[Wikidata] deprecated value search

2024-01-26 Thread Olaf Simons
Dear all,

Wikidata cities in the Ukrainian Odesa Oblast have a specialty:

https://www.wikidata.org/wiki/Q805554

the KOATUU ID is given as deprecated value (since these numbers were only valid 
until 2020).

What is the SPARQL search that gets these deprecated IDs?

much obliged,
Olaf

[Wikidata] age distribution

2021-11-10 Thread Olaf Simons
Dear all,

the following search gives you a list of members (of the Strict Observance) 
with their respective birth years.

https://tinyurl.com/yj87vvhp

I was trying to give an age profile of this group at a certain moment in time 
(1780) but my script changes failed.

This is something I can do by adapting a nice WD-query (Age of all human beings 
on FactGrid, age of death):

https://tinyurl.com/yhzquxwf

But my attempt to use a date instead of the age at death failed

https://tinyurl.com/yzc75fzv

...I have a vague idea why the replacement does not work that way, but no idea 
what the proper query would look like.

Best wishes,
Olaf

computation...)

Dear all,

thank you, Dragan for the answer, yet this is nothing I can explain to "normal 
users". They use the Query Service with the recommended input help and they do 
get inexplicable January 1st dates (which, if the are not suspicious, they will 
accept as the new knowledge).

What would speak against a a Query helper that gives data pretty much as we 
have entered them?

[Wikidata] SPARQL and January 1 dates

2021-06-23 Thread Olaf Simons
Dear All,

I wonder whether there is a simple way to retrieve dates with the precision in 
they have been put into a wikibase.

Using SPARQL I get all years such as "1749" as "1 January 1749" statements, no 
matter whether the person is born that day or not. Should I run different 
searches?

Olaf

  ?s p:P266 ?st. # ?s is the the statement node
  ?st ps:P266 ?o. # that simulates the predicate
  ?st ?qualifier ?value. # this is an attribute (a qualifier)

as scripted by Marie Destandau - the values needed some tedious transformation

[Wikidata] Gregorian/Julian dates QuickStatements

Dear Wikidata people,

I am trying to find out whether QuickStatements has found a way to define 
Julian/Gregorian markers on dates.

We have massive lists of dates for German and English territories after 1582 
that are on the Julian calendar since they come from Protestant or Eastern 
Orthodox calendars that switch to Gregorian far later. Is there a way to mark 
the proper calendar on a QuickStatement input - which we could easily do with a 
look at our varius sources.

Re: [Wikidata] a question of data modeling about family ties

2020-10-05 Thread Olaf Simons
Dear Wikidata list,

one of our big contributors, Bruno Belhoste in Paris, just gave me a weird 
question which I feel I cannot answer that fast.

We, FactGrid, are a Wikidata child and so it came that we adopted structures 
like the father/mother differentiation. Bruno's question is now whether it 
would not have been wise to just create just a "parent" option instead of the 
gender fork that splits the lineages. Let me insert his mail:


> Dear Olaf,

I wonder what people with more data knowledge think about the proposal (which 
would affect just our site, not Wikidata...) (so: no worries, we can do 
experimental things without affecting our parent - I hesitate to speak of a 
father or mother - Wikidata).

Best,
Olaf

[Wikidata] Quickstatements to put labels on Properties

2020-05-04 Thread Olaf Simons
Hi Wikidata people,

I am trying to use QuickStatements in order to set Spanish Labels and 
Descriptions on all the Properties of our Wikibase (FactGrid). E.g.:

P367Les "Identificación de la BnF"

Somehow I fail with the error code "Revision with ID not found". I can, however 
easily set these alternative statements (Q24 is the sandbox item):

Q24 Les "Identificación de la BnF"
P367P2  "Identificación de la BnF"

There seems to be a particular thing to observe about Property labels and 
descriptions - any clue?

Cheers,
Olaf

[Wikidata] SPARQL query

2020-03-05 Thread Olaf Simons
Dear list,

I was trying to run a Sample query from Wikidata on our page but I do not get 
the result I was hoping for. Can anybody give me an idea what I am doing wrong?

