So you are saying that since it didn't, or cannot, know it was plagiarism that it cannot be plagiarism. Absolving the plagiarism due to programming. However, I already covered and disputed this earlier with the Accidental Plagiarism link. To refresh your memory here is the definition again.You are accusing Bard of a certain mens rea but you have not established it is capable of such guilty knowledge or even forming intent. It is a machine, not a human. Would you have me file a complaint against Bowser in Super Marios Bros for throwing fireballs at you?
"Accidental plagiarism occurs when a person neglects to cite their sources, or misquotes their sources, or unintentionally paraphrases a source by using similar words, groups of words, and/or sentence structure without attribution. (See example for mosaic plagiarism.) Students must learn how to cite their sources and to take careful and accurate notes when doing research. (See the Note-Taking section on the Avoiding Plagiarism page.) Lack of intent does not absolve the student of responsibility for plagiarism. Cases of accidental plagiarism are taken as seriously as any other plagiarism and are subject to the same range of consequences as other types of plagiarism." https://www.bowdoin.edu/dean-of-stu...nd-plagiarism/common-types-of-plagiarism.html
Is this definition from an academic setting and include possible punishment for students. Yes. Does this still define what accidental plagiarism is. Yes. Did Bard commit accidental plagiarism. YES!
