ZurichNLP/mediomatix

General Information

Release of the Mediomatix corpus, prepared by UZH and PHGR, to be used for research purposes only.

Each segment is presented as part of a multi-parallel alignment. For the full, unaligned Mediomatix data in each idiom's schoolbooks, see here .

We use the following Romansh idiom codes as columns:

• Sursilvan: rm-sursilv
• Sutsilvan: rm-sutsilv
• Surmiran: rm-surmiran
• Puter: rm-puter
• Vallader: rm-vallader

Book names are encoded in the book column as follows:

• The first digit refers to the school year of the book
• The next refers to the book volums for that school year
• The two letter code indicates whether the segment comes from the student workbook ("wb") or teacher's commentary ("tc")
• Example: Book "5.1_tc" refers to teacher's commentary for Volume 1 of the year 5 schoolbook.

How to Use

To access all four splits, use the following code:

from datasets import load_dataset

# Load aligned dataset

mediomatix = load_dataset("ZurichNLP/mediomatix")

# Access Train set:

train_set = mediomatix['train']

# Access Validation set:

val_set = mediomatix['validation']

# Access Test set:

test_set = mediomatix['test']

# Access no-rm-surmiran split:

no_surm = mediomatix['no_surm']
