Lemmatizer
==========

[](#lemmatizer)

[![Build](https://github.com/AmaraLiving/lemmatizer/actions/workflows/ci-build.yml/badge.svg)](https://github.com/AmaraLiving/lemmatizer/actions/workflows/ci-build.yml)

A PHP library for getting a lemma from a given word, and getting a list of words that map to a lemma. This does NOT support part of speech specification.

Source data
-----------

[](#source-data)

This lemma dictionary is largely based on [WordNet](https://wordnet.princeton.edu/), a project maintained at Princeton University.

Demo
----

See the lemmatizer in action at

Usage in an application
-----------------------

[](#usage-in-an-application)

The included `index.php` file contains an interactive demo.

Make your code aware of the Lemmatizer class via your favorite method (e.g., `use writecrow\Lemmatizer\Lemmatizer;`)

Then pass a word into one of the two methods

```
print Lemmatizer::getLemma('leaves');
// Will print 'leaf'

print Lemmatizer::getWordsFromLemma('leaf');
// Will print 'leaves,leafing,leafed,leafs'
```

Testing
-------

[](#testing)

Unit Tests can be run (after `composer install`) by executing `vendor/bin/phpunit`
