Hi,
I'm looking into ways to use tabular data like
https://commons.wikimedia.org/wiki/Data:Zika-institutions-test.tab
in SPARQL queries but could not find anything on that.
My motivation here is in part coming from the time out limits, and the
basic idea here would be to split queries that typically time out into
sets of queries that do not time out and - if their results were
aggregated - would yield the results that would be expected for the
original query would it not time out.
The second line of motivation here is that of keeping track of how
things develop over time, which would be interesting for both content
and maintenance queries as well as usage of things like classes,
references, lexemes or properties.
I would appreciate any pointers or thoughts on the matter.
Thanks,
Daniel

1. Call for Papers - Research Track
*******************************************
The research track of ESWC 2020 is looking for novel and significant research contributions addressing theoretical, analytical and empirical aspects of the Semantic Web. We also encourage contributions to research at the intersection of Semantic Web and other scientific disciplines. Submissions to the research track should describe original, significant research on the Semantic Web, and are expected to provide some principled means of evaluation. Specifically, all papers should include evaluations of the approaches described in the paper. We strongly encourage evaluations that are repeatable. We also strongly encourage papers that provide links to: the data sets, source code, queries and other resources.
Based on previous years submissions, this year we are setting up ten research tracks that reflect some of the main research areas of the Semantic Web and its intersection with other scientific disciplines:
* Ontologies and Reasoning

2. Call for Papers - Resources Track
*******************************************
Many of the research efforts in the areas of the Semantic Web,Linked Data and Knowledge Graphs focus on publishing scientific papers that prove a hypothesis. However, scientific advancement is often reliant on good quality resources that provide the necessary scaffolding to support the scientific publications. Sharing these resources and the best practices that have lead to their development with the research community is crucial, to consolidate research material, ensure reproducibility of results and in general gain new scientific insights.
The ESWC 2020 Resources Track aims to promote the sharing of resources including, but not limited to: datasets, ontologies, vocabularies, annotated corpora, workflows, knowledge graphs, evaluation benchmarks or methods, replication studies, services, APIs and software frameworks that have contributed to the generation of novel scientific work. In particular, we encourage the sharing of such resources following best and well established practices within the Semantic Web community, including the provision of an open license and a permalink identifying the resource. This track calls for contributions that provide a concise and clear description of a resource and its usage. A typical Resource track paper has its focus set on reporting on one of the following categories:
* Ontologies developed for an application, with a focus on describing the modelling process underlying their creation;
* Datasets produced to support specific evaluation tasks or by a novel algorithm;
* Knowledge graphs or remarkable interest that comprehensively cover new vertical domains;
* Machine learning models that would impact the knowledge engineering community. Examples include comprehensive word embeddings trained on large corpora, or embeddings of commonly known knowledge graphs, such as DBpedia or Wikidata
* Descriptions of a reusable research prototype / service supporting a given research hypothesis;
* Descriptions of a dataset produced by a novel algorithm;
* Descriptions of community shared software frameworks that can be extended or adapted to support scientific study and experimentation;
* Benchmarking, focusing on datasets and algorithms for comprehensible and systematic evaluation of existing and future systems;
* Development of new evaluation methodologies, and their demonstration in an experimental study.

3. Call for Papers - In-Use Track
*******************************************
Semantic technologies are reaching maturity on and off the web. The In-Use track at ESWC 2020 provides a forum for the community to explore the benefits and challenges of applying semantic technologies in concrete, practical applications, in contexts ranging from industry to government and science. We are especially interested in applications that use the emerging knowledge graphs or semantic annotations on the web together with data mining, machine learning, or natural language processing techniques to the benefit of concrete, real-life scenarios. We are also looking for descriptions of applied and validated industry solutions as software tools, systems or architecture that benefit from the adoption of semantic technologies.
Importantly, papers presenting applications in use of semantic technologies should provide evidence that there is use of the proposed application or tool by the target user group, preferably outside the group that conducted the development. A main focus of the submission should be on the way semantics and semantic technologies are impacting this development, through benefiting the intended use case, as well as, if relevant, through the added challenges they introduce.
Topics of Interest:
We invite the submission of original papers organized around some of the following aspects:
* Description and analysis of concrete problems and user requirements for applying semantic technologies in a specific domain
* Descriptions of how Semantic Web resources (ontologies, datasets, software, standards, etc) are being used in practice
* Analysis and evaluation of usability and uptake of Semantic Web tools and technologies
* Scalability analysis and large scale deployment in real world scenarios
* Assessment of the pros and cons of using semantic technologies to solve a particular and practical problem
* Comparison of semantic technologies with alternative approaches that use conventional or competing technologies
* Learned lessons and best practices from deploying and using an application or service based on Semantic Web technologies
* Assessment of costs and benefits of implementing, deploying, using, and managing Semantic Web technologies
* Analysis of risks and opportunities of using Semantic Web technologies in organizations with respect to their businesses and customers
* Descriptions of alternative semantic technologies being deployed in practice
* Mobile apps based on semantic technologies that have substantial user base
* Applications in domain-specific areas such as Health & Life Sciences, Digital Libraries & Cultural Heritage, Media & Entertainment, Smart Cities, and Open Government

Hello all!
As you've probably noticed, the update lag on the public WDQS endpoint [1]
is not doing well [2], with lag climbing to > 12h for some servers. We are
tracking this on phabricator [3], subscribe to that task if you want to
stay informed.
To be perfectly honest, we don't have a good short term solution. The graph
database that we are using at the moment (Blazegraph [4]) does not easily
support sharding, so even throwing hardware at the problem isn't really an
option.
We are working on a few medium term improvements:
* A dedicated updater service in Blazegraph, which should help increase the
update throughput [5]. Finger crossed, this should be ready for initial
deployment and testing by next week (no promise, we're doing the best we
can).
* Some improvement in the parallelism of the updater [6]. This has just
been identified. While it will probably also provide some improvement in
throughput, we haven't actually started working on that and we don't have
any numbers at this point.
Longer term:
We are hiring a new team member to work on WDQS. It will take some time to
get this person up to speed, but we should have more capacity to address
the deeper issues of WDQS by January.
The 2 main points we want to address are:
* Finding a triple store that scales better than our current solution.
* Better understand what are the use cases on WDQS and see if we can
provide a technical solution that is better suited. Our intuition is that
some of the use cases that require synchronous (or quasi synchronous)
updates would be better implemented outside of a triple store. Honestly, we
have no idea yet if this makes sense and what those alternate solutions
might be.
Thanks a lot for your patience during this tough time!

may be asked to submit a white paper or position statement.
-
Mini-conferences on specialized topics, having their own paper
submission and review processes.
-
Mini-competitions or challenges around selected topics with individual
or team participation.
-
Interactive discussion meetings focusing on subtopics of the UMAP
general research topics.
-
Joint panels for different workshops.
