These benefits are internal to Wikimedia and a completely separate issue
from third-party re-use of Wikidata content as a default reference source,
which is the issue of concern here.

The quality of three-quarters of the 280+ Wikipedia language versions is
about at the level the English Wikipedia had reached in 2002.

Even some of the larger Wikipedias have significant problems. The Kazakh
Wikipedia for example is controlled by functionaries of an oppressive
regime[1], and the Croatian one is reportedly[2] controlled by fascists
rewriting history (unless things have improved markedly in the Croatian
Wikipedia since that report, which would be news to me). The Azerbaijani
Wikipedia seems to have problems as well.

The Wikimedia movement has always had an important principle: that all
content should be traceable to a "reliable source". Throughout the first
decade of this movement and beyond, Wikimedia content has never been
considered a reliable source. For example, you can't use a Wikipedia
article as a reference in another Wikipedia article.

Another important principle has been the disclaimer: pointing out to people
that the data is anonymously crowdsourced, and that there is no guarantee
of reliability or fitness for use.

Both of these principles are now being jettisoned.

Wikipedia content is considered a reliable source in Wikidata, and Wikidata
content is used as a reliable source by Google, where it appears without
any indication of its provenance. This is a reflection of the fact that
Wikidata, unlike Wikipedia, comes with a CC0 licence. That decision was, I
understand, made by Denny, who is both a Google employee and a WMF board
member.

The benefit to Google is very clear: this free, unattributed content adds
value to Google's search engine result pages, and improves Google's revenue
(currently running at about $10 million an hour, much of it from ads).

But what is the benefit to the end user? The end user gets information of
undisclosed provenance, which is presented to them as authoritative, even
though it may be compromised. In what sense is that an improvement for
society?

To me, the ongoing information revolution is like the 19th century
industrial revolution done over. It created whole new categories of abuse,
which it took a century to (partly) eliminate. But first, capitalists had a
field day, and the people who were screwed were the common folk. Could we
not try to learn from history?

At the recent Wikiconference USA, a Wikimedia veteran and professional
librarian expressed the view to me that

* circular referencing between VIAF and Wikidata will create a humongous
muddle that nobody will be able to sort out again afterwards, because –
unlike wiki mishaps in other topic areas – here it's the most authoritative
sources that are being corrupted by circular referencing;

* third parties are using Wikimedia content as a *reference standard *when
that was never the intention (see above).

I've seen German Wikimedians express concerns that quality assurance
standards have dropped alarmingly since the project began, with bot users
mass-importing unreliable data.

This sounds like "Let's do it quick and dirty and worry about the problems
later".

I sometimes get the feeling software engineers just love a programming
challenge, because that's where they can hone and display their skills.
Dirty data is one of those challenges: all the clever things one can do to
clean up the data! There is tremendous optimism about what can be done. But
why have bad data in the first place, starting with rubbish and then
proving that it can be cleaned up a bit using clever software?

The effort will make the engineer look good, sure, but there will always be
collateral damage as errors propagate before they are fixed. The engineer's
eyes are not typically on the content, but on their software. The content
their bots and programs manipulate at times seems almost incidental,
something for "others" to worry about – "others" who don't necessarily
exist in sufficient numbers to ensure quality.

In short, my feeling is that the engineering enthusiasm and expertise
applied to Wikidata aren't balanced by a similar level of commitment to
scholarship in generating the data, and getting them right first time.

We've seen where that approach can lead with Wikipedia. Wikipedia hoaxes
and falsehoods find their way into the blogosphere, the media, even the
academic literature. The stakes with Wikidata are potentially much higher,
because I fear errors in Wikidata stand a good chance of being massively
propagated by Google's present and future automated information delivery
mechanisms, which are completely opaque. Most internet users aren't even
aware to what extent the Google Knowledge Graph relies on anonymously
compiled, crowdsourced data; they will just assume that if Google says it,
it must be true.

In addition to honest mistakes, transcription errors, outdated info etc.,
the whole thing is a propagandist's wet dream. Anonymous accounts!
Guaranteed identity protection! Plausible deniability! No legal liability!
Automated import and dissemination without human oversight! Massive impact
on public opinion![3]

If information is power, then this provides the best chance of a power grab
humanity has seen since the invention of the newspaper. In the media
landscape, you at least have right-wing, centrist and left-wing
publications each presenting their version of the truth, and you know who's
publishing what and what agenda they follow. You can pick and choose,
compare and contrast, read between the lines. We won't have that online.
Wikimedia-fuelled search engines like Google and Bing dominate the
information supply.

The right to enjoy a pluralist media landscape, populated by players who
are accountable to the public, was hard won in centuries past. Some
countries still don't enjoy that luxury today. Are we now blithely giving
it away, in the name of progress, and for the greater glory of technocrats?

I don't trust the way this is going. I see a distinct possibility that
we'll end up with false information in Wikidata (or, rather, the Google
Knowledge Graph) being used to "correct" accurate information in other
sources, just because the Google/Wikidata content is ubiquitous. If you
build circular referencing loops fuelled by spurious data, you don't
provide access to knowledge, you destroy it. A lie told often enough etc.

To quote Heather Ford and Mark Graham, "We know that the engineers and
developers, volunteers and passionate technologists are often trying to do
their best in difficult circumstances. But there need to be better attempts
by people working on these platforms to explain how decisions are made
about what is represented. These may just look like unimportant lines of
code in some system somewhere, but they have a very real impact on the
identities and futures of people who are often far removed from the
conversations happening among engineers."

I agree with that. The "what" should be more important than the "how", and
at present it doesn't seem to be.

It's well worth thinking about, and having a debate about what can be done
to prevent the worst from happening.

In particular, I would like to see the decision to publish Wikidata under a
CC0 licence revisited. The public should know where the data it gets comes
from; that's a basic issue of transparency.
