Hello,
When we issue queries using the MWAPI [1] programatically, we sometimes get a 500 error. I would guess that happens in more than 30% of the cases. The following SPARQL query causes the error:
SELECT DISTINCT *
WHERE {
SERVICE wikibase:mwapi {
bd:serviceParam wikibase:api "EntitySearch" .
bd:serviceParam wikibase:endpoint "www.wikidata.org<http://www.wikidata.org/>" .
bd:serviceParam wikibase:limit "once" .
bd:serviceParam mwapi:search "integre" .
bd:serviceParam mwapi:language "en" .
?subj wikibase:apiOutputItem mwapi:item .
}
}
LIMIT 2000
When calling the SPARQL endpoint from e.g. Python (sparqlwrapper) or Java (rdf4j), I sometimes get the following stack trace:
SPARQL-QUERY: queryStr=
SELECT DISTINCT *
WHERE {
SERVICE wikibase:mwapi {
bd:serviceParam wikibase:api "EntitySearch" .
bd:serviceParam wikibase:endpoint "www.wikidata.org<http://www.wikidata.org/>" .
bd:serviceParam wikibase:limit "once" .
bd:serviceParam mwapi:search "integre" .
bd:serviceParam mwapi:language "en" .
?subj wikibase:apiOutputItem mwapi:item .
}
}
LIMIT 2000

I use the following Python script to call the service, I assume http maybe also works:
from SPARQLWrapper import SPARQLWrapper, JSON
queryString = """
SELECT DISTINCT *
WHERE {
SERVICE wikibase:mwapi {
bd:serviceParam wikibase:api "EntitySearch" .
bd:serviceParam wikibase:endpoint "www.wikidata.org<http://www.wikidata.org/>" .
bd:serviceParam wikibase:limit "once" .
bd:serviceParam mwapi:search "integre" .
bd:serviceParam mwapi:language "en" .
?subj wikibase:apiOutputItem mwapi:item .
}
}
LIMIT 2000
"""
sparql = SPARQLWrapper("https://query.wikidata.org/sparql", returnFormat=JSON)
sparql.setQuery(queryString)
results = sparql.query().convert()
print(results)
Can we do something about this? Why does it throw a "java.util.concurrent.TimeoutException" on your side? Thank you very much for this service, it is very useful for us.
Best,

Hello all,
The development team is currently working on one of the projects of our 2020
roadmap <https://www.wikidata.org/wiki/Wikidata:Development_plan> called
"automated finding of references based on semantic markup". Our goal is to
analyze a bunch of structured data websites, compare the content to
Wikidata, and *suggest new references for unreferenced statements to the
editors*.
We now have the first batch of potential new references for you to look at
and give feedback on. Based on your feedback we will continue fine-tuning
and expanding the system.
Feel free to have a look and give feedback on this page
<https://www.wikidata.org/wiki/Wikidata:Automated_finding_references_input>.
Thanks,

ESWC 2020 will be a virtual conference between the original dates of May 31 and June 4.
While we still work out the details, the following is the high-level structure:
- The main paper tracks (research, resources and in-use tracks) will be run in an asynchronous fashion, with screencasts from the authors and an online forum for questions and discussions via the website.
- We go ahead with the original schedule for the proceedings of the main paper tracks; authors have to register by the end of April.
- The updated registration fees will be in-line with other virtual conferences.
- The satellite events (workshops, tutorials, posters, demos, the doctoral consortium and the industrial track) will be run in a synchronous fashion, supported by chat and bidirectional audio and video.
- We go ahead with the original schedule for the satellite contributions as post-proceedings.
- Because we are optimists, we plan a small optional post-conference symposium in Heraklion in the first half of October if the travel restrictions permit.
Please plan accordingly. We will provide updates via:
- the website - https://2020.eswc-conferences.org/
- Twitter - https://twitter.com/eswc_conf

Hello all,
The next Wikidata & Wikibase office hour will take place on Tuesday, April
7th at 18:00 (Berlin time, UTC+2), on the Wikidata Telegram channel
<https://t.me/joinchat/AZriqUj5UagVMHXYzfZFvA>.
As usual, we will present what happened from the development side in the
past three months, what's coming next, and you will have plenty of time to
ask questions.
See you there!
Cheers,

(usual apologies for cross-posting!)
The board of the Wikipedia & Education User Group invites you to attend our
user group's next Open Meeting, one week from today, on Thursday, April 2,
at 15:00 UTC, as always via Zoom. We'll be discussing the Wikimedia &
Education community's response to the COVID-19 pandemic. Guest speakers
include:
* Nichole Saad and Melissa Guadalupe Huertas from the WMF Education Team
will talk about their strategy and how you can help. (
https://lists.wikimedia.org/pipermail/education/2020-March/002511.html)
* User:TiagoLubiana, a graduate student in Computational Biology from the
University of São Paulo, and a leading editor at Wikidata:WikiProject
COVID-19, will discuss Wikidata's work around COVID-19 and how the
Wikimedia and education community can help. (
https://www.wikidata.org/wiki/Wikidata:WikiProject_COVID-19)
Per usual, the board will provide an update on user group activities, and
we'll offer an opportunity for others to briefly share what they've been up
to in light of the COVID-19 pandemic. Join us!
