The type of duplicate checking of HowNet can be selected according to the type and purpose of the paper. Generally speaking, there are five types of paper inspection: professional title evaluation, academic research, academic publishing, graduation design and five other types of paper testing.

If it is a title evaluation, you can choose "paper topic and supporting results detection"; If it is the detection of scientific research achievements such as conference papers and project materials, you can choose "detection of scientific research achievements such as conference papers and project materials"; If it is periodical manuscript and book monograph detection, you can choose "periodical manuscript and book monograph detection"; If it is graduation project (thesis) detection, you can choose the detection type of "graduation project"; If it is another type of paper, you can select the "Other" type.

It should be noted that the personal duplicate checking service of HowNet does not support duplicate checking of graduate dissertations for the time being. As for graduate dissertations, you can choose paperfree free duplicate checking system to check the first draft, which provides free duplicate checking, machine weight reduction, online modification and other functions, covering about 70% of the data of HowNet, which can reduce the absolute cost of the previous duplicate checking fee.
