Semantic Web Challenge CFP (ISWC 2015)

***************************************************************
Semantic Web Challenge 2015 - Call for Participation
http://challenge.semanticweb.org/2015/
Bethlehem, Pennsylvania
October 13-15, 2015
***************************************************************

Submissions are invited for the 2015 Semantic Web Challenge, the
premier event for demonstrating practical progress towards achieving
the vision of the Semantic Web. The 2015 Semantic Web Challenge which
will take place at the 15th International Semantic Web Conference in
Bethlehem, Pennsylvania.

The Semantic Web Challenge will consist of two tracks: the Open Track
and the Big Data Track. The key difference between the two tracks is
that the Big Data Track requires the participants to make use of large-
scale data sets. The Open Track has no such restrictions. The Challenge
is open to everyone from industry and academia. The authors of the best
applications will be awarded prizes and featured prominently at special
sessions during the conference.

Important Dates
*********************
Friday, September 11, 2015, 23:59 CET: Submissions due

Please note that you may need a visa to enter the US. You may have to
apply for a visa before the SWC deadline!

OWLED 2015: Call For Papers - DEADLINE EXTENSION

CALL FOR PAPER: 12th OWL: Experiences and Directions Workshop (OWLED)
Bethlehem, Pennsylvania (USA), October 9th - 10th, 2015 co-located with ISWC 2015

Important Dates (All deadlines are Hawaii time)
* Paper submission due: August 5, 2015 (EXTENDED)
* Acceptance notifications: September 4, 2015
* Final papers due: September 18, 2015
* OWLED workshop: 9-10 October, 2015

OWLED is now also a Community Group at the W3C. Everyone is invited to participate: http://www.w3.org/community/owled/ 

——————————————————————————————————————————————————

The aim of the OWL: Experiences and Directions Workshop (OWLED) is to establish an international forum for the OWL community, where practitioners in industry and academia, tool developers, and others interested in OWL can describe real and potential applications, share experiences and discuss requirements for language extensions/modifications. 

OWL has become the representational model of choice for supporting interoperability in many industries. With its rise in popularity, as well as the number of publicly available ontologies, it becomes important to focus on the processes by which ontologies can be engineered through reuse.

 In this edition of OWLED we aim to bridge the gap between ontology engineering practices and software engineering, where reuse is common practice, and we welcome submissions of papers describing reuse methods employed throughout the ontology development cycle; modeling / terminological decisions, alignment and comparison between ontologies, how ontologies are stored, versioned, distributed, and consumed over the Web. As with previous editions, we also welcome proposals for improving the OWL standard.
This year we also have a special ontology track, with submissions of ontologies that present interesting modelling problems or that can generate challenging tasks with respect to OWLED topics (e.g., ontologies that are challenging for reasoners to handle).

We invite submissions of the following types of papers:

Technical papers:  All submissions must be in English and be no longer than 12 pages (including references). Papers that exceed this limit will be rejected without review.  These papers should present research, implementation experience, and reports on the above and related topics. Space will be reserved for authors to present their work at the workshop.

Short papers (4-6 pages, including references): These papers should present work that is in an early stage and/or include publishable (novel) implemented systems that are of interest to the OWLED community; and (in case of an implemented system), can be demonstrated at the workshop.

Ontology papers (4-6 pages, including references): These papers should describe ontologies that present interesting modelling and other challenges with respect to OWLED topics (e.g., ontologies that are challenging for reasoners to handle or that demand features that are outside the standard OWL profiles). Papers are expected to include the URL of the ontology described.

 
All submissions must be in PDF, and must adhere to the Springer LNCS style. For more details, see Springer’s Author Instructions: http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0

Papers can be submitted online using the Easychair Conference system: 

Papers related to any aspects of OWL and extensions, applications, theory, methods and tools, are welcome. 
Topics of interest include, but are not limited to:
* Application driven requirements for (extensions of) OWL
* Applications of OWL, particularly
- from industry or
- for data integration
- for service interoperability
- for sophisticated/non-obvious inference
- for knowledge discovery
* and within specific domains such as
- law
- biology and biomedicine
- eLearning
* Experience of using OWL: notably, highly expressive ontologies or the OWL 2 Profiles
* Evaluation of OWL tools (e.g., ontology editors, versioning tools, reasoners)
* Benchmarks for OWL tools
* Performance and scalability issues and improvements
* Extensions to OWL
* OWL and Rules
* Ontology engineering  techniques and experience reports
* Non-standard reasoning services (implementation and requirements for)
* Explanation
* Translating natural language into OWL (and vice-versa, i.e., verbalisation)

* Reuse of OWL ontologies
* Tool descriptions and experience reports, including editors, visualisation, parsers and syntax checkers
* Collaborative editing of ontologies
* Comparison of OWL ontologies (diff)
* Versioning of OWL ontologies
* Alignment of OWL ontologies
* Ontology modularity and views
* Query answering with OWL
* SPARQL and OWL
* Linked Data and OWL
* Ontology-based data access (e.g., ontologies for big data, data integration, data fusion)
* Cognitive aspects of ontology engineering

Anonymous Individuals, RDF 1.1, and unnamed ontologies.

