# UniMorph: The Universal Morphology Initiative

The [Universal Morphology (UniMorph) project](https://unimorph.github.io) is a collaborative 
effort to improve how NLP handles complex morphology in the world’s 
languages. The goal of UniMorph is to annotate morphological data
in a universal schema that allows an inflected word from any 
language to be defined by its lexical meaning, typically carried 
by the lemma, and by a rendering of its inflectional form in terms 
of a bundle of morphological features from our schema. The 
specification of the schema is described in [Sylak-Glassman (2016)](http://www.unimorph.org/doc/Sylak-Glassman_2016_-_UniMorph_Schema_User_Guide.pdf).

---

This tool provides turnkey command-line access to morphological annotations in over 100 languages.

To install the UniMorph Python extension, install it from PyPI:

 ```bash
 pip3 install unimorph
 ```

The tool will then be available to you from the command-line as `unimorph`. To see the features available, run `unimorph --help`.

## Usage

Query the available UniMorph languages' ISO 639-3 codes.

```bash
unimorph list
```

Give the complete paradigm for a lemma.

```bash
unimorph inflect --word recken --lang deu
```

Get a particular form of the lemma.

```bash
unimorph inflect --word recken --features V;IND;PRS;2;SG --lang deu
```

Analyze a word form: What are its lemma and features?

```bash
unimorph analyze --word gereckt --lang deu
```

(You can also use short param names.)

```bash
unimorph analyze -w gereckt -l deu
```

Records in UniMorph's inflectional databases cannot hope to exhaustively cover a language's lexicon, especially in light of novel words. If a word is missing, let us know.

## Contribution

UniMorph is an open project! We want you!

Found a bug? Want to contribute source code? Submit an issue or pull request to the appropriate [GitHub repository](https://github.com/unimorph). Language-specific corrections or additions should be marked in their corresponding repository; improvements to the `unimorph` command-line tool should be noted in the [`unimorph` repository](https://github.com/unimorph/unimorph).

## Advanced usage

`unimorph` stores language databases in a default location. This can be overridden by setting the shell environment variable `UNIMORPH` to the preferred folder.
