In April 2021, a series of strange phrases in journal articles piqued the interest of a group of computer scientists. The researchers could not understand why researchers would use the terms ‘counterfeit consciousness’, ‘profound neural organization’ and ‘colossal information’ in place of the more widely recognized terms ‘artificial intelligence’, ‘deep neural network’ and ‘big data’.
Further investigation revealed that these strange terms — which they dub “tortured phrases” — are probably the result of automated translation or software that attempts to disguise plagiarism. And they seem to be rife in computer-science papers.
Research-integrity sleuths say that Cabanac and his colleagues have uncovered a new type of fabricated research paper, and that their work, posted in a preprint on arXiv on 12 July1, might expose only the tip of the iceberg when it comes to the literature affected.
To get a sense of how many papers are affected, the researchers ran a search for several tortured phrases in journal articles indexed in the citation database Dimensions. They found more than 860 publications that included at least one of the phrases, 31 of which were published in a single journal: Microprocessors and Microsystems.
“It harms science. You cannot trust these papers, so we need to find them and retract them,” says Guillaume Cabanac, a computer scientist at the University of Toulouse, France, who worked on the study.
