Paper duplicate checking system detection
The paper duplicate checking system adopts semantic level detection technology, and there is no concept of "minimum detection unit". When the system identifies repeated and quoted content, it will judge the content that reaches a certain semantic level in combination with the content of the context, not just based on one or two words or a single sentence.
According to the algorithm, the system gets the complete content. Original plagiarism, rewriting and sentence order adjustment of document content can be automatically detected and identified, and can be quickly located and dynamically marked and displayed.
