Your previous papers, as long as they are checked by HowNet, are included in the database of college students' joint papers, but the papers in this database are not found by HowNet.

The "duplicate checking and comparison database" of HowNet duplicate checking system is based on "HowNet retrieval database", but it is not limited to retrieval database, and its scope is more than retrieval database. All the graduate papers tested by using the vip5.3 or tmlc2 version of HowNet will be included in this "joint comparison database of academic papers" to detect the phenomenon that recent graduates plagiarize previous graduation papers. The "Joint Comparison Database of Academic Papers" only includes papers, not this year, but only every other year. Only the repeated content in repeated reports is displayed, but this library does not provide retrieval, and others can't search your paper, which can be assured.
