Features
--------

[](#features)

- Morphological text processing via phpMorphy
- Named entity extraction (names, locations, organizations, abbreviations)
- Weighted scoring system with configurable coefficients
- File-based word cache for performance
- English, Deutsch and Russian language support

Installation
------------

[](#installation)

TextSimilarity is installed via [Composer](https://getcomposer.org/). To [add a dependency](https://getcomposer.org/doc/04-schema.md#package-links) to TextSimilarity in your project,

Run the following to use the latest stable version

```
composer require deevee15/text-similarity-php
```

Requirements
------------

[](#requirements)

- PHP 8.1 or above
- [phpMorphy library](https://github.com/cijic/phpmorphy)

Getting started
---------------

[](#getting-started)

```
use PHPTextSimilarity\TextSimilarity;

$result = TextSimilarity::compare(
    'en',
    'First article`s text...',
    'Second article`s text...',
    ['first' => "Article's title", 'second' => "Article's title"]
);
```

How it works
------------

[](#how-it-works)

The TextSimilarity library divides all words from compared texts and article titles into entities (proper names, common nouns, locations, abbreviations, organizations), converts them to the nominative case, then retains only the matching ones, assigns points based on the matches, and multiplies them by the importance coefficients specified in src/Config/WeightConfig.php.
