Create corpora for benchmarking #130

Open mweidling opened 2 years ago

mweidling commented 2 years ago

In order to execute the benchmarking we need some data with different characteristics to work on. @mweidling already has examined the OCR-D GT repository and wants to discuss with @tboenig and @cneud about useful corpora.

TODOs:

mweidling commented 2 years ago

This is a first naive overview of my GT categorization: gt_overview.ods.

If this isn't of that much use, I'll have a deeper look into that.

Here ist second, reviewed version of the sheet:

gt_overview.ods

EDIT: Replaced all instances of schwabacher with fraktur (20.09.22).

[1] We only have two works with text GT for the 19th century, blumenbach_anatomie_1805.ocrd and arnimb_goethe03_1835.ocrd. Since the 19th century isn't part of our scope, we'll limit ourselves to the material we already have.
