Corpus

Most of the training data are taken from literary texts, and especially plays, printed throughout the 17th century. Each print is described in depth in its own folder.

Transcriptions

Transcripts are almost diplomatic. Long ſ is maintained ( plaiſir and not plaisir). Ligatures which have disappeared ( ſt, st, ct) are not kept, but not those that are maintained in contemporary French (œ, æ).

For certain prints only, unicode and MUFI ligatures are maintained (folder 400dpi_mufi) for testing purposes. Ground truth is provided both with and without them.
