In the duplicate check report of Geda's paper, the blue font represents the quoted fragments. If it is not a large area, if it is only a sentence or two, it will not necessarily be revised. The areas marked in red are the key modification areas, and some words can be modified by synonym replacement.

Paper duplicate checking system will provide users with a paper inspection report that records the paper duplication in detail after paper duplicate checking. Different inspection reports have different color labeling types. For the paperless duplicate checking system, blue will be used to mark the modified contents of the paper, that is, the quoted contents, and red will indicate the serious repetition of the contents in the paper.
