假设我有两句话:

“敏捷的棕色狐狸跳过了懒狗”

“快速的棕色兔子跳过懒惰的猫”

有没有一种算法来检测这两个句子的相似度?例如:

function similarity_ratio($text1, $text2) {
code code code
return $similarity_ratio;
}
$text1 = "The quick brown fox jumps over the lazy dog";
$text2 = "The quick brown cat jumps over the lazy chicken";
echo similarity_ratio($text1, $text2);
// output 88%

function similarity_ratio($text1, $text2) {
     similar_text($text1, $text2, $similarity_ratio);
     return $similarity_ratio;
}

$text1 = "The quick brown fox jumps over the lazy dog";
$text2 = "The quick brown fox jumps over the lazy cat";
echo similarity_ratio($text1, $text2);

Output: 93.023255813953
