PHP MarkovChain Examples

Example #1

File: MarkovChainTest.php Project: fieg/markov

 public function testQuery()
 {
     $sentences = ['my blue car', 'red and blue flowers', 'his blue car'];
     $chain = new MarkovChain();
     foreach ($sentences as $sentence) {
         $tokens = explode(" ", $sentence);
         $chain->train($tokens);
     }
     $this->assertEquals(['car' => 0.66666666666667, 'flowers' => 0.33333333333333], $chain->query("blue"));
 }
