Technical Summary of the Tool

Our tool uses a String-Matching Algorithm that breaks down text into tokens and compares the sequence of words. It identifies exact matches and near-identical phrases, providing a comprehensive similarity coefficient. This is essential for detecting "patchwork plagiarism" where a writer might change a few words but keep the original sentence structure.