This is Wikidata's original Script:

https://query.wikidata.org/#%23Content%20of%20a%20reference%20for%20a%20specific%20statement%0A%23%20See%20also%20the%20SPARQL%20manual%0A%23%20https%3A%2F%2Fen.wikibooks.org%2Fwiki%2FSPARQL%2FWIKIDATA_Qualifiers%2C_References_and_Ranks%0A%23%20In%20this%20example%20we%20look%20for%20statements%20which%20assign%20a%20specific%20value%20%28Q51955019%29%0A%23%20to%20the%20property%20P1343%20and%20then%20look%20for%20references%20of%20that%20property%2C%20specifically%0A%23%20the%20string%20associated%20to%20P958%20for%20the%20reference.%20May%20actually%20bring%20up%20references%0A%23%20for%20other%20P1343%20statements%3B%20uses%20the%20shortened%20expression%20syntax%20with%20brackets.%0ASELECT%20%3Fitem%20%3Freference%0AWHERE%20%7B%0A%20%20%3Fitem%20wdt%3AP1343%20wd%3AQ51955019%20.%0A%20%20%3Fitem%20p%3AP1343%20%5B%20prov%3AwasDerivedFrom%20%5B%20pr%3AP958%20%3Freference%20%5D%20%5D%20.%0A%7D


this is my adaptation for FactGrid:

https://database.factgrid.de/query/#%23Content%20of%20a%20reference%20for%20a%20specific%20statement%0A%23%20See%20also%20the%20SPARQL%20manual%0A%23%20https%3A%2F%2Fen.wikibooks.org%2Fwiki%2FSPARQL%2FWIKIDATA_Qualifiers%2C_References_and_Ranks%0A%23%20In%20this%20example%20we%20look%20for%20statements%20which%20assign%20a%20specific%20value%20%28Q38779%29%0A%23%20to%20the%20property%20P91%20and%20then%20look%20for%20references%20of%20that%20property%2C%20specifically%0A%23%20the%20string%20associated%20to%20P51%20for%20the%20reference.%20May%20actually%20bring%20up%20references%0A%23%20for%20other%20P1343%20statements%3B%20uses%20the%20shortened%20expression%20syntax%20with%20brackets.%0ASELECT%20%3Fitem%20%3Freference%20%3FreferenceLabel%0AWHERE%20%7B%0A%20%20%3Fitem%20wdt%3AP91%20wd%3AQ38779%20.%0A%20%20%3Fitem%20p%3AP91%20%5B%20prov%3AwasDerivedFrom%20%5B%20pr%3AP51%20%3Freference%20%5D%20%5D%20.%0A%7D


and this is a FactGrid Item where this should work:

https://database.factgrid.de/wiki/Item:Q969

the man is proposed for an Illuminati Membership P91+Q38779. I want the query 
service to fetch the answer on the reference statement P51 primary source (and 
realise that my searches do not pay respect to the Q38779 focus). (Maybe the 
scripted focus does not even work on Wikidata...)

Thanks for the clue,

Olaf

and I gave a mutilated link again... This is my search:

now most of these places have a Wikidata reference, which you find in the 
section of Wikimedia-related projects (at the end or to the right, where you 
can link to Wikipedias).

https://database.factgrid.de/wiki/Item:Q10279

the Wikidata link is under "wikidatawiki"

I am wondering how I can have these Wikidata Q-numbers in a column. (I am just 
preparing a new input from Wikidata and want to make sure I do not create 
double records - identical Wikidata-numbers are the indicator that we already 
have the item...)

best,

no, not quite. My problem is that the wikidata number (that appears in the

[Wikidata] SPARQL query for wikdata no on external Wikibase

2020-01-22 Thread Olaf Simons
On FactGrid we have matched all our items with the respective Wikidata 
Q-numbers (wherever possible). Does anybody know what SPARQL query I should use 
to get these numbers?

This is a geographical entity on our wikibase with the Wikidata number at the 
appropriate place

https://database.factgrid.de/wiki/Item:Q89076

and this is the SPARQL-query to all geographical places which I would love to 
get with the respective Wikidata numbers

Best,

[Wikidata] Query Service break down on FactGrId

2019-11-14 Thread Olaf Simons
Dear list,

I am experiencing unexpected problems with running Queries on FactGrid. (You 
find some sample queries here: 
https://database.factgrid.de/wiki/FactGrid:Projects) The error code is:

Can anyone make more sense of the information and how to handle it?