I'd like to canvass opinion on a few issues related to anonymous individuals in OWL 2.

1: Can/Must anonymous individuals be distinguished from RDF blank nodes?
  1. An RDF blank node identifier is defined to be scoped locally to a file or other RDF store [1, §3.4].
  2. An OWL 2 Anonymous Individual nodeID is defined to be scoped to an ontology [2,  § 5.6.2].
  3. The OWL 2 RDF mapping specification uses blank nodes to represent anonymous individuals. These are not freshly generated for each application of a translation rule. [3, §2.1]
  4. The mapping specification states that Import statements that are resolved to RDF graphs which do not contain an ontology header are treated as being included into the "importing" graph, via graph merging.  [2, §3.1.1].
  5. (1-3) seem to suggest that structurally equivalent nodeIDs in the documents in (4)  in should co-refer.
  6. If (5) holds, anonymous individuals in general cannot be represented as blank nodes.   
  7. If anonymous individuals are represented as blank nodes, does multiply "importing" an ontology with no header  and which contains anonymous individuals result in a fresh set of individuals for each import. 
2: Does importing a named  ontology via multiple IRIs generate fresh anonymous individuals for each import? 

3: Does importing an unnamed ontology via multiple IRIs generate fresh anonymous individuals for each import? 

4: Can anonymous individuals  in named ontologies be converted assigned IRIs as described in [1, §3.5]

5: Do Anonymous Individuals with the same nodeId, in ontologies with the same ontologyIRI but different versionIRIs co-refer diachronically? 

6: Can blank nodes in unnamed ontologies be converted to IRIs as described in [1, §3.5]?

Announcing OnToology, a tool for collaborative ontology development

Hi all,
We would like to introduce you to the beta version of OnToology (1), a tool that has been developed at the Ontology Engineering Group to help ontology developers who are keen on using GitHub to keep control of ontology versions in some of the last phases of the ontology development process.

OnToology helps ontology developers to document, evaluate, draw diagrams and publish ontologies, always providing them with the control on the generated outputs for additional editing.

OnToology integrates the OOPS! framework (2) for evaluation, Widoco (3) (based on LODE (4)) for documentation and the Ar2dTool (5) for the generation of taxonomy and entity-relationship diagrams. It also makes use of the Github pages (5) for the previsualisation of the generated HTML documentation.

How to use OnToology:
1. Enter your repository as user/repository i.e. myuser/myrepo (it does not work with organizations at the moment).
2. You will be redirected to Github to authorize OnToology to access your repository.
3. Update your repository and push.
4. OnToology will create pull request including generated files (documentation, diagrams and evaluation)
5. Merge the pull request created by OnToology

If you log in the OnToology portal with your Github account, you will also be able to monitor your repositories and enable/disable some of the features associated to them.

Examples:
See a step by step example here: http://ontoology.linkeddata.es/stepbystep. An example here of the generated contents here: https://github.com/dgarijo/test/tree/master/OnToology/test.owl (previsualization page is available at http://dgarijo.github.io/test/OnToology/test.owl/documentation/index.html)

OnToology is open source, and available in GitHub (7). We welcome your feedback (and your collaboration on adding more features)!

Best regards,
Ahmad Alobaid, Daniel Garijo, María Poveda-Villalón, Idafen Santana and Oscar Corcho (OnToology team)

Announcement

In today's information-centric world, effective access to and use of 
knowledge
is a key enabler for progress. Driven by the demands for intelligent
applications and the explosion of information on the Web, the study of 
Knowledge
Capture is crucially important. Knowledge Capture is the extraction of 
useful
knowledge from diverse sources: unstructured information sources,
semi-structured and structured data sources, knowledge graphs and 
directly from
crowds and individuals, either through observation or implicit or explicit
elicitation.
The wealth of information available from such a variety of sources calls 
for new
methods of Knowledge Capture that draw both from traditional knowledge
acquisition techniques and from more data-driven techniques such as 
large-scale
data mining, statistical analysis and data analytics.
Researchers and practitioners who work in the area of Knowledge Capture
traditionally participate in several distinct communities, including 
Knowledge
Engineering, Machine Learning, Natural Language Processing, Human-Computer
Interaction, Artificial Inteligence and the Semantic Web. K-CAP 2015 will
provide a forum to bring together members of disparate research 
communities who
are interested in all aspects of capturing knowledge from a variety of 
sources,
as well as those interested in creating representations that can be 
useful for
reasoning, analysis, and other forms of machine processing.

