How to Segment Words from a Text String in PHP

Without an efficient segmentation workflow in place, it’s extremely difficult to train Natural Language Processing (NLP) services. Thankfully, using the code examples below, you can easily take advantage of a free-to-use Word Segmentation API to streamline the segmentation process. The underlying service will return each word from the original input sentence in a list, also identifying the index, start position and end position of those words. Refer to the below JSON response model:

{
  "Words": [
    {
      "Word": "string",
      "WordIndex": 0,
      "StartPosition": 0,
      "EndPosition": 0
    }
  ]
}

To take advantage of this API, let’s first install the PHP client. We can do so with Composer by executing the following command:

composer require cloudmersive/cloudmersive_nlp_api_client

After that, let’s structure our API calls with the following examples:

<?php
require_once(__DIR__ . '/vendor/autoload.php');

// Configure API key authorization: Apikey
$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');



$apiInstance = new Swagger\Client\Api\SegmentationApi(
    
    
    new GuzzleHttp\Client(),
    $config
);
$input = new \Swagger\Client\Model\GetWordsRequest(); // \Swagger\Client\Model\GetWordsRequest | String to process

try {
    $result = $apiInstance->segmentationGetWords($input);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling SegmentationApi->segmentationGetWords: ', $e->getMessage(), PHP_EOL;
}
?>

To authenticate requests for free, grab a free-tier API key from our website; you can do so by registering a free account. Your free-tier API key will supply a limit of 800 API calls per month and no additional commitments (once you hit your limit, the total will reset the following month).
