rhyme-suggester

Rhyme Suggester Php package

This package helps you to find the nearest object to your desired object, using edit-distance algorithm, specifically for phonetic of words. In the other words, this package will suggest closest elements of the database to the desired word based on it's pronunciation.

Installation

For installing this package, you just need to require it via composer in the root of your project:

composer require bdp-raymon/rhyme-suggester

Basic Usage

In order to getting familiar with the pacakge, we provided a small database in the samples directory. You just need to run codes bellow to see the rhytmic related words to امیر:

use BdpRaymon\RhymeSuggester\Rhyme;
use BdpRaymon\RhymeSuggester\Samples\Database as SampleDatabase;
use BdpRaymon\RhymeSuggester\PhpLibrary\Arr;

// this will return the array containing the nearest objects to the ‍‍`امیر`
$list = Rhyme::db(SampleDatabase::_)->filter();
$output = Arr::get($list, fn($value) => $value[0]['name']);
print_r($output);

The generated output should be something like this:

[
     "امیر",
     "عمید",
     "امین",
     "عزیز",
     "عقیل",
     "عقیق",
     "ادیب",
     "عفیف",
     "علیم",
     "اوین"
]

Full Usage

Feeding Database

You can feed database to the package with two different ways. First way have been already shown in the example above, with injecting it as an array to the static Rhyme::db function. Secondly, you can provide a .csv file of your own dataset and use it as an argument:

Rhyme::db("PATH-TO-THE-CSV-FILE.csv");

Configuration

The sample configuration file is placed in the samples/Config.php file. The fields that should be used in the config file are as follow:

• searchKey: (Required) It's the key that package uses to search your query to find the query object in the database. for example in our database, we use name key
• phoneticKey: (Required) The key in the database that we use edit-distance algorithm on it. Usually it should be the phonetic field.
• vowels: (Required) Specify the vowels of your language alphabet in a single string here.
• rhymeDistance: (Required) It's the distance between not important characters in the phonetic algorithm. we will discuss about it later.

Config file need to be set after instantiating an object of the Rhyme class, with following structure:

$config = [
    'searchKey' => 'name',
    'phoneticKey' => 'phonetic',
    'vowels' => 'aeiouā',
    'rhymeDistance' =>  0.1,
];
Rhyme::db($db)->setConfig($config);

Running a Query and Filtering

After specifying the database and configuration, you can run queries using filter function. This function allows customizing the search query with what you desire. Allowable fields in the filter array are as follow:

• config searchKey The search key you have configured as a config in previous step. In our example we used name key for searchKey.

• rhyme: (Required) The rhyme field accepts two values:

  • RhymeTypes::VOWEL
  • RhymeTypes::CONSONENT

  these two fields allow you to specify how the names would be suggested. In particular, it indicates which characters of the phonetics have lesser weight than the others in the edit-distance algorithm. If you choose VOEWEL, consonant characters will have the rhymeDistance weight, provided in the previous stage while the vowel characters value are equal to 1. And vice versa.

• selection: (Optional) Accepted values for this section are as follow:

  • SelectionTypes::FIRST
  • SelectionTypes::LAST
  • SelectionTypes::BOTH
  • SelectionTypes::NO

  These values specify which syllables of the phonetic should be used in the algorithm.FIRST indicates the first syllable should be used, and so on.

• similarity: (Optional) Similarity part force suggested names have the exaclty same parts specified with this attribute. It accepts following values:

  • SimilarityTypes::FIRST
  • SimilarityTypes::LAST
  • SimilarityTypes::NO

• tashdid: (Optional) If set to false, it will remove one of each two consecutive consonants in the phonetic. For example, it will turn abbās to abās.

• included: (Optional) If set true, it will suggest the words whether it is included to the query name or contains the query name.

• showDistance: (Optional) If set true, it will display the distances of the found words in the returned array.

• count: (Optional) You can specify number of words you want to receive with this option. Defaults to -1 that means will return every instance would be found.

Example

The complete working example should be something like this:

use BdpRaymon\RhymeSuggester\Rhyme;
use BdpRaymon\RhymeSuggester\Types\RhymeTypes;
use BdpRaymon\RhymeSuggester\Types\SelectionTypes;
use BdpRaymon\RhymeSuggester\Types\SimilarityTypes;
use BdpRaymon\RhymeSuggester\PhpLibrary\Arr;

$dbPath = __DIR__ . "/vendor/bdp-raymon/rhyme-suggester/samples/output_phonetic.csv";
$config = [
    'searchKey' => 'name',
    'phoneticKey' => 'phonetic',
    'vowels' => 'aeiouā',
    'rhymeDistance' =>  0.1,
];
$filter = [
    'name' => 'مهدی',
    'rhyme' => RhymeTypes::VOWEL,
    'selection' => SelectionTypes::NO,
    'similarity' => SimilarityTypes::FIRST,
    'tashdid' => false,
    'included' => true, 
    'showDistance' => true,
    'count' => 15,
];
$list = Rhyme::db($dbPath)->setConfig($config)->filter($filter);
$output = Arr::get($list, fn($value) => $value[0]['name']);
print_r($output);

And the output should be like this:

[
    "مهدی",
    "امیر مهدی",
    "مهدیس",
    "امیرمهدی",
    "اوتانا",
    "مهدیسا",
    "هستی",
    "فخری",
    "نرسی",
    "سلمی",
    "بدری",
    "زردیس",
    "تقی",
    "پردیس",
    "پری",
]

Tests

To run tests, use the following composer command:
