is a much better source.

However in MIEB it is used as "t2i", text to image.

@Muennighoff would love to know what you think:

here is a sampel from the desc. statistics:

...
        "average_document_length": 20.28592186371801,
        "max_document_length": 214210,
        "unique_documents": 1005474,
        "min_query_length": 2,
        "average_query_length": 38.259317745096176,
...

@isaac-chung you have also been involved greatly in both parts.

(an alternative is to convert the annotation in mieb into "s2i" meaning sentence to image)
