Finite state and Constraint Grammar based analysers and proofing tools, and language resources for the Finnish language

The Finnish morphology and tools

Download nightly / CI/CD installation packages for testing (contains the core zhfst file(s)):

NB!! Note that the nightly / CI/CD installation packages are not tested for language quality, and might contain regressions and errors.

This repository contains finite state source files for the Finnish language, for building morphological analysers, proofing tools and dictionaries. The data and implementation are licenced under GPLv3 licence, also detailed in the LICENSE. The authors named in the AUTHORS file are available to grant other licencing choices.

Install proofing tools and keyboards for the Finnish language by using the Divvun Installer (some languages are only available via the nightly channel).

Download and test speller files

The speller files downloadable at the top of this page (the *.bhfst files) can be used with divvunspell, to test their performance. These files are the exact same ones as installed on users' computers and mobile phones. Desktop and mobile speller files differ from each other in the error model and should be tested separately — thus also two different downloads.

Core dependencies

In order to compile and use Finnish language morphology and dictionaries, you need:

• an FST compiler: HFST, Foma or Xerox Xfst
• VislCG3 Constraint Grammar tools

To install VislCG3 and HFST, just copy/paste this into your Terminal on macOS:

curl https://apertium.projectjj.com/osx/install-nightly.sh | sudo bash

or terminal on Ubuntu, Debian or Windows Subsystem for Linux:

wget https://apertium.projectjj.com/apt/install-nightly.sh -O - | sudo bash
sudo apt-get install cg3 hfst

or terminal on RedHat, Fedora, CentOS or Windows Subsystem for Linux:

wget https://apertium.projectjj.com/rpm/install-nightly.sh -O - | sudo bash
sudo dnf install cg3 hfst

Alternatively, the Apertium wiki has good instructions on how to install the dependencies for Mac OS X and how to install the dependencies on linux

Further details and dependencies are described on the GiellaLT Getting Started pages.

Downloading

Using Git:

git clone https://github.com/giellalt/lang-fin

Using Subversion:

svn checkout https://github.com/giellalt/lang-fin.git/trunk lang-fin

Building and installation

INSTALL describes the GNU build system in detail, but for most users it is the usual:

./autogen.sh # This will automatically clone or check out other GiellaLT dependencies
./configure
make
(as root) make install

wrong superlative for Finnish 'halpa'

Hello! I am using giellalt indirectly, through uralicNLP. It seems to generate the incorrect superlative for Finnish 'halpa'. Finnish is not my native language, but according to the learning materials provided in my Finnish language class at university, and also according to Wiktionary, the superlative of 'halpa' should be 'halvin', and not 'halvoin'.

uralicNLP.generate(query="halpa+A+Superl+Sg+Nom", language="fin")

expected: [('halvin', 0.0)]
actual: [('halvoin', 0.0)]

missing past participle for "tietää"

Hello! I have learned that 'tiennyt' is the past participle of 'tietää'. giellalt says it's 'tietänyt'. While wiktionary also lists 'tietänyt', from what I understand, 'tiennyt' seems to be the more common form. Either way, I think that both forms should be generated and recognized.

from uralicNLP.uralicApi import generate
generate(query="tietää+V+Act+PrfPrc+Sg+Nom", language="fin")

expected output:
[('tiennyt', 0.0), ('tietänyt', 0.0)]

actual output:
[('tietänyt', 0.0)]

from uralicNLP.uralicApi import analyze
analyze(query="tiennyt", language="fin")

expected output:
[('tietää+V+Act+PrfPrc+Sg+Nom', 0.0)]

actual output:
[]

Generated non-normative verb forms

As seen e.g. at https://sanat.oahpa.no/detail/fin/nob/py%C3%B6r%C3%A4ill%C3%A4.html , the normative fst generates a number of non-normative verb forms, such as "(minä) pyöräelen".

Empty "lemma" in -toista compounds

Some of the compound analyses of numbers 11–19 contain an empty lemma followed by the tag +Cmp, such as

yksitoista	yksi+Num+Sg+Nom#+Cmp#toinen+N+Sg+Par
yksitoista	yksi+Num+Card+Sg+Nom#+Cmp#toinen+N+Sg+Par

Not sure if this is actually an error or intended, but it caused some problems in NDS, which expects the +Cmp tag to belong to a lemma. I am creating a guard there just in case anyways.
