Literal Copying
Literal copying refers to reproducing another work word for word, either in whole or in part, without appropriate citation, permission, or acknowledgment of the original source. Such copying may constitute plagiarism when the original source is not properly acknowledged.
Substantial Copying
Substantial copying refers to reproducing a substantial part of another work without appropriate citation or acknowledgment. In determining whether copying is substantial, both the quantity and quality of the copied material are considered. Plagiarism may occur when the essential or distinctive elements of another work are reproduced, even if only a relatively small portion has been copied.
Inappropriate Paraphrasing
Inappropriate paraphrasing occurs when an author reproduces the ideas, structure, arguments, or essential meaning of another work while changing only the wording or sentence structure without providing appropriate citation or acknowledgment.
Self-Plagiarism
Self-plagiarism refers to the substantial reuse of an author's own previously published work, text, data, or ideas without proper citation, acknowledgment, or disclosure. Authors must clearly identify and cite their previous publications when relevant material is reused.
