Workshop Summary
================
The goal of this workshop is to explore and strengthen the relationship
between the Semantic Web and statistical communities, to provide better
access to the data held by statistical offices. It will focus on ways in
which statisticians can use Semantic Web technologies and standards in
order to formalize, publish, document and link their data and metadata,
and also on how statistical methods can be applied on linked data. It
follows two very successful edition of the Semantic Statistics workshop
held at ISWC 2013 (SemStats 2013) and at ISWC 2014 (SemStats 2014).
The statistical community has recently shown an interest in the Semantic
Web. In particular, initiatives have been launched to develop semantic
vocabularies representing statistical classifications and discovery
metadata. Tools are also being created by statistical organizations to
support the publication of dimensional data conforming to the Data Cube
W3C Recommendation. But statisticians see challenges in the Semantic
Web: how can data and concepts be linked in a statistically rigorous
fashion? How can we avoid fuzzy semantics leading to wrong analyses? How
can we preserve data confidentiality?
The workshop will also cover the question of how to apply statistical
methods or treatments to linked data, and how to develop new methods and
tools for this purpose. Except for visualisation techniques and tools,
this question is relatively unexplored, but the subject will obviously
grow in importance in the near future.
Motivation
==========
There is a growing interest regarding linked data and the semantic web
in the statistical community. A large amount of statistical data from
international and national agencies has already been published on the
web of data, for example Census data from Ireland, Italy or France
amongst others. In most cases, though, this publication is done by
actors exterior to the statistical office (see in particular
http://270a.info/, http://eurostat.linkedstatistics.org/ or
http://linkedstatistics.gr/), which raises issues such as longterm URI
persistence, institutional commitment and data maintenance.
Statistical organizations also possess an important corpus of structural
metadata such as concept schemes, thesaurii, code lists and
classifications. Some of those are already available as linked data,
generally in SKOS format (e.g. FAO's Agrovoc or UN's COFOG). Semantic
web standards useful for the statisticians have now arrived at maturity.
The best examples are the W3C Data Cube, DCAT and ADMS vocabularies. The
statistical community is also working on the definition of more
specialized vocabularies, especially under the umbrella of the DDI
Alliance. For example, XKOS extends SKOS for the representation of
statistical classifications, and Disco defines a vocabulary for data
documentation and discovery. The Visual Analytics Vocabulary is a first
step towards semantic descriptions for user interface components
developed to visualize Linked Statistical Data which can lead to
increased linked data consumption and accessibility. We are now at the
tipping point where the statistical and the semantic web communities
have to formally exchange in order to share experiences and tools and
think ahead regarding the upcoming challenges.
The web of data will benefit in getting rich data published by
professional and trustworthy data providers. It is also important that
metadata maintained by statistical offices like concept schemes of
economic or societal terms, statistical classifications, wellknown
codes, etc., are available as linked data, because they are of good
quality, wellmaintained, and they constitute a corpus to which a lot of
other data can refer to.
Statisticians have a long-going culture of data integrity, quality and
documentation. They have developed industrialized data production and
publication processes, and they care about data confidentiality and more
generally how data can be used. It seems that after a period where the
aim was to publish as many triples as possible, the focus of the
Semantic Web community is now shifting to having a better quality of
data and metadata, more coherent vocabularies (see the LOV initiative),
good and documented naming patterns, etc. This workshop aims to
contribute in these longer term problems in order to have a significant
impact.
The statistics community faces sometimes challenges when trying to adopt
Semantic Web technologies, in particular:
* difficulty to create and publish linked data: this can be alleviated
by providing methods, tools, lessons learned and best practices, by
publicizing successful examples and by providing support.
* difficulty to see the purpose of publishing linked data: we must
develop end-user tools leveraging statistical linked data, provide
convincing examples of real use in applications or mashups, so that the
end-user value of statistical linked data and metadata appears more clearly.
* difficulty to use external linked data in their daily activity: it is
important to develop statistical methods and tools especially tailored
for linked data, so that statisticians can get accustomed to using them
and get convinced of their specific utility.
To conclude, statisticians know how misleading it can be to exploit
semantic connections without carefully considering and weighing
information about the quality of these connections, the validity of
inferences, etc. A challenge for them is to determine, to ensure and to
inform consumers about the quality of semantic connections which may be
used to support analysis in some circumstances but not others. The
workshop will enable participants to discuss these very important issues.
Topics
======
The workshop will address topics related to statistics and linked data.
This includes but is not limited to:
How to publish linked statistics?
* What are the relevant vocabularies for the publication of statistical
data?
* What are the relevant vocabularies for the publication of statistical
metadata (code lists and classifications, descriptive metadata,
provenance and quality information, etc.)?
* What are the existing tools? Can the usual statistical software
packages (e.g. R, SAS, Stata) do the job?
* How do we include linked data production and publication in the data
lifecycle?
* How do we establish, document and share best practices?
How to use linked data for statistics?
* Where and how can we find statistics data: data catalogues, dataset
descriptions, data discovery?
* How do we assess data quality (collection methodology, traceability,
etc.)?
* How can we perform data reconciliation, ontology matching and instance
matching with statistical data?
* How can we apply statistical processes on linked data: data analysis,
descriptive statistics, estimation, correction?
* How to intuitively represent statistical linked data: visual
analytics, results of data mining?
Submissions
===========
This workshop is aimed at an interdisciplinary audience of researchers
and practitioners involved or interested in Statistics and the Semantic
Web. All papers must represent original and unpublished work that is not
currently under review. Papers will be evaluated according to their
significance, originality, technical content, style, clarity, and
relevance to the workshop. At least one author of each accepted paper is
expected to attend the workshop.
Workshop participation is available to ISWC 2015 attendants at an
additional cost, see http://iswc2015.semanticweb.org/registration for
details.
The workshop will also feature a challenge based on Census Data
published on the web or provided by Statistical Institutes. It is
expected that data from Australia, France and Italy will be available.
The challenge will consist in the realization of mashups or
visualizations, but also on comparisons, alignment and enrichment of the
data and concepts involved.
We welcome the following types of contributions:
* Full research papers (up to 12 pages)
* Short papers (up to 6 pages)
* Challenge papers (up to 6 pages)
All submissions must be written in English and must be formatted

http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0). Please
note that (X)HTML(+RDFa) submissions are also welcome as long as the
layout complies with the LNCS style. Authors can for example use the
template provided at https://github.com/csarven/linked-research.
Submissions are NOT anonymous. Please submit your contributions
