# Northern Sami and English: `apertium-sme-eng`

> **NB:** This system is an experiment sent for WMT shared task 2026, it is
> not meant as a production use translator at the current level. For more

This is an Apertium language pair for translating between Northern Sami and
English. What you can use this language package for:

* Translating between Northern Sami and English
* Morphological analysis of Northern Sami and English
* Part-of-speech tagging of Northern Sami and English

For information on the latter two points, see subheading "For more
information" below.

## Requirements

You will need the following software installed:

* autoconf
* automake
* pkg-config
* lttoolbox (>= 3.5.1)
* apertium (>= 3.6.1)
* vislcg3 (>= 1.3.1)
* hfst (>= 3.15.1)
* giella-sme
* apertium-eng

If this does not make any sense, we recommend you look at: apertium.org.

## Compiling

Given the requirements being installed, you should be able to just run:

```console
$ autoreconf -fvi
$ ./configure
$ make
# make install
```

You can use `./autogen.sh` instead of `autoreconf` and `./configure` in case
you're compiling from source. If you installed any prerequisite language
packages using a `--prefix` with `./configure`, make sure to use the same
`--prefix` when running `./configure` here.

If any of this doesn't make sense or doesn't work, see
<https://wiki.apertium.org/wiki/Install_language_data_by_compiling>

## Testing

If you are in the source directory after running make, the following
commands should work:

```console
$ echo "viessu" | apertium -d . sme-eng
house

$ echo "house" | apertium -d . eng-sme
viessu
```

After installing somewhere in `$PATH`, you should be able to do e.g.

```console
$ echo "viessu" | apertium sme-eng
house
```
