MOTIVATION AND OBJECTIVES
This is the next iteration of the successful Semantic Publishing
Challenge of ESWC 2014. We continue pursuing the objective of
assessing the quality of scientific output, evolving the dataset
bootstrapped in 2014 to take into account the wider ecosystem of
To achieve that, this year’s challenge focuses on refining and
enriching an existing linked open dataset about workshops, their
publications and their authors.
Aspects of “refining and enriching” include extracting deeper
information from the HTML and PDF sources of the workshop proceedings
volumes and enriching this information with knowledge from existing
Thus, a combination of broadly investigated technologies in the
Semantic Web field, such as Information Extraction (IE), Natural
Language Processing (NLP), Named Entity Recognition (NER), link
discovery, etc., is required to deal with the challenge’s tasks.
The Challenge is open to everyone from industry and academia.
We ask challengers to automatically annotate a set of multi-format
input documents and to produce a LOD that fully describes these
documents, their context, and relevant parts of their content. The
evaluation will consist of evaluating a set of queries against the
produced dataset to assess its correctness and completeness.
The primary input dataset is the LOD that has been extracted from the
CEUR-WS.org workshop proceedings using the winning extraction tool of
the 2014 challenge, plus its full original HTML and PDF source
documents. In addition, the challenge uses (as linking targets)
existing LOD on scholarly publications.
The input dataset will be split in two parts: a training/testing part
and an evaluation part, which will disclosed a few days before the
submission deadline. Participants will be asked to run their tool on
the evaluation dataset and to produce the final Linked Open Dataset.
Further details about the organization will be provided in the Challenge wiki.
The Challenge will include three tasks:
Task 1: Extraction and assessment of workshop proceedings information
Participants are required to extract information from a set of HTML
tables of contents and PDF papers published in CEUR-WS.org workshop
proceedings. The extracted information is expected to answer queries
about the quality of these workshops, for instance by measuring
growth, longevity, etc. The task is an extension of the Task 1 of the
2014 Challenge: we will reuse the most challenging quality indicators
from last year’s challenge, others will be defined more precisely,
others will be completely new.
Task 2: Extracting contextual information from the full text of the papers
Participants are required to extract information from the textual
content of the paper. That information should provide a deeper
understanding of the context in which it was written.
In particular, the extracted information is expected to answer queries
about authors’ affiliations and research institutions, research grants
and fundings, and related works (papers presented in the same venue,
addressing similar issues, etc.). The task mainly requires NLP and
Entity Recognition techniques.
Task 3: Interlinking
Participants are required to interlink the CEUR-WS.org linked dataset
with relevant datasets already existing at the Linked Open Data cloud.
In particular, they are expected to interlink persons, papers, events,
organizations and publications. All these entities should be
identified, disambiguated and interlinked to their correspondences at
other LOD datasets. Task 3 can be accomplished either as a named
entity recognition and disambiguation task (NLP based entity linking),
or as an entity interlinking task, or as a combination of methods.
Participants will be requested to submit the LOD that their tool
produces from the evaluation dataset, as well as a paper that
describes their approach. They will also be given a set of queries in
natural language form and will be asked to translate those queries
into a SPARQL form that works on their LOD.
The results of the queries on the produced LOD will be compared with
the expected output, and precision and recall will be measured to
identify the best performing approach. Separately, the most original
approach will be assigned by the Program Committee.
FEEDBACK AND DISCUSSION
A discussion group is open for participants to ask questions and to
receive updates about the challenge:
Participants are invited to subscribe to this group as soon as
possible and to communicate their intention to participate. They are
also invited to use this channel to discuss problems in the input
dataset and to suggest changes.
JUDGING AND PRIZES
After a first round of review, the Program Committee and the chairs
will select a number of submissions conforming to the challenge
requirements that will be invited to present their work. Submissions
accepted for presentation will receive constructive reviews from the
Program Committee, they will be included in the Springer LNCS
post-proceedings of ESWC.
We are also planning to allow winners to present their work in a
special slot of the main program and to invite them to submit an
extended version of their paper to an international journal.
Six winners will be selected. For each task we will select:
* best performing tool, given to the paper which will get the highest
score in the evaluation
* most original approach, selected by the Challenge Committee with the
HOW TO PARTICIPATE
Participants are required to submit:
* Abstract: no more than 200 words.
* Description: It should explain the details of the automated
annotation system, including why the system is innovative, how it uses
Semantic Web technology, what features or functions the system
provides, what design choices were made and what lessons were learned.
The description should also summarize how participants have addressed
the evaluation tasks. An outlook towards how the data could be
consumed is appreciated but not strictly required. Papers must be
submitted in PDF format, following the style of the Springer's Lecture
Notes in Computer Science (LNCS) series
(http://www.springer.com/computer/lncs/lncs+authors), and not
exceeding 12 pages in length.
* The Linked Open Dataset produced by their tool on the evaluation
dataset (as a file or as a URL, in Turtle or RDF/XML).
* A set of SPARQL queries that work on that LOD and correspond to the
natural language queries provided as input
Participants will also be asked to submit their tool (source and/or
binaries, or a link these can be downloaded from, or a web service
URL) for verification purposes.
Further submission instructions will be published on the challenge wiki.
All submissions should be provided via the submission system linked
from the homepage.
We invite the potential participants to subscribe to our mailing list
at https://groups.google.com/forum/#!forum/sempub2015 in order to be
kept up to date with the latest news related to the challenge.