Venue

This year's K-CAP conference will be held at the Dolce Palisades Hotel and
Conference Center, just outside New York City. The Dolce Palisades is 
within 30
miles of the NYC airports: John F. Kennedy (JFK), LaGuardia (LGA), 
Newark (EWR)
and Westchester (HPN). The venue is minutes by car to Tarrytown Station, 
with
service to Grand Central Terminal in Manhattan.
K-CAP 2015 is also conveniently close in time and space to this year's
International Semantic Web Conference (ISWC 2015) at Lehigh University in
Bethlehem, Pennsylvania. Although the two conferences are not quite
"co-located", those at K-CAP 2015 can easily attend the last K-CAP plenary
session, have their free K-CAP lunch and make it to Bethlehem to check 
in prior
to the first day of ISWC activities.

Call for Submissions

We solicit high-quality research and application papers for publication and
presentation at the K-CAP 2015 conference. Submissions are welcome that 
address
any area of Knowledge Capture, including (but not limited to):

  ELEVENTH INTERNATIONAL WORKSHOP ON SCALABLE SEMANTIC WEB KNOWLEDGE BASE
                              SYSTEMS (SSWS2015)

                       http://www.ssws-ws.org/SSWS2015/

   At the 14th International Semantic Web Conference (ISWC2015), Bethlehem
   Pennsylvania, USA, October 11-15, 2015 http://iswc2015.semanticweb.org/

***************************************************************************

WORKSHOP DESCRIPTION

The  series of  SSWS workshops  aim at  creating a  forum for  discussing a
critical issue for the Semantic Web, that is, scalability.  As the Semantic
Web evolves, scalability becomes increasingly important. This workshop will
focus on addressing  the scalability issue with respect  to the development
and deployment of  knowledge base systems on the  Semantic Web.  Typically,
such systems deal with information described in Semantic Web languages like
OWL and RDF(S),  and provide services such as  storing, reasoning, querying
and debugging.  There are two basic requirements for these systems.  First,
they have  to satisfy the application's semantic  requirements by providing
sufficient reasoning support.  Second, they  must scale well in order to be
of  practical use.   Given the  sheer size  and distributed  nature  of the
Semantic Web, these requirements  impose additional challenges beyond those
addressed by earlier knowledge base systems.  This has been well recognized
by  the community  as demonstrated  by  the excitement  around the  billion
triples challenge.

We expect that the above issue is going to challenge the Semantic Web for a
long period of time and significant effort is needed in order to tackle the
problem.  This half day workshop seeks to bring  together  researchers  and
practitioners to  share their recent ideas and  progresses towards building
scalable knowledge base systems for the Semantic Web.

The workshop will be centered on  the discussion of three major aspects: 1)
foundations,   methods   and   technologies   for   pushing   forward   the
state-of-the-art;  2)   performance  evaluation  and   related  principles,
methodologies and  tools; 3) identification of important  issues and future
research directions.  Topics of interest  for the workshop include, but are
not limited to:

   * Semantic Web repositories
   * Reasoning mechanisms, techniques and systems
   * Query evaluation and optimization
   * Performance evaluation and benchmarks
   * Distributed knowledge base systems and P2P systems
   * Large scale knowledge base management
   * Semantic Web-based information integration

We expect that  the outcome of the workshop will  benefit not only Semantic
Web  developers but also  Semantic Web  evaluators and  end users.  We also
welcome   participants  from   related  disciplines   such   as  Artificial
Intelligence, Databases and Information Integration.

CFP: Final Call for Posters and Demonstrations -- ISWC-2015 (Deadline extended to 7th July, 2015)

Apologies for cross posting!

====

*** Call for Posters and Demonstrations -- ISWC-2015 ***
*** Submission Deadline is extended to 7th July, 2015***


The ISWC 2015 Posters and Demonstrations Track complements the Research Paper track of the conference and offers an opportunity for presenting late-breaking research results, on-going research projects, and speculative or innovative work in progress. The informal setting of the Posters and Demonstrations Track encourages presenters and participants to engage in discussions about the presented work. Such discussions can be invaluable inputs for the future work of the presenters, while offering participants an effective way to broaden their knowledge of the emerging research trends and to network with other researchers.
 
We invite submissions relevant to the area of the Semantic Web and which address, but are not limited to, the topics of the Research Track; the Evaluation & experiments track; and the Semantic Web In Use Track. Technical posters, reports on Semantic Web software systems, descriptions of completed work, and work in progress are all welcome. Demonstrations are intended to showcase innovative Semantic Web related implementations and technologies. All submissions are intended to convey a scientific result or work in progress and should not be advertisements for commercial software packages.
 
