Re: [Wikidata] Code level documentation / reporting for Wikidata Query Service

Thanks Guillaume, I really appreciate it!

Reading them I've found that all the links in
https://doc.wikimedia.org/wikidata-query-rdf/parent/ are pointing to
https://doc.wikimedia.org/index.html currently a 404.

Thanks,

Alessio

[Wikidata] GlobalFactSync

2018-01-15 Thread Magnus Knuth 
Dear all,

last year, we applied for a Wikimedia grant to feed qualified data from 
Wikipedia infoboxes (i.e. missing statements with references) via the DBpedia 
software into Wikidata. The evaluation was already quite good, but some parts 
were still missing and we would like to ask for your help and feedback for the 
next round. The new application is here: 
https://meta.wikimedia.org/wiki/Grants:Project/DBpedia/GlobalFactSync

The main purpose of the grant is:

- Wikipedia infoboxes are quite rich, are manually curated and have references. 
DBpedia is already extracting that data quite well (i.e. there is no other 
software that does it better). However, extracting references is not a priority 
on our agenda. They would be very useful to Wikidata, but there are no user 
requests for this from DBpedia users.

- DBpedia also has all the infos of all infoboxes of all Wikipedia editions 
(>10k pages), so we also know quite well, where Wikidata is used already and 
where information is available in Wikidata or one language version and missing 
in another.

- side-goal: bring the Wikidata, Wikipedia and DBpedia communities closer 
together

Here is a diff between the old an new proposal:

- extraction of infobox references will still be a goal of the reworked proposal

- we have been working on the fusion and data comparison engine (the part of 
the budget that came from us) for a while now and there are first results:

6823 birthDate_gain_wiki.nt
3549 deathDate_gain_wiki.nt
  362541 populationTotal_gain_wiki.nt
  372913 total

We only took three properties for now and showed the gain where no Wikidata 
statement was available. birthDate/deathDate is already quite good. Details 
here: 
https://drive.google.com/file/d/1j5GojhzFJxLYTXerLJYz3Ih-K6UtpnG_/view?usp=sharing

Our plan here is to map all Wikidata properties to the DBpedia Ontology and 
then have the info to compare coverage of Wikidata with all infoboxes across 
languages.

- we will remove the text extraction part from the old proposal (which is here 
for you reference: 
https://meta.wikimedia.org/wiki/Grants:Project/DBpedia/CrossWikiFact). This 
will still be a focus during our work in 2018, together with Diffbot and the 
new DBpedia NLP department, but we think that it distracted from the core of 
the proposal. Results from the Wikipedia article text extraction can be added 
later once they are available and discussed separately.

- We proposed to make an extra website that helps to synchronize all Wikipedias 
and Wikidata with DBpedia as its backend. While the external website is not an 
ideal solution, we are lacking alternatives. The Primary Sources Tool is mainly 
for importing data into Wikidata, not so much synchronization. The MediaWiki 
instances of the Wikipedias do not seem to have any good interfaces to provide 
suggestions and pinpoint missing info. Especially to this part, we would like 
to ask for your help and suggestions, either per mail to the list or on the 
talk page: 
https://meta.wikimedia.org/wiki/Grants_talk:Project/DBpedia/GlobalFactSync

We are looking forward to a fruitful collaboration with you and we thank you 
for your feedback!

All the best
Magnus

Re: [Wikidata] GraFa: Faceted browser for RDF/Wikidata [feedback requested]

2018-01-15 Thread Aidan Hogan 

Hi all!

Just a friendly reminder that tomorrow we will close the questionnaire 
so if you have a few minutes to help us out (or are just curious to see 
our faceted search system) please see the links and instructions below.


And many thanks to those who have already provided feedback! :)

Best,
José & Aidan

Hey all,

A Masters student of mine (José Moreno in CC) has been working on a 
faceted navigation system for (large-scale) RDF datasets called "GraFa".


The system is available here loaded with a recent version of Wikidata:

http://grafa.dcc.uchile.cl/

Hopefully it is more or less self-explanatory for the moment. :)


If you have a moment to spare, we would hugely appreciate it if you 
could interact with the system for a few minutes and then answer a quick 
questionnaire that should only take a couple more minutes:


https://goo.gl/forms/h07qzn0aNGsRB6ny1

Just for the moment while the questionnaire is open, we would kindly 
request to send feedback to us personally (off-list) to not affect 
others' responses. We will leave the questionnaire open for a week until 
January 16th, 17:00 GMT. After that time of course we would be happy to 
discuss anything you might be interested in on the list. :)


After completing the questionnaire, please also feel free to visit or 
list something you noticed on the Issue Tracker:


https://github.com/joseignm/GraFa/issues


Many thanks,
Aidan and José
