Hoi,
I happen to work on Dukes of Friuli. Compare the data from Wikidata and the information by Reasonator based on the same item for one of them.
https://tools.wmflabs.org/reasonator/?&q=2471519 https://www.wikidata.org/wiki/Q2471519
Wikidata is not informative, you have to work hard to get the information that Reasonator provides already for over a year. All kinds of additional services can easily be added like the QR code and the family tree. The Reasonator info can be easily seen in any language, just add the labels. Thanks, GerardM

Hoi Gerard,
What I hear in email from Andreas and Liam is not as much the propagation of the error (which I am sure happens with some % of the cases), but the fact that the original source is obscured and therefore it is hard to identify and correct errors, biases, etc. Because if the source of error is obscured, that error is that much harder to find and to correct. In fact, we see this even on Wikipedia articles today (wrong dates of births sourced from publications that don't do enough fact checking is something I came across personally). It is a powerful and important principle on Wikipedia, but with content re-use it gets lost. Public domain/CC0 in combination with AI lands our content for slicing and dicing and re-arranging by others, making it something entirely new, but also detached from our process of validation and verification. I am curious to hear if people think it is a problem. It definitely worries me.
We have been looking very closely at Wikidata and the possibilities it offers. I am curious to understand more about your note on Resonator:
"As long as Wikidata does not have the power of a Reasonator, the data is just that. It does not make itself in information and consequently it is awful. When there is one thing the Wikidata engineers do not do, it is considering the use of the data and the workflows to improve the data and the quality."
Am I understanding you saying that until the data sees the light of day it will not become of high quality?
Thanks, Lila

Hoi, When a benefit is "Wikimedia specific" and thereby dismissed, you miss
much
of what is going on. Exactly because of this link most items are well defined as to what they are about. It is not perfect but it is good. Consequently Wikidata is able to link Wikipedia in any language to
sources
external to Wikipedia. This is a big improvement over linking external sources to a Wikipedia. The disambiguation of subjects is done at the Wikidata end.
You make Wikidata to be a "default reference source". Given its current state, it is a bit much. Wikidata does not have the maturity to function
as
such. The best pointer to this fact is that 50% of all items has two or fewer statements.
When you compare the quality of Wikipedias with what en.wp used to be you are comparing apples and oranges. The Myanmar Wikipedia is better
informed
on Myanmar than en.wp etc.
When you qualify a Wikipedia as fascist, it does not follow that the data is suspect. Certainly when data in a source that you so easily dismiss is typically the same, there is not much meaning in what you say from a Wikidata point of view.
I am thrilled that sources are so important to the Wikimedia movement and again, I am wondering what you hope to achieve by this pronouncement. Be realistic what is it that you want to achieve? Is quality important to
you
and, how do you define it and more importantly how do you want to achieve it. Have you seen the statistics on sources [1]? Then have a better look and you will find that real sources are mostly absent. Adding sources one statement at a time will not significantly improve quality because that
is
a numbers game and it is easier to achieve quality in a different way.
When a librarian says that many sources copy each others data and that
this
is a problem, the bigger problem is missed. The bigger problem is not
where
they agree but where they disagree. Arguably they are the statements
where
quality is more likely an issue. Now ask your librarian what is likely to improve Wikidata more either find Sources for the statements that differ
of
find Sources where the statements agree. Wikidata is not authoritative
but
when our community starts researching such issues both Wikidata and other sources will improve rapidly their quality. This is not to say that in
the
end you want both Sources where sources agree and disagree.
Then ask your librarian if there is a problem with missing data We can import data from sources and consequently be more informative or we do
not
import more data and people have to magically combine information that exists in many sources to get a composite view. We could see Wikidata as
a
place where data is combined and compared with other sources, Do tell
your
librarian that the process mentioned above should be iterative and it
will
be easily understood that comparing with just one additional source will improve the focus on likely issues even more.
PS What does your librarian think when she knows that the Dutch National Library is inclined to provide us with software so that books can be ordered at Dutch libraries from Wikidata data (and by inference from Wikipedias)?
When some see Wikidata as a source of reference, they will increasingly
be
served a better product. At this moment it is not good at all.
When German Wikimedians have concerns about quality.WONDERFUL but what
have
they done to improve things? Do they apply Wikipedia standards and how
does
that help?
You wonder why have "bad" data in the first place... Our data IS bad and there is not enough of it for it to be really useful. We can easily add more data and have a more useful result We can easily compare sources and ask people to concentrate on differences. However you can not tell me to add Sources to the data that I add. I will tell you to do it yourself. I
am
happy to improve on quality but on my terms, not yours.
You mention the propagation of errors.. How would that work. You indicate that there are not enough people to fix all the issues. With bots like Kian, we have probability in adding data. We have people add data where
the
software is not certain. You doubt technology but you do not know where
we
are, what is already done.
In short my feeling is that you do not know what you are talking about. There is real scholarship in the approach that I described, My take is in applying set theory. Kian is AI. For all I care yours is FUD.
Your notion of accountability is one of a consumer, it is not the accountability needed for a project that is immature and is not at all
at a
stage where you should imply that it is good enough and that quality is assured. There are domains in Wikidata that I will not touch because in
my
opinion it is wrong in its principles. At the same time I know that it
can
be fixed in time and leave it at that,
I disagree with Heather Ford and Mark Graham. As long as Wikidata does
not
have the power of a Reasonator, the data is just that. It does not make itself in information and consequently it is awful. When there is one
thing
the Wikidata engineers do not do, it is considering the use of the data
and
the workflows to improve the data and the quality.
The data needs to be CC-0 because it is how we ensure that everybody will be happy and willing to participate. As more participation happens as
more
collaboration occurs we will see Wikidata increase in the amount of data that it holds and at the same time we will see quality improve.
Yes, Wikidata could do more in the way of adding sources to data. As long as the "primary sources tool" does not add the sources it knows, what do you expect from anybody else. Thanks, GerardM

