PHP LSA Library

Singular value decomposition in PHP implementation language.

This package can analyze texts to find a relation with given terms.

It can take an array with text document strings and transform them so they can be queried.

The package can also take a given text and perform a query to return the index of the document that matches better text that was given in the original array of text documents.

composer require vench/php-lsa

    $documents = [

            "the cow jumped over the moon",
            "the little dog laughed to see such fun",
            "and the dish ran away with the spoon",
     ];

     $lsa = new LSA(4);
     $trans = $lsa->fitTransform($documents);
     
     $query = "the brown fox ran around the dog";
     $index = $lsa->query($query, $trans);
     echo $documents[$index], PHP_EOL;
