 It's also, for simialr reasons, easier for a human editor to add a
 Wikipedia link, but a script (or even the editing tool itself) could
 then do a lookup and subistite, or add, the Wikidata ID.

It isn't that easy to add Wikidata ID's with a script. Wikipedia
articles often describe more than one object. For example the article
of Heligoland: http://en.wikipedia.org/wiki/Heligoland

The article describes the island and the municipality. To model this
in Wikidata you need two different objects. For the island:
https://www.wikidata.org/wiki/Q17043877 and municipality:
https://www.wikidata.org/wiki/Q3038

I've tried to describe the issue here:

 It might be useful to give a couple of examples. We would link St
 Paul's Cathedral to :

 https://www.wikidata.org/wiki/Q173882

 That, in turn has links to the Wikipedia articles about the cathedral,
 in ~50 languages, 
cut

How do/would Wikidata links relate to Wikipedia links in OSM objects?

i.e. Does this suggest Wikidata links should supercede Wikipedia links or would 
they be complimentary?

Presumably if complimentary (to maintain existing data users' usage of 
Wikipedia tags) - one could write a test to confirm they are referencing the 
same thing to check consistency.

Strictly speaking, a Wikidata link makes links to Wikipedia redundant,
as the Wikidata item itself links to relevant Wikipedia pages.
Pragmatically, though, human editors (as opposed to machine parsers)
may prefer to see a Wikipedia link, in their own and or the local
language(s), as they have text labels in the language concerned.

It's also, for simialr reasons, easier for a human editor to add a

One could. It's the sort of thing a validator like that in JOSM might check.

That, in turn has links to the Wikipedia articles about the cathedral,

languages (Katedralo Sankta Paŭlo in Esperanto, or Ardeaglais Naomh
Pól in Gaelic not to mention names in languages with  non-Western
alphabets, like Japanese, Russian and Arabic). It links to an image;
and to the Wikimedia Commons category for hundreds more images. It
tells us that the building is made of Portland limestone, and in the
English Baroque architectural style (and links to Wikidata entities
for those terms, which similarly link to Wikipedia articles, and
more...). It includes links to entries in a number of other databases
and catalogues, ranging from VIAF to the Vatican library, and even
MusicBrainz (so we can get a list of recordings made there; and who
made them). And much more besides.

Even for a small church like St James, Handsworth (Birmingham), we have:

   https://www.wikidata.org/wiki/Q16908818

with Wikipedia links in two languages, the location of the church's
archives, the architect's name (again linking to a Wikidata entry and
thus Wikipedia biography), and the prospect of more data and links
being added with time.

All of this information is available, as open, linked data, via API
and RDF dumps, adding vast richness to our data in OSM, and providing
a great service to the re-users of our data.

How do we measure the success of any tag in OSM? Some thoughts:

   - Other users start to contribute using the same tag
   - Our data consumers start making use of the tag
   - The tag is given greater prominence in the main editors

This Saturday at SOTM-EU in Karlsruhe there will be a talk with a

If all goes well there will be a live stream as well as a recording
afterwards. No idea if that is a competitor or if both ideas can be

Hi Andy,

I like the idea, and it'd be great if some dabbling happened in
advance of wikimania. I'm not promising to get involved (sorry) since
not sure I'll have time.

But I have no idea how to do a structured search in wikipedia (i.e.
search for items within a category, which have co-ordinates). If you
know any way, or tutorials etc, then sharing those might help OSMers
to think about it?

I've added some quick findings about this, to the discussion:

Tom,

Measuring the success of a bot can be done in the same way that the success
is measured in a statistical model; Type I and Type II errors. So for
example, if the test is to attach wikidata tags to churches then:

* A type I error would be failing to add the wikidata to the associated
church (we can accept large errors in this case as it represents the
current no-bot situation)
* A type II error would be adding the wrong wikidata to a church. We need
to minimise these. I'll suggest a 1-2% error as this matches the general
quality of public data.

I unfortunately don't have the skills to help with editing, but support
initial trials as a good step to working more closely with wikimedia
commons.

Best,
Rob

success is measured in a statistical model; Type I and Type II errors. 
So for example, if the test is to attach wikidata tags to churches then:


Measured that way, I could code a bot that sets name=foo for all objects 
with a name tag. Assuming I'm decent at coding, I could have zero Type I 
and Type II errors, and by those criteria this mechanical edit would be 
a success.


Success should be measured against the reasons for the mechanical edit. 
Adding wikidata tags isn't the reason, it's what it does.

I was taking the question of accuracy as a given.

My point was not whether we can accurately add the right tags, but 
rather whether doing so is actually useful.


There's an almost infinite number of things we could add, but if nobody

Re: [Talk-GB] Adding links to Wikidata (and Wikipedia?)

2014-06-08 Thread Rob Nickerson
Paul, Tom

I interpreted measure of success to mean success of the bot process,
rather than usefulness of doing this in the first place. As with Andy I
took the usefulness as read. Wikidata is growing quickly but nobody can
argue that wikipedia is not an invaluable resource today. Anything we can
do to provide better links between OSM objects and Wikimedia Commons (be
that via wikipedia or wikidata) is a good thing IMHO.

Whether we use a bot to add wikipedia links or wikidata links depends on
whether you think wikidata continue to grow. To me wikidata makes a lot of
sense (as it is a data store and links to the wikipedia articles in all
languages), but I wouldn't complain if more wikipedia tags were added.

Rob

p.s.
name=foo to all objects would be a type 2 fail. In the wikidata example you
would want to add the wikidata reference to object foo only if name=foo
in OSM (and geographic location is correct). Your catch all would falsely
identify all objects in osm as foo and therefore apply the wikidata ref
to all objects - a clear fail!! (my explanation of type 2 errors wasn't
that good, but the wiki article gives a thorough explanation).
