“…Plagiarism as defined above refers to the intentional (covert) or unintentional (accidental) theft of published or unpublished intellectual property (i.e., words or ideas), whereas similarity index refers to “ the extent of overlap or match between an author's work compared to other existing sources (books, websites, student thesis, and research articles) in the databases of similarity checking tools. ” 9 24 The advancements in information technology has helped researchers get help from various freely available (i.e., Viper, eTBLAST/HelioBLAST, PlagScan, PlagiarismDetect, Antiplagiat, Plagiarisma, DupliChecker) and subscription-based (i.e., iThenticate, Turnitin, Similarity Check) similarity checking tools. 8 24 Many journal editors use iThenticate and/or Similarity Check (Crossref) for screening submitted manuscripts for similarity detection whereas Turnitin is commonly used by universities and faculty to assess text similarity in students' work; however, there is a fairness issue that not every journal or university, particularly those from developing countries, can afford to pay for using these subscription-based services.…”
