How to use PHP to develop online plagiarism checking and article review modules in CMS

Nowadays, thousands of articles are published on the Internet every day, with rich and colorful content. However, this also brings up a serious question: How to prevent plagiarism and unreviewed articles from appearing on the website?

This is why most CMS developers will consider adding online plagiarism checking and article review modules. Both modules are very important to ensure that your CMS system meets strict quality standards.

So, how to use PHP to develop online plagiarism checking and article review modules in CMS? This article will provide you with some guidance.

1. Online duplication checking module

The purpose of the online duplication checking module is to compare whether the article to be published is similar to other articles or plagiarized. This module can help you ensure that the content published on your website is original and avoid duplicate content that affects search engine rankings and user experience.

In PHP, you can use the following code to implement online duplication checking:

function checkPlagiarism($text1, $text2)
{
    similar_text($text1, $text2, $percent);
    
    if ($percent > 90) {
        return true;
    } else {
        return false;
    }
}

In this code, the similar_text() function that comes with PHP is used, which is used to calculate two characters string similarity. If the string similarity is higher than 90%, it returns true, indicating that there is plagiarism or similar content.

In practical applications, all unreviewed articles only need to be compared with published articles one by one. This way, you can ensure that the content on your website is original.

2. Article review module

Once the article passes the online duplication check module, you can proceed to the next step: article review. The purpose of this module is to ensure that all published articles are appropriate, meaningful, and do not violate the site's rules and policies.

In PHP, you can use the following code to implement article review:

function verify($text) {
    //检验是否包含敏感词汇
    $badWords = array('敏感词汇1', '敏感词汇2', '敏感词汇3');
    foreach ($badWords as $word) {
        if (strpos($text, $word) !== false) {
            return false; //文章不合格
        }
    }
    
    //检验是否满足文章最小长度要求
    if (strlen($text) < 100) {
        return false; //文章不合格
    }
    
    //检查文章格式是否符合要求
    //这里可以使用正则表达式，判断文章是否包含标题、段落等元素，以及是否包含图片、链接等
    //省略具体代码
    
    //文章符合要求
    return true;
}

In this code, we ensure the quality of the article by adding sensitive words, limiting the minimum length, judging the article format, etc. . If the article does not meet the requirements, we can return false, otherwise the article can be published.

Summary

It takes a lot of time and energy to develop online plagiarism checking and article review modules, but these modules are very important to the quality of the CMS system. Only through these modules can we ensure that our CMS system contains high-quality content and maintain and protect our website reputation and brand image.

If you are developing a CMS system, do not ignore the existence of online plagiarism checking and article review modules. They will help you avoid some headaches while also ensuring that your website is of high standard and quality in terms of content.