Authors of full papers accepted for the Research Track; Replication, Benchmark and Data Track; and Semantic Web In Use Track are explicitly invited to submit a poster or a demonstration. The submission should be formatted as the other posters and demonstrations but must cite the accepted full paper and needs to include an explanation of its added value with respect to the conference paper. The added value could include: a) extended results and experiments not presented in the conference paper for space reasons, or b) a demonstration of a supporting prototype implementation.
 
Submission Information
Authors must submit a four-page extended abstract for evaluation. All submissions will undergo a common review process, including those related to already accepted full papers. Decisions about acceptance will be based on relevance to the Semantic Web, originality, potential significance, topicality and clarity. For demonstrations, authors are strongly encouraged to include in their submission a link to where the demo (live or recorded video) can be found. They should also make clear what exactly will be demonstrated to the participants (e.g., what data sets will be used, which functionalities will be shown).
 
All papers and abstracts have to be submitted electronically via the EasyChair conference submission system: https://www.easychair.org/conferences/?conf=iswc2015pd 
 
Submissions must use the PDF file format and must adopt the style of the Springer Publications format for Lecture Notes in Computer Science (LNCS). Details are provided on Springer's Author Instructions page. Submissions that exceed the page limit will be rejected without review.
 
At least one of the authors must be a registered participant at the conference, and attend the Poster/Demo Session to present the work. The abstracts of accepted posters and demonstrations will be given to all conference attendees and published on the conference web site, but will not be published by Springer in the printed conference proceedings. They will, however, be compiled into a CEUR-WS Proceedings for easy Web retrieval and archival.
 
Metadata for all successful submissions will be included in the conference metadata corpus. Detailed information about metadata creation will be provided with the acceptance notification of the successful submissions.

Important Dates
- Poster & Demo Submission: July 7, 2015
- Notifications: Aug 6, 2015
- Camera-Ready Versions: August 21, 2015
 
All deadlines are Hawaii time (HST).

[CFP] Semantic Web Journal Special Issue on Quality Management of Semantic Web Assets (Data, Services and Systems)

The standardization and adoption of Semantic Web technologies has 
resulted in  a variety of assets, including an unprecedented volume of 
data being semantically enriched and systems and services, which consume 
or publish this data. Although gathering, processing and publishing data 
is a step towards further adoption of Semantic Web, quality does not yet 
play a central role in these assets (e.g., data lifecycle, 
system/service development).

Quality management essentially refers to activities and tasks involved 
to guarantee a certain level of consistency and to meet the quality 
requirements for the assets. In general, quality management consists of 
the following four phases and components: (i) quality planning, (ii) 
quality control, (iii) quality assurance and (iv) quality improvement.

The quality planning phase in the Semantic Web typically involves the 
design of procedures, strategies and policies to support the management 
of the assets. The quality control and assurance components have their 
primary aim in preventing errors and to meet quality requirements 
pertaining to the Semantic Web standards. A core part for both 
components are quality assessment methods which provide the necessary 
input for the controlling and assurance tasks.

Quality assessment of Semantic Web Assets (data, services and systems), 
in particular, presents new challenges that were not handled before in 
other research areas. Thus, adopting existing approaches for data 
quality assessment is not a straightforward solution. These challenges 
are related to the openness of the Semantic Web, the diversity of the 
information and the unbounded, dynamic set of autonomous data sources, 
publishers and consumers (legal and software agents). Additionally, 
detecting the quality of available data sources and making the 
information explicit is yet another challenge. Moreover, noise in one 
data set, or missing links between different data sets, propagates 
throughout the Web of Data, and imposes great challenges on the data 
value chain.

In case of systems and services, different implementations follow the 
specifications for RDF and SPARQL to varying extents, or even propose 
and offer new, non-standardized extensions. This causes strong 
incompatibilities between systems, e.g., between the used SPARQL 
features in the query engines and support features in RDF stores. The 
potential heterogeneity and incompatibility poses several challenges for 
the quality assessments in and for such systems and services.

Eventually, quality improvement methods are used to further enhance the 
value of the Semantic Web Assets. One important step to improve the 
quality of data is identifying the root cause of the problem and then 
designing corresponding data improvement solutions. These solutions 
select the most effective and efficient strategies and related set of 
techniques and tools to improve quality. Quality improvement metrics for 
products and services entails understanding and improving operational 
processes and establishing valid and reliable service performance measures.

This Special Issue is addressed to those members of the community 
interested in providing novel methodologies or frameworks in managing, 
assessing, monitoring, maintaining and improving the quality of the 
Semantic Web data, services and systems and also introduce tools and 
user interfaces which can effectively assist in this management.
