Hi,
I just published the 2020 report on Wikidata Property constraints, the
results of an analysis carried out thanks to a Rapid grant from the
Wikimedia Foundation.
https://www.wikidata.org/wiki/Wikidata:2020_report_on_Property_constraints
You can take a look at the report and complement it with your comments
and suggestions to improve the system of Property constraints on the
talk page.
https://www.wikidata.org/wiki/Wikidata_talk:2020_report_on_Property_constra…
Although the scope is limited, I hope you find the content useful.
Thanks to the Wikimedia Foundation, to Wikimedia Deutschland, to the 58
active editors who completed the survey I sent them in December and to
all those who dedicate their time and effort to improving the quality of
Wikidata data.
Regards,
David

Hello all,
While cleaning (reviewing and rewriting) the code of Wikidata and Wikimedia
Commons backend in October 2019, The Wikidata team at WMDE together with
WMF worked on reducing the loading time of pages. We managed to reduce the
loading time of every Wikidata page by about 0.1-0.2 seconds. This is due
to a reduction of the modules (sets of code responsible for a certain
function) that need to be loaded every time a page is opened by someone.
Instead of 260 modules, which needed to be loaded before, only 85 modules
need to be loaded now when the page is called. By doing so, it is easier to
load Wikidata pages for people who only have a slow internet connection.
Link to picture on Commons:
https://commons.wikimedia.org/wiki/File:Reduced_loading_times_cut.png
Description: Size decrease of the initialization loader on Wikidata pages (see
on Grafana
<https://grafana.wikimedia.org/d/BvWJlaDWk/startup-manifest-size?orgId=1&fro…>
)
Reducing the amount of modules called when loading the page equals a
reduction of about 130 GB of network traffic for all users every day, or
47TB per year. The reduction of network traffic translates into a reduction
of electricity use, thus, this change is also good for the environment.
Additionally, the interdependencies between the modules were reduced from
4MB to 1MB, which improved the loading time per page as well.
Many thanks to everyone involved in this improvement! If you want to get
more details about the actions we performed, you can have a look at the
Phabricator board
<https://phabricator.wikimedia.org/project/board/4268/query/all/>.
If you are developing scripts or tools on top of the Wikidata UI, some
documentation will walk you through the architecture of RessourceLoader
<https://www.mediawiki.org/wiki/ResourceLoader/Architecture>, what’s page
load performance
<https://www.mediawiki.org/wiki/Wikimedia_Performance_Team/Page_load_perform…>
and how to create module bundles with ResourceLoader
<https://www.mediawiki.org/wiki/ResourceLoader/Developing_with_ResourceLoader>.

Hello folks,
We would like to invite you to apply to the Outreachy and Google Summer of
Code program with the Wikimedia Foundation (a non-profit organization
behind Wikipedia)!
*About the Outreachy program*
Wikimedia will be mentoring ~7 projects in the Outreachy program in the May
to August 2020 round. The initial applications are due February 25th at 4
pm UTC.
Apply today: https://www.outreachy.org/apply/
Outreachy offers three-month internships to work remotely in Free and Open
Source Software (FOSS) projects with experienced mentors. The internships
may include programming, user experience, documentation, illustration and
graphic design, or data science.
Outreachy internships run twice a year – from May to August and December to
March. Interns are paid a stipend of $5,500 USD for the three months of
work. They also have a $500 USD stipend to travel to conferences and
events. Interns often find employment after their internship with Outreachy
sponsors or in jobs that use the skills they learned during their
internship.
Outreachy is open to both students and non-students. Outreachy expressly
invites the following people to apply:
* Women (both cis and trans), trans men, and genderqueer people.
* Anyone who faces under-representation, systematic bias, or discrimination
in the technology industry in their country or residence is invited to
apply.
* Residents and nationals of the United States of any gender who are
Black/African American, Hispanic/Latin@, Native American/American Indian,
Alaska Native, Native Hawaiian, or Pacific Islander.
*About the Google Summer of Code program*
Wikimedia is planning to mentor 8-10 projects in 2020’s Google Summer of
Code (GSoC) program. Beginning February 20th, pending Wikimedia’s
acceptance as a mentoring organization, applicants can begin discussing
ideas with the mentors!
The student application will be due on March 31st 18:00 UTC:
https://summerofcode.withgoogle.com/
Google Summer of Code now in its 16th year, is Google's summer program for
university students who want to get involved in open source software. Over
15,960 students from 109 countries have already participated. Google Summer
of Code is a unique program that pairs students with mentors who introduce
them to the open-source community and provide guidance while they work on
real-world open-source projects during their summer break from university.
Projects cover a wide range of fields including: Cloud, Operating Systems,
Graphics, Medicine, Programming Languages, Robotics, Science, Security and
many more. It's a highly competitive program (and this year is expected to
be even bigger than last year), so don't wait until the last minute to
prepare!

