README

这是一个PHP中用于识别相似字符串的基础库，无需使用机器学习。它可以让你从传递的句子集中获取一个主题的组。例如，像Google新闻那样结合不同出版物的新闻标题。

安装

在命令行中运行此命令

$ composer require esplora/similar

用法

我们需要通过传递一个闭包函数作为参数来创建一个对象，该闭包函数检查两个字符串是否相似

use Esplora\Similar\Similar;

$similar = new Similar(function (string $a, string $b) {
    similar_text($a, $b, $copy);

    return 51 < $copy;
});

注意，您不需要使用 similar_text。您可以使用其他实现，如 soundex 或其他。

然后我们必须调用 findOut 方法，传递一个包含字符串的一维数组

$similar->findOut([
    'Elon Musk gets mixed COVID-19 test results as SpaceX launches astronauts to the ISS',
    'Elon Musk may have Covid-19, should quarantine during SpaceX astronaut launch Sunday',

    // Superfluous word
    'Can Trump win with ‘fantasy’ electors bid? State GOP says no',
]);

结果将只有一个包含标题的组

'Elon Musk gets mixed COVID-19 test results as SpaceX launches astronauts to the ISS',
'Elon Musk may have Covid-19, should quarantine during SpaceX astronaut launch Sunday',

键

输入数组存储其键，以便您可以进行额外的处理

$similar->findOut([
  'kos' => "Trump acknowledges Biden's win in latest tweet",
  'foo' => 'Elon Musk gets mixed COVID-19 test results as SpaceX launches astronauts to the ISS',
  'baz' => 'Trump says Biden won but again refuses to concede',
  'bar' => 'Elon Musk may have Covid-19, should quarantine during SpaceX astronaut launch Sunday',
]);

结果将分为两个组

[
  'foo' => 'Elon Musk gets mixed COVID-19 test results as SpaceX launches astronauts to the ISS',
  'bar' => 'Elon Musk may have Covid-19, should quarantine during SpaceX astronaut launch Sunday',
],
[
  'baz' => 'Trump says Biden won but again refuses to concede',
  'kos' => "Trump acknowledges Biden's win in latest tweet",
],

对象

还可以传递对象以评估更复杂的条件。每个传递的对象必须能够通过 __toString() 方法转换为字符串。

$similar->findOut([
    new FixtureStingObject('Lorem ipsum dolor sit amet, consectetur adipiscing elit.'),
]);