502 Proxy Error

Proxy Error
The proxy server received an invalid
response from an upstream server.
The proxy server could not handle the request GET /sparql.
Reason: Error reading from remote server

Apache/2.4.25 (Debian) Server at database.factgrid.de Port 
443




If I have killed the application it was with an attempt to get given names with 
our (deprecated) string Property P88 - trying to get the names together with 
the respective P101 "place in sequence" qualifiers.

Please tell me that it is impossible to kill our SPARQL with flawed scripts for 
queries.

Cheers,
Olaf

[Wikidata] SPARQL- query: stretch in time

2019-10-07 Thread Olaf Simons
Dear List,

a colleague has asked me how she could generate a timeline with spans of time 
on the FactGrid wikibase. She wants to visualise to what extent Gotha's duke 
Ernest II was in Gotha - and to what extent he was actually elsewhere on 
journeys leaving it to his ministers to rule the country.

I made a test input with two properties on the Item for Ernest:

https://database.factgrid.de/wiki/Item:Q978

P316 is for journeys with beginning and end. P296 eill become more specific in 
order to generate itineraries.

I's be grateful for the SPARQL-Query that brought stretches of time for 
journeys on the timeline.

My thanks for any help,
Olaf

[Wikidata] a little thing someone might love to code

2019-09-23 Thread Olaf Simons
just wrote a little blog post on Paul-Olivier Dehaye's visualisation of the 
Illuminati correspondence - done from a SPARQL query of our wikibase:

https://blog.factgrid.de/archives/1695

an interface for this visualisation should not be too difficult to script - I'd 
have some ideas about the simple functionalities such a thing should have.

...if I can inspire someone.

Cheers
Olaf

Re: [Wikidata] Dead or alive ? Probably dead

2019-09-19 Thread Olaf Simons
On FactGrid we created two properties for this (maybe clever, maybe daft): P290 
and P291 for estimates (or for knowledge) of an earliest and latest point in 
the life span. The necessity is here that we have loads of people with just a 
single data point like "studied in Jena in 1776" or "appeared on a list of 
voters in 1849". If that is all you know, you do actually know that the person 
is likely to have a birth date some 17 (or in the voters case at least 21) 
years before.

If a person is only once mentioned as retired that stretches the P290 date to 
some 60 years before and so on - you qualify the estimate accordingly.

I have no idea whether this is a good move on our site since we are not really 
that advanced in running the more intriguing SPARQL searches.

[Wikidata] Tinyurls no longer operable

2019-09-11 Thread Olaf Simons
The use of tiny urls has changed over night - in a welcome move towards more 
independence. 

The problem for us (FactGrid, an external wikibase) is now that all the given 
links have stopped working. 

Is there an elegant way to fix this?

Best wishes,
Olaf

This might be then the central thing to have in the next QueryService Version: 
In addition to the present download formats an option to get a csv or tsv 
output that can be put into QuickStatements for another Wikibase without 
tedious conversions.

We will have more and more people with Wikibase installations who will use 
Wikidata (or other Wikibases) as data source for their platforms.

Maybe I can inspire Magnus...

Thank you Jan for the swift answer
(I wish I had known before this morning's first data input...)



allow me 2 follow-up questions:

Is there an elegant way to get data out of wikidata in a format that you can 
then fill back into another Wikibase without the pain of such conversions (like 
splitting coordinates, changing columns, changing the prefixes...)

Question 2 is related: When you extract dates with the QueryService that will 
change just years like 1971  from 1971-00-00 into 1971-01-01 dates. I felt 
unable to tell whether such a date was just a year or actually a January 1 
entry. Is there a way to get the exact date as it has been put in to Wikibase 
back from the QueryService?

All my thanks,
Olaf

[Wikidata] Wikidata geo-coordinates

I am trying to synchronise FactGrid data with Wikidata.

