The editors of web novels would check for duplicate copies when they accepted the articles. The editor would usually use some special duplicate checking tools to check if the text was similar to other texts. If they found a text with a high degree of similarity, the editor would consider excluding it to avoid confusion with other works. Specifically, editors would use some algorithms to analyze the text, such as using machine learning models to identify similarities or using manual review to check the similarities between texts. If there is a high degree of similarity between texts, editors may use tools to compare their grammar, vocabulary, and structure to ensure that they are different texts. The editor would usually double check the text multiple times to ensure its quality. Some editing tools also provided advanced functions such as detecting plagiarism, grammar errors, and spellings to further improve the quality of the text.
