We define “word-for-word plagiarism” as the author(s) takes a sequence of 6 or more words from another source without appropriate citation.
In order to prevent scholarly and professional plagiarism, we use the Crosscheck to check a suspected content. Alternatively, the editor may randomly sample 6 words from a suspected content, and do a Google search. If an exact match is found, the manuscript will be rejected.