A strange question: If I run a SPARQL search such as this one:

https://query.wikidata.org/#SELECT%20%3FGemeinde_in_Deutschland%20%3FGemeinde_in_DeutschlandLabel%20%3Fgeographische_Koordinaten%20WHERE%20%7B%0A%20%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%0A%20%20%3FGemeinde_in_Deutschland%20wdt%3AP31%20wd%3AQ262166.%0A%20%20OPTIONAL%20%7B%20%3FGemeinde_in_Deutschland%20wdt%3AP625%20%3Fgeographische_Koordinaten.%20%7D%0A%7D

I get the coordinates with what looks like swapped values:

"Point(10.7183 50.9489)" on the QueryService table output
"50°56'56"N, 10°43'6"E" on P625 at the respective Wikidata Item Q6986 

any idea why this is so?

[Wikidata] remove alias via QickStatements

2019-08-22 Thread Olaf Simons
Dear Wikibase fans,

I was trying to remove aliasses with QuickStaements (on the FactGrid 
installation).

The specific removal seems to be impossible without more technical knowledge 
(if I read this correctly: 
https://bitbucket.org/magnusmanske/wikidata-todo/issues/114/quickstatements-allow-removal-of-alias)
 

Is there a way just to remove all the aliasses of a bulk of items?

QuickStatement Wikidata-Help says "If you want to remove a 
label/description/sitelink, the value has to be an empty string and the rest of 
the command will be the same." the word alias is not in this list - or I may 
not have understood what an empty string would look like.

Cheers,
Olaf

[Wikidata] sorting statements with quicksteps

2019-05-08 Thread Olaf Simons
Hi Wikidata people,

I am trying to organise a QuickStatement Input for churches and people who held 
offices in these churches - on our Wikibase. 


Using QuickStatements I get the problem when a person gets into a new 
position/qualification - as you can see here with "Friedrich Linde who was 
spends sone years as an assistant before he becomes a pastor:

https://database.factgrid.de/wiki/Item:Q43367

QuickStatements states all the positions and then all the years on different 
heaps - where I would love have the dates on the respective positions.

If I add the same man with a new position manually I get the trick done (but 
that is nothing I want to do with several thousand office terms).

May be my entire approach is stupid - any idea how I could sort this out better?

cheers,
Olaf

Re: [Wikidata] Wikibase as a decentralized perspective for Wikidata

2018-11-28 Thread Olaf Simons
What is more problematic than the p/q business:

If I run a SPARQL search at our endpoint - such as this one:

https://database.factgrid.de/query/#SELECT%20%3FIlluminatenorden%20%3FIlluminatenordenLabel%20WHERE%20%7B%0A%20%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%0A%20%20%3FIlluminatenorden%20wdt%3AP91%20wd%3AQ10677.%0A%7D

I will receive answers in the form of 

wd:q25 

but they do not lenk to wd, wikidata, but into our database 
https://database.factgrid.de/entity/Q25. 

The same problem in the other direction: If our users have never seen a SPARQL 
search in their lives (and that's 100%) and if they now click at sample queries 
- they will qet Wikidata sample queries which do not work on our database - 
just as our P and Q numbers do not match.

[Wikidata] Illuminati Data Mining, Gotha Nov. 16/17

2018-11-05 Thread Olaf Simons
Dear Wikidata list,

our Illuminati-budget is still not yet exhausted. Let me send out a second call 
for our workshop next week:

We are planning to use our upcoming yearly Illuminati-Workshop at the Gotha 
Research Centre to get a better idea of the database we have created in the 
past months at 

https://blog.factgrid.de/

We can offer grants for travel expenses (in central Europe) and accommodation 
in Gotha - and will give you insight into the present state of research into 
the real Illuminati, those of the 1770s and 1780s.

We are looking for creative ideas of what to do with our wikibase installation 
(you can see some sample queries here: 
https://database.factgrid.de/wiki/Sample_queries).

* How would we best connect our database to Wikidata?
* What intriguing visualizations could we offer?
* What searches would be possible?
* What should we do with our old media wiki 
(https://projekte.uni-erfurt.de/illuminaten/Main_Page)? - a site which is 
presently still far more valuable with its transcripts of and commentary on 
documents (we would love to migrate all its content into the new database).
* How would we organise a crowd sourced project on the new database?

