The International Semantic Web Conference (ISWC) is the premier venue for
presenting fundamental research, innovative technology, and applications
concerning semantics, data, and the Web. It is the most important
international venue to discuss and present latest advances and applications
of the semantic Web, knowledge graphs, linked data, ontologies and
artificial intelligence (AI) on the Web.
ISWC attracts a large number of high quality submissions every year and
participants from both industry and academia. ISWC brings together
researchers from different areas, such as artificial intelligence,
databases, natural language processing, information systems, human computer
interaction, information retrieval, web science, etc., who investigate,
develop and use novel methods and technologies for accessing, interpreting
and using information on the Web in a more effective way.

Become part of ISWC 2019 by submitting to the following tracks & activities
or just attend them!
1. Call for Workshops
*******************************************
Besides the main technical program, ISWC will host several workshops on
topics related to the general theme of the conference. The role of the
workshops is to provide a setting for focused, intensive scientific
exchange among researchers and practitioners interested in a specific
topic. As such, workshops are the primary venues for the exploration of
emerging ideas as well as for the discussion of novel aspects of
established research topics.
We invite you to submit a proposal for workshops on a research topic of
interest to ISWC attendees.

2. Call for Tutorials
*******************************************
In addition to the regular research and workshop program, ISWC 2019 will
feature a tutorial program addressing the diverse interests of its
audience: Semantic Web practitioners that wish to learn about new
technologies, novices to the Semantic Web interested in introductory
tutorials to key Semantic Web / Linked Data topics, government and industry
representatives focusing on the applicability of Semantic Web / Linked Data
technologies in practical settings.
We hereby invite you to submit a tutorial proposal on a research topic
relevant to the ISWC 2019 audience.

3. Call for Semantic Web Challenges
*******************************************
ISWC 2019 will run multiple Challenges (SWCs) with the aim to evaluate and
compare software solutions for the Semantic Web in a systematic way. Each
SWC will:
* Define a task to be addressed,
* Provide a training and a test dataset and
* Define evaluation measures to compare the performance of participating
systems.
The organizers of each SWC will be responsible for the selection of the
participants who will be invited to present their solutions at ISWC 2019.
For ISWC 2019, SWC proposals are invited for any challenge involving
Semantic Web tasks, including but not limited to:
* Ontology alignment
* Fact checking
* Sentiment and Emotion analysis
* Entity resolution
* Link prediction
* Attribute prediction and validation
* Query and reasoning scalability
* Energy efficiency of computation (e.g. green processing)
* Stream processing
Selected SWC systems will be presented at ISWC 2019 on October 30, 2019.

Hello all!
We are having some issues with 2 of the Wikidata Query Service
servers. So far, the issue looks like data corruption, probably
related to an issue in Blazegraph itself (the database engine behind
Wikidata Query Service). The issue prevents updates to the data, but
reads are unaffected as far as we can tell.
The 2 affected servers are part of the internal WDQS cluster, so the
public wdqs endpoint [1] is not affected. Data is lagging on the
internal eqiad endpoint, so Mediawiki functionalities that use WDQS
are at the moment not seeing the latest updates to Wikidata.
We are reaching out to the Blazegraph team via Github [2] and via
private contacts that we have. We hope to identify the root cause of
the issue so that we can fix it for good, but this looks like a hard
problem. Failing that, we will reimport the full data set.
You can follow the upstream issue on Github [2] and on Phabricator on
our side [3].
Sorry for the inconvenience and thank you for your patience!
Have fun,
Guillaume

I think there is a higher probability of answer on the dedicated mailng
list, so I take the freedom to transfer the message (originally posted on
the sematic web mailing list)

Subject: Querying Wikidata
To: semantic-web <semantic-web(a)w3.org>
Hello,
Is there a good mean to query the sparql wdqs service of wikidata?
I've tried some python code to do it, with relative success.
Success, because some requests gives the expected result.
Relative, because the same query sometimes gives an empty response either
from my code or directly in the WDQS interface, where it's possible to see
that a sparql query sometimes gives an empty response, sometimes the
expected reponse without message or status to know that the response is
erroneous.
(demo is difficult, because it seems to depend of the load of the wdqs
service)
I've found the following info:
*
https://www.mediawiki.org/wiki/Wikidata_Query_Service/User_Manual#Query_lim…,
which suggest a possible error HTTP code 429, which I never receive
* https://phabricator.wikimedia.org/T179879, which suggest a possible
connexion with OAuth, but such possibility is never documented in the
official documentation
None of them gives a practical method to get a response and trust it.
Have you some advices?

Hello all,
The next IRC office hour with the Wikidata team will take place on January
8th 2019, from 18:00 to 19:00 (UTC+1, Berlin time), on the channel
#wikimedia-office.
As usual, we will present you some news from the development team, the
projects to come, and collect your feedback.
If you have any special topic you'd like to see as a focus, please share it
here!
Thanks,

Dear Wikidatans,
We are currently looking to fill two 100%-funded researcher positions in
the field of knowledge representation, AI, and data analysis. This might
be of interest to some of you, or to someone you know:
https://iccl.inf.tu-dresden.de/web/Jobs/en
Applicants should have (or be about to finish) a very good MSc degree or
equivalent in computer science or a related field (esp. mathematics).
Knowledge of Wikidata and related technologies is a plus but not a
requirement. Postdocs can also apply if their research is related to the
project.
Our research group is international, with English as the main language
in everyday work. The positions are part of a major collaborative
research project that aims at improving human understanding of software
systems, and which is starting just now; see
https://www.perspicuous-computing.science/ We aim to further increase
the share of female researchers in our team, so we'd like to encourage
women to apply [1].
I am happy to answer informal questions by email. The application
deadline is quite soon but it can (and probably will) be extended until
the positions are filled. Please feel free to forward this to anyone you
know who might be interested.
Cheers,
Markus
[1] All other genders, including men, are welcome too.
