A recent study has exposed a method of artificially inflating citation counts through “sneaked references,” which are extra citations included in metadata but not in the actual text of articles. This manipulation, uncovered in journals by Technoscience Academy, distorts citation metrics that are critical for research funding and academic promotions. The Conversation reports: The investigation began when Guillaume Cabanac, a professor at the University of Toulouse, wrote a post on PubPeer, a website dedicated to post-publication peer review, in which scientists discuss and analyze publications. In the post, he detailed how he had noticed an inconsistency: a Hindawi journal article that he suspected was fraudulent because it contained awkward phrases had far more citations than downloads, which is very unusual. The post caught the attention of several sleuths who are now the authors of the JASIST article. We used a scientific search engine to look for articles citing the initial article. Google Scholar found none, but Crossref and Dimensions did find references. The difference? Google Scholar is likely to mostly rely on the article’s main text to extract the references appearing in the bibliography section, whereas Crossref and Dimensions use metadata provided by publishers.
To understand the extent of the manipulation, we examined three scientific journals that were published by the Technoscience Academy, the publisher responsible for the articles that contained questionable citations. […] In the journals published by Technoscience Academy, at least 9% of recorded references were “sneaked references.” These additional references were only in the metadata, distorting citation counts and giving certain authors an unfair advantage. Some legitimate references were also lost, meaning they were not present in the metadata. In addition, when analyzing the sneaked references, we found that they highly benefited some researchers. For example, a single researcher who was associated with Technoscience Academy benefited from more than 3,000 additional illegitimate citations. Some journals from the same publisher benefited from a couple hundred additional sneaked citations.
We wanted our results to be externally validated, so we posted our study as a preprint, informed both Crossref and Dimensions of our findings and gave them a link to the preprinted investigation. Dimensions acknowledged the illegitimate citations and confirmed that their database reflects Crossref’s data. Crossref also confirmed the extra references in Retraction Watch and highlighted that this was the first time that it had been notified of such a problem in its database. The publisher, based on Crossref’s investigation, has taken action to fix the problem.
To combat this practice of “sneaked references,” the authors suggest several measures: rigorous verification of metadata by publishers and agencies like Crossref, independent audits to ensure data reliability, and increased transparency in managing references and citations.
There is hardly a thing in the world that some man can not make a little worse and sell a little cheaper.
