apertium2ud
Obtaining the mapping between the two tagsets based on the information from Apertium Wiki.
Loosely based on this code, hence the GPLv3 license.
To install, run
python -m pip install apertium2udThe latest uploaded version is 0.0.4.
NB! The latest version from PyPI (yes, you can install the tool via pip) is equipped with the apertium-kir .udx file rules.
To build the machine-readable mapping, run
python apertium_wiki_parser.pyApertium to Universal tags
>>> from apertium2ud.convert import a2ud
>>> tags = ["n", "pl", "acc"]
>>> a2ud(tags)
(['NOUN'], ['Number=Plur', 'Case=Acc'])
>>> tags_sophisticated = ["v", "tv", "ger", "nom", "cop", "aor", "p3", "pl"]
>>> a2ud(tags_sophisticated)
(['VERB', 'AUX'], ['Subcat=Tran', 'VerbForm=Vnoun', 'Case=Nom', 'Tense=Past', 'Person=3', 'Number=Plur'])
Universal tags to Apertium
So far the conversion is far from perfect

TODO
- Should sections
chunksand XML tags be added? No. - Tests: Apertium -> UD -> Apertium, UD -> Apertium -> UD (sometimes losses are inevitable)
- Add the possibility to add the rules based on a
.udxfile, which usually describes custom tags