The workshop will begin on Friday 16, 9:am with scholarly talks for those 
interested. We will open the data mining section in the early afternoon and 
give here an introduction into

* our database,
* our data and 
* the history and structures of the Order (which we would love to better 
explore with the database).

The data miners would have the ensuing afternoon and early evening and part of 
Saturday morning for exploration. We would eat out together and exchange views 
again on Saturday morning.

Here our German program with Google translation: 
https://blog.factgrid.de/archives/1151

Contact olaf.sim...@pierre-marteau.com during the next three days to make 
reservations.

Looking forward to the event,
Olaf

[Wikidata] Illuminati/ Wikibase Workshop

2018-10-21 Thread Olaf Simons
Dear Wikibase Enthusiasts,

if you happen to speak German and if you feel intrigued about the Illuminati, 
this might be of interest to you:

https://blog.factgrid.de/archives/1151

We will use our upcoming Illuminati-Workshop on Nov. 16/17 to discuss how we 
can make better use of our Wikibase installation here at Gotha.

https://database.factgrid.de/wiki/Main_Page

The database is filled with metadata of Illuminati documents and (selected) 
membership information and is supposed to help us with complexities of our 
Illuminati wiki (https://projekte.uni-erfurt.de/illuminaten/Main_Page), but we 
do not yet have the clearest idea of what we have produced here or possibly can.

If you feel intrigued - we pay travel expenses and accommodation - contact me 
before Nov. 5, 2018.

Looking forward to an illuminating workshop,
Olaf

[Wikidata] Membership information and SPARQL on FactGrid

2018-09-21 Thread Olaf Simons
Hi Wikidata people,

We have started to widen our collection of various historical people with 
various memberships on our wikibase installation - FactGrid, a "database for 
historians" (which should eventually become a source for Wikidata).

This is a typical dataset on a person: 
https://database.factgrid.de/wiki/Item:Q84
This one is more complex: https://database.factgrid.de/wiki/Item:Q1319

I am wondering whether it was clever to put the individual membership in a 
lodge (or several lodges) under a wider umbrella of "member of Freemasons". How 
for instance can we now ask our query service for a list of all Freemasons plus 
individual lodge affiliation.

Question: Is it good to create such subplots with qualifiers? Is it good to do 
this in the light of the SPARQL queries we want to run? Is it good with a 
perspective on the additions we could perhaps better add if we avoided such 
subclauses? - like dates of membership in different lodges? (That seems to be a 
problem right now...)

We have far more details of membership information (like functions in these 
societies) and I feel we can find very different arrangements like

* create qualifiers for a particular membership (member of the Illuminati plus 
50 qualifiers of details information...
* create minute and specialised properties for each sort of organisation which 
are then offered on one level (a property for membership in the Illuminati, 
particular property for the person who proposed the new member, a property for 
the date of entry, a property for the first grade, a new property for grade 2 
and so on... 
* create a branch of new items for membership information sorted by 
organisation - something like a membership card for any individual membership 
in any sort of association. A person who is member of the Illuminati would then 
get a new item for his particular membership with different entries on who 
brought him into the order? When accepted, when promoted to which level? where 
affiliated? What internal positions...

See this blog entry for details we have on any particular Illuminati 
membership: https://blog.factgrid.de/archives/47

What kind of mess would we create with membership-items in future SPARQL 
queries? I feel dizzy with these questions.  

How would you organise such things if you were aiming at a kind of animation, 
where we will eventually see how the Illuminati infiltrated lodges? 

These are peculiar questions. We could need some advice from people who can 
already foresee the SPARQL calamities we are creating with these first data 
sets - and the difficulties we are creating for Wikidata as a future user of 
our research data. So maybe you can help us with good advice on how to best 
organise our weird knowledge.

Best,
Olaf

Re: [Wikidata] Solve legal uncertainty of Wikidata

Works well in an environment of no original research. Things get onto another 
level if I have a fact that is of value in other fields of research. I can then 
either keep it for myself until it is published in a paper that will be quoted 
by Wikidata...

...or I need options to state the fact as "herewith published by me and to be 
quoted as my research..."

I am actually eager to get an environment in which I - as a researcher - can 
dare to open the box and to play with my research in the open environment.
