How to implement the keyword extraction function of Baidu Wenxin Yiyan’s random statements in PHP development?

Baidu Wenxin Yiyan is a randomly displayed sentence, which is often used on the homepage, login page, etc. of the website. This function was also used in the movie "Your Name". The keyword extraction function can make the displayed sentences more relevant to the content of the website and increase the user's reading experience. Next, we will introduce how to use PHP development to achieve this function.

First, we need to obtain the API of Baidu Wenxinyiyan. On Baidu Open Cloud Platform (https://cloud.baidu.com/), you can find the corresponding API interface, fill in the application form, and then create an application.

In the PHP code, we need to first send a request through the curl method and get the data returned by the API:

function getDataFromAPI($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}

$url = 'https://api.example.com/'; // 替换成真实的API链接
$data = getDataFromAPI($url);

Next, we need to parse the JSON data returned by the API and extract it from it Key words.

$jsonData = json_decode($data, true);

if ($jsonData && isset($jsonData['content'])) {
    $content = $jsonData['content'];
    // 对$content进行关键词提取的操作
}

In the operation of keyword extraction from $content, we can use PHP's natural language processing tool package (such as TextRank PHP) to extract keywords.

require_once 'vendor/autoload.php'; // 引入TextRank PHP的autoload文件

$text = $content; // 这里将$content传入进行关键词提取
$textrank = new DevStarTextRankTextRank();
$result = $textrank->getOnlyKeyWord($text);

// 打印出关键词数组
print_r($result);

The above example uses the TextRank PHP toolkit for keyword extraction, and you need to install the corresponding library through composer first. You can add the following content to the composer.json file:

{
    "require": {
        "dev-star/text-rank": "^1.0"
    }
}

and then execute the composer install command to install related dependencies.

Finally, we can display the extracted keywords together with Wenxin Yiyan sentences on the web page:

echo "<p>关键词:" . implode(", ", $result) . "</p>";
echo "<p>文心一言:" . $content . "</p>";

In this way, we have realized Baidu Wenxin Yiyan through PHP development Keyword extraction function of random sentences.

It should be noted that the API links, keyword extraction toolkits, etc. in the above examples are schematic and need to be modified and adapted accordingly according to the actual situation. At the same time, in order to ensure the security and efficiency of the code, it is also necessary to perform parameter verification, exception handling and other operations on interface requests.

Hope the above examples can help you implement this function!