Hoi, To start of, results from the past are no indications of results in
the
future. It is the disclaimer insurance companies have to state in all
their
adverts in the Netherlands. When you continue and make it a
"theological"
issue, you lose me because I am not of this faith, far from it.
Wikidata
is
its own project and it is utterly dissimilar from Wikipedia.To start
of
Wikidata has been a certified success from the start. The improvement
it
brought by bringing all interwiki links together is enormous.That
alone
should be a pointer that Wikipedia think is not realistic.
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.
To continue, people have been importing data into Wikidata from the
start.
They are the statements you know and, it was possible to import them
from
Wikipedia because of these interwiki links. So when you call for
sources,
it is fairly save to assume that those imports are supported by the
quality
of the statements of the Wikipedias
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?
and if anything, that is also where they typically fail because many assumptions at Wikipedia are plain
wrong
at Wikidata. For instance a listed building is not the organisation
the
building is known for. At Wikidata they each need their own item and associated statements.
Wikidata is already a success for other reasons. VIAF no longer links
to
Wikipedia but to Wikidata. The biggest benefit of this move is for
people
who are not interested in English. Because of this change VIAF links through Wikidata to all Wikipedias not only en.wp. Consequently
people
may
find through VIAF Wikipedia articles in their own language through
their
library systems.
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.
So do not forget about Wikipedia and the lessons learned. These
lessons
are
important to Wikipedia. However, they do not necessarily apply to
Wikidata
particularly when you approach Wikidata as an opportunity to do
things
in a
different way. Set theory, a branch of mathematics, is exactly what
we
need. When we have data at Wikidata of a given quality.. eg 90% and
we
have
data at another source with a given quality eg 90%, we can compare
the
two
and find a subset where the two sources do not match. When we curate
the
differences, it is highly likely that we improve quality at Wikidata
or
at
the other source.
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.
