There were many ways to test the original content of an article, depending on the type of content and platform you wanted to test. Here are some common methods: 1. Comparing the original content: You can compare the original content, structure, and wording to determine whether the article plagiarized or borrowed from others. Online tools or software can be used to detect, for example, Google Translate, S-Scissors, etc. 2. Use manual testing: You can hire a professional manual testing system such as a machine translation company or a literary search engine. This method required a certain cost but was relatively accurate. 3. Use copyright protection tools: If the article involves copyright protection, you can use copyright protection tools to check the original degree of the article. These tools usually require a sample of the article to be tested according to copyright regulations. It should be noted that different platforms and tools may have slightly different methods for detecting the degree of originals. Therefore, before using any detection system, it was best to understand the detection method of the platform or tool in order to accurately detect the original degree.
