When a researcher submitted a manuscript to a journal about multimedia tools, she was frustrated to wait 13 months for the journal to make a decision — only to have it reject the paper outright. So imagine how she felt when, days after the paper was rejected, she saw the journal had published a plagiarized version of the paper by a group of different authors.
Clearly, something went very awry here — especially since the journal, Multimedia Tools and Applications (MTAP), has retracted three papers by the same group of authors, all of which plagiarized from unpublished manuscripts by other people.
Of course, one possibility is that an author was a peer reviewer of the manuscripts, and stole the unpublished material — something that unfortunately does happen.
There are four authors in common to all three manuscripts, but only one — corresponding author Chao Xiong of the Changzhou Institute of Technology in China — has responded to any queries from MTAP, according to the retraction notices. As the notices state, Xiong agrees with one of the the retractions, but not the other two. (All of the papers cover similar topics and were submitted around the same time, so it’s unclear why Xiong didn’t object to one retraction.)
Here’s a sample notice, for “Image-based reversible data hiding algorithm toward big multimedia data:”
We finally have some clarity on the case of the erroneous retraction over at the
