I'm sorry to have heard that. Your frustration can easily be understood.
You correctly identified the high number of false positives. Cross-check is
way far for being smart and I totally agree that we need better systems!
But from my associate editorial experience, I have found cross-check to be
a useful tool in identifying submissions which don't deserve even to be
submitted to a journal. Alas! for a handful of dishonest authors, each
manuscript now goes through an additional screening process. It's
unfortunate that the editorial manager of your journal had activated the
automated messaging rather than a manual check of the detected matches in
In my humble opinion, despite many publishing companies charge hefty amount
as 'article processing charge', the editorial and peer-review processes are
still community services; and there should be a system to stop bad paper to
be sent to the reviewers. Cross-check does that at an elementary level and
the responsibility goes to the journal editors to manually screen the
matches detected in the manuscripts and act accordingly.

> Dear Vision Community,
> during publishing of a recent manuscript, I received a request from the
> editorial office to alter a number of sections in said manuscript. The
> request was triggered by an automated plagiarism check using CrossCheck.
> The whole process left me so puzzled that I thought I‘d share my experience
> here, combined with a humble request for a broader debate about the issue
> of plagiarism in empirical research.
> First, what happened? The report contained a whopping 24 different items,
> each asserting plagiarism of the works of others. The email from the
> editorial office was phrased accordingly. It asked to “amend the affected
> sections by either identifying the fact that it has been reproduced or by
> using original words”, thus presuming all 24 instances of supposed
> plagiarism to be veridical. Most of them were not.
> After a very thorough debate about all 24 items with my co-authors and an
> expert for good scientific conduct at our university’s library, 22 out of
> all 24 items were discarded. The remaining 2 items were far from verbatim
> copies of whole sections. They were small parts of larger sentences
> together with explicit citations of the sources from which those parts were
> derived. The other 22 items were discarded not due to subjective reasoning
> but due to obvious glitches in the plagiarism checking algorithms. This
> amounts to a rate of 91.6% false positives. I’ll describe some of the more
> silly instances at the end of this text, but that is not the reason for my
> posting here.
> Instead, the point I very much like to discuss with you is the handling of
> possible plagiarism in empirical studies. Do we have an agreed code of
> conduct for authoring pieces of empirical science? Let me highlight only a
> few points.
> 1) How do we treat Materials and Methods? The Stimuli section will
> necessarily contain similar phrasings when reporting about research that
> uses identical paradigms. The Apparatus section will also be quite similar
> between related studies, as will the Participants section. The same holds
> for the Ethics Statement and the Measures and Analysis. Is it really
> desirable that we need to come up with ever so slightly different
> formulations for identical things, only to avoid verbatim copies? Are there
> not limitations as to how a temporal 2-AFC task can be described with
> appropriate brevity? And would it – particularly for Methods and Results
> –perhaps even be prudent to stick to a rather formulaic language protocol
> in order to make reception easier? I for one would certainly not wish to
> read a Methods section which goes like “Stimuli were created according to
> XY (2004). Handling of Participants was similar to XY (2010). Apparatus was
> as described in XY (1998). Task was taken from XY (2001). Analysis and
> measures are according to XY (1992).” This does not help me to efficiently
> understand what’s being done.
> 2) How do we handle self-citations? Many of us work on the same topics
> over long stretches of time, sometimes decades. Good scientific research
> usually means to advance present knowledge step by step, pulling only very
> few levers at once for each new experiment. Is it not to be expected that
> at some point we have arrived at concise, well-formulated, and most
> comprehensible ways to verbally introduce specific concepts. Is it really
> necessary that we find ever new ways to phrase the exact same ideas?
> 3) Is it the prime virtue of empirical research to be phrased originally?
> Is it not first and foremost the results and their implications that define
> original and interesting work? Even if we set high standards of originality
> for the prose in empirical articles, how should brief verbatim copies be
> handled? Let me give one example. Suppose, the abstract of a paper reads
> like “We used faces, non-face objects, Gabors, and colored Gaussian blobs
> to investigate the role of stimulus complexity on visual processing.” I
> find it highly questionable to then have a sentence like “XY (2001) used
> faces, non-face objects, Gabors, and colored Gaussian blobs to investigate
> the role of stimulus complexity.”, written by another author, qualify as
> plagiarism or needing quotes. Why should the latter author attempt to
> rephrase something that had already been so concisely summarized by the
> original authors?
> 4) Is it common consensus that automated plagiarism checking without
> editorial oversight is the yardstick against which to evaluate the
> originality of scientific manuscripts?
> I’d very much love to have an informed discussion with you. In part
> because I imagine that the plagiarism report I received may turn out to be
> the rule rather than the exception, hence we might all face hours of
> checking and re-checking during future publishing attempts.

> And here come some of the highlights from the plagiarism report issued to
> (i) My institutional address “Johannes Gutenberg University Mainz,
> Wallstr. 3, D-55122 Mainz, Germany” and the immediately following heading
> “Abstract” were flagged as plagiarism.
> (ii) The E-Mail addresses of the authors were flagged as a plagiarism.
> (iii) Citations and year numbers, e.g. “(Persike et al., 2015)” were
> included in the word count for multiple items. This had ridiculous
> consequences. To name only two of the most blatant ones: one plagiarism
> item was defined by the words “Author et al., 1993 […] et al. […] the […]
> et al., 1997” (with a few unflagged words inbetween), another item was
> defined by the words “Author1 and Author2, 1994; Author3 and Author4, 2001)
> (iv) Mathematical symbols, brand names and notational terms had been
> included in the report. One item therefore consisted almost entirely of
> parts of a mathematical formula, the product names “ViSaGe” and “ColorCal
> colorimeter”, the brand name “Cambridge Research Systems LLC”, the term
> “Michelson contrast”, and the phrase “were run in Matlab”.
> (v) Many of the report items contained common phrases used in neuroscience
> research, some of which were even multiply counted. For example, one item
> was defined by the mere phrase “to the ability of the visual system”,
> counted two times, plus a reference. A quick Google search turned up more
> than 150,000 hits for this exact phrase and Google Scholar yields more than
> a hundred authors who have also used this phrase in their works.
> (vi) The CrossCheck system invented false positives. One item contained
> the phrase “V2 neurons are highly selective”, another item referred to the
> phrase “to a particular combination of line components”. These phrases were
> not copied from anywhere but are original. In fact, they are so original
> that Google Scholar yields precisely zero search results for each of them.
> The sources from where these phrases were claimed to be derived do not
> include such sequences of words anywhere in the entire texts.
