Sorry for cross-posting!
Reminder: Technical Advice IRC meeting this week **Wednesday 3-4 pm UTC**
on #wikimedia-tech.
Questions can be asked in English and German!
The Technical Advice IRC Meeting (TAIM) is a weekly support event for
volunteer developers. Every Wednesday, two full-time developers are
available to help you with all your questions about Mediawiki, gadgets,
tools and more! This can be anything from "how to get started" over "who
would be the best contact for X" to specific questions on your project.
If you know already what you would like to discuss or ask, please add your
topic to the next meeting:
https://www.mediawiki.org/wiki/Technical_Advice_IRC_Meeting
Hope to see you there!

... Most often we need to integrate together data sources that were not
aiming at their
integration while being designed, thus, increasing the difficulty of the
matching operation.
Even if a good progress has been made in the matching field as such,
ontology
matching may appear to be virtually impossible. Indeed, for finding the
correspondences
between entities, it is necessary to understand their meaning ...

FINAL CALL FOR CONTRIBUTIONS
THE SUBMISSION DEADLINE IS APPROACHING ON JUNE 28TH, 2019

The Fourteenth International Workshop on
ONTOLOGY MATCHING
(OM-2019)
http://om2019.ontologymatching.org/
October 26th or 27th, 2019, ISWC Workshop Program,
Auckland, New Zealand
BRIEF DESCRIPTION AND OBJECTIVES
Ontology matching is a key interoperability enabler for the Semantic Web,
as well as a useful technique in some classical data integration tasks
dealing with the semantic heterogeneity problem. It takes ontologies
as input and determines as output an alignment, that is, a set of
correspondences between the semantically related entities of those
ontologies.
These correspondences can be used for various tasks, such as ontology
merging, data interlinking, query answering or process mapping.
Thus, matching ontologies enables the knowledge and data expressed
with the matched ontologies to interoperate.
The workshop has three goals:
1.
To bring together leaders from academia, industry and user institutions
to assess how academic advances are addressing real-world requirements.
The workshop will strive to improve academic awareness of industrial
and final user needs, and therefore, direct research towards those needs.
Simultaneously, the workshop will serve to inform industry and user
representatives about existing research efforts that may meet their
requirements. The workshop will also investigate how the ontology
matching technology is going to evolve, especially with respect to
data interlinking, process mapping and web table matching tasks.
2.
To conduct an extensive and rigorous evaluation of ontology matching
and instance matching (link discovery) approaches through
the OAEI (Ontology Alignment Evaluation Initiative) 2019 campaign:
http://oaei.ontologymatching.org/2019/
3. To examine new uses, similarities and differences from database
schema matching, which has received decades of attention
but is just beginning to transition to mainstream tools.
This year, in sync with the main conference, we encourage submissions
specifically devoted to: (i) datasets, benchmarks and replication studies,
services, software, methodologies, protocols and measures
(not necessarily related to OAEI), and (ii) application of
the matching technology in real-life scenarios and assessment
of its usefulness to the final users.
TOPICS of interest include but are not limited to:
Business and use cases for matching (e.g., big, open, closed data);
Requirements to matching from specific application scenarios (e.g.,
public sector, homeland security);
Application of matching techniques in real-world scenarios (e.g., with
environmental data);
Formal foundations and frameworks for matching;
Matching and knowledge graphs;
Matching and deep learning;
Matching and embeddings;
Matching and big data;
Matching and linked data;
Instance matching, data interlinking and relations between them;
Privacy-aware matching;
Process model matching;
Large-scale and efficient matching techniques;
Matcher selection, combination and tuning;
User involvement (including both technical and organizational aspects);
Explanations in matching;
Social and collaborative matching;
Uncertainty in matching;
Reasoning with alignments;
Alignment coherence and debugging;
Alignment management;
Matching for traditional applications (e.g., data science);
Matching for emerging applications (e.g., web tables, knowledge graphs).
SUBMISSIONS

posters/statements of interest addressing different issues of ontology
matching

What's the best way to search Wikidata for items whose name or alias
matches a string? The search available via pywikibot seems to only find a
match if the search string is a prefix of an item's name or alias, so
searching for "Bush" does not return any of the the George Bush items. I
don't want to use a SPARQL query with a regex, since I expect that to be
slow.
The search box on the Wikidata pages is closer to what I want. Is there a
good way to call this via an API?
Ideally, I'd like to be able to specify a language and also a set of types,
but I can do that once I've identified candidates based on a simple match
with a query string.
Hello all,
The Celtic Knot Conference
<https://meta.wikimedia.org/wiki/Celtic_Knot_Conference_2019>, dedicated to
languages in the Wikimedia projects, will take place on 4th and 5th of July
in Penryn, Cornwall, UK.
The conference aims to bring people together to share their experiences of
working on sharing information in minority languages, and to help people
learn how to encourage the flow of information across language barriers and
support associated communities.
During the previous editions
<https://wikimedia.org.uk/wiki/Celtic_Knot_Conference_2018#Programme>, a
lot of Wikidata-related sessions took place, and the conference especially
helped bringing together editors of small Wikipedia communities who wanted
to make more use of Wikidata
<https://blog.wikimedia.org.uk/2018/08/celtic-knot-2018-how-can-wikidata-sup…>,
but lacked resources or technical skills. We hope that this gathering will
bring together again plenty of people who are enthusiastic about sharing
knowledge across (project) borders and languages!
The call for program submissions is now open until May 16th. More
information about attendance and possible ways to get funded will certainly
follow.
I already submitted a Query Booth
<https://meta.wikimedia.org/wiki/Celtic_Knot_Conference_2019/Submissions/Que…>
- the format where people can exchange knowledge about SPARQL and help each
other to build queries has been successfully tested at the WikidataCon and
other events. If you plan to join the conference and would like to help at
the booth, feel free to register on the page!
if you have any question, feel free to reach me or the main organisation
contact, Mark Trevethan.
Cheers,

Hoi,
Query performance has never been this bad. Currently the lag is over 6
HOURS.. and rising
My previous question stands.. What is the plan because we do not cope.
Thanks,
GerardM
PS Today I was busy assembling Ikea furniture.. It was not me.
My Query:
SELECT ?item ?itemLabel WHERE {
?item wdt:P31 wd:Q2085381.
SERVICE wikibase:label { bd:serviceParam wikibase:language
"[AUTO_LANGUAGE],en". }
# FILTER(CONTAINS(LCASE(?itemLabel), "simon"))
# FILTER (LANG(?itemLabel)="en")
}
and if I enable any of the FILTER lines, it returns 0 results.
What changed / Why ?
