Estonian resource grammar for the Resource Grammar Library (RGL) of Grammatical Framework (GF).
Note: This project is currently not being maintained, and the grammar is being improved directly in the RGL project (see https://github.com/GrammaticalFramework/gf-rgl/tree/master/src/estonian).
Tagged versions and zip-files with external resources are available at https://github.com/GF-Estonian/GF-Estonian/releases
To download only the GF files relevant for the resource grammar, execute:
mkdir -p api estonian
curl https://raw.githubusercontent.com/GF-Estonian/GF-Estonian/master/tools/download-gf-estonian.py | python
To build the PGF run:
make pgf_lang
If the building fails with an error message, then compile ResEst.gf first:
make clean
gf estonian/ResEst.gf
make pgf_lang
Running morphology tests:
cd tools/
bash test-mk.bash N ../data/nouns.6forms.csv
bash test-mk.bash N ../data/adj.6forms.csv
bash test-mk.bash V ../data/verbs.8forms.csv
Running syntax tests:
make clean
cd tests/
sh run_tests.sh
We started out with a fork from the Finnish resource grammar with the general plan to:
- translate the demo lexicon from Finnish to Estonian (
LexiconEst) - implement Estonian smart paradigms to replace the Finnish ones
- tweak the syntax to be Estonian
This has been mostly accomplished.
2 numbers and 14 cases.
2 * 14 forms (excluding parallel forms)
- 1-arg (sg nom): 91% correct
- 2-arg (sg nom gen): 95% correct
- 3-arg (sg nom gen part): 97% correct
- 4-arg (sg nom gen part, pl part): 98% correct
- 6-arg paradigm: 100% correct
- no parallel forms
Constructed in the same way as nouns, but have 3 degree forms.
3 * 2 * 14 forms + 2 (?) * 1 adverb forms
- 1-arg : 90% correct
- 2-arg : 93% correct
- 3-arg : 95% correct
- 4-arg : 97% correct
- comparative guessed: TODO: determine correctness
- TODO: superlative (not urgent)
Forms: 40 in total
- Present : Person * Number
- Imperfect : Person * Number
- Conditional : Person * Number
- Imperative : P2 Sg, P2 Pl, P3, P1 Pl, NegPl
- Passive : {Present, Past} * {Pos, Neg}
- Quotative : Active, Passive
- Past participle : Active, Passive
- Present participle: Active, Passive
- Infinitive : da * 2 cases ; ma * 5 cases
Smart paradigm constructors
- 1-arg paradigm (ma): 90% correct
- 2-arg paradigm (ma, da): 96% correct
- 3-arg paradigm (ma, da, b): 98% correct
- 4-arg paradigm (ma, da, b, takse): 99% correct

- tested using the MOLTO Phrasebook and ACE-in-GF applications