Hi all,
Just a reminder that OpenRefine needs your feedback to decide how it
should evolve in the coming years. We have a very short survey that you
can take to let us know what you think:
https://docs.google.com/forms/d/e/1FAIpQLSd-Z00h433Y0pIutYyeW98C0Yss6p7RFis…
In the previous survey, run in 2018, the problem that people brought up
most often was the poor performance on large datasets. So that is what
we are working on improving this year. Your responses to this survey
will shape the future of the tool!
Thanks,
Antonin
Hello -
There's a list of the ShEx expressions created thus far:
https://www.wikidata.org/wiki/Special:AllPages?from=&to=&namespace=640
Is there any hope that wikibase could link direct to specific shex, so if
there is a shex for an item being used as a class, or if a wikibase item is
an instanceOf one of those classes, wikibase could link straight to the
shex?
Similarly, if there's an item that is being used as a class, could there be
an automatic link that shows instances of that class? This isn't too hard
to quick copy some item numbers and write a query to do, but it'd be a
nicer experience to just click on a link right on the page for a class to
see examples of that class.
Ultimately it'd be super-cool if you could create a new item as an
instanceOf a class direct from a class page like the Cradle tool (
https://tools.wmflabs.org/wikidata-todo/cradle/#/ ) for anything.
Thanks for everything that you've been working on with wikibase/wikidata!

1. Call for Papers - Ph.D. Symposium
*******************************************
The ESWC 2020 Ph.D. Symposium is a forum for Ph.D. students working in all areas of Semantic Web research to present their work, meet with peers and experienced researchers, receive feedback, and learn from each other’s experiences. It aims at helping Ph.D. students in developing the skills and confidence required to conduct and promote their research, as well as providing them with an opportunity to attend one of the most important research conferences on the Semantic Web.
The ESWC Ph.D. Symposium will give students the opportunity to:
* Learn by constructive criticism: Established researchers and Ph.D. student advisors will provide constructive feedback to the submitted papers by means of an open and non-adversarial review process.
* Learn from a mentor: Each student of an accepted paper will be assigned to a mentor- a selected member of the programme committee. Students will interact with their mentors on both the revision of their papers and the preparation of their presentations.
* Learn about research: Doing good research goes beyond writing a good paper; it includes perspectives on research as an endeavour and a career. Besides the presentations, coffee breaks and the Ph.D. mentoring lunch will be used to exchange ideas and ask questions about all aspects of pursuing a Ph.D. and a research career in general.
* Learn by presenting: Accepted contributions will be presented at the Ph.D. Symposium. All accepted contributions will also be included at the general poster session of ESWC. Students’ posters will be presented alongside posters and demonstrations of the main conference.

3. Call for Papers - Industry Track
*******************************************
The industry track seeks to present the state of adoption of semantic technologies in industrial applications, and intends to facilitate a discussion about what current industry challenges can be addressed with semantic technologies. These technologies may be used in specific industries (e.g., media, financials, telecommunications, healthcare, life sciences, government, intelligence, public sector, industrial production etc.) and in different application areas (e.g., business intelligence, smart cities, digital twin, analytics, search, content management, knowledge management, recommendation systems, data integration, automotive etc.).
The industry track aims to facilitate the exchange between Semantic Web researchers and industrial solution developers to bridge between state-of-the-art research and its application in industrial scenarios. We welcome contributions about:
* Success stories of adoption of semantic technologies and knowledge graphs in real-world environments, especially by emphasizing how these technologies have succeeded in creating value as well as key factors for the success of the adoption in a large-scale organization.
* Experiences about challenges that are encountered in an industry setting when adopting a solution based on semantic technologies.
* Contributions about current challenges in industrial fields which should be tackled by semantic technologies, emphasizing solution approaches and existing issues that are currently only insufficiently addressed by Semantic Web research.
Topics of interest include, but are not limited to, the following:
* Development and application of semantic technologies and knowledge graphs for specific industries (automotive, financial, healthcare and life sciences, energy industry, industry 4.0, public sector etc.)
* Real-world applications of semantic technologies for enabling FAIR (meta) data
* Approaches to bridge between domain experts and semantic technology experts
* Successful application domains: Knowledge management, data integration, data sharing, search, Business Intelligence, data analytics, open data, enterprise data management etc.
* Industrial trends related to the usage of Linked Data, Open Data and Semantic Web technologies
* Financial and strategic investments in semantic technologies
* Machine Learning approaches in connection with the Semantic Web (e.g. ML for knowledge graph completion or ontology matching, learning of knowledge graph and entity embeddings, question answering, etc)
