ESWC-16 Open Knowledge Extraction (OKE) Challenge

May 29th, 2016 - June 2nd, 2016
Anissaras, Crete, Greece

################################################
The OKE challenge, launched as first edition at last year Extended
Semantic Web Conference, ESWC2015, has the ambition to provide a
reference framework for research on Knowledge Extraction from text for
the Semantic Web by re-defining a number of tasks (typically from
information and knowledge extraction), taking into account specific SW
requirements.
The OKE challenge defines three tasks, each one having a separate dataset:
1 - Entity Recognition, Linking and Typing for Knowledge Base population
2 - Class Induction and entity typing for Vocabulary and Knowledge Base
enrichment
3 - Web-scale Knowledge Extraction by Exploiting Structured Annotation.
Task 1 consists of identifying Entities in a sentence and create an OWL
individual representing it, link to a reference KB (DBpedia) when
possible and assigning a type to such individual.
Task 2 consists in producing rdf:type statements, given definition
texts. The participants will be given a dataset of sentences, each
defining an entity (known a priori).
Task 3 will be based on one of the largest, publicly available
collections of triples extracted from HTML pages (provided by the Web
Data Commons project). Participants will use annotated Web pages as
stimuli for training a Web-scale extraction system which is capable of
extracting structured data from non-annotated pages.
Full details about the tasks and related data and material can be found at

Important Dates
- Challenge papers submission deadline: Friday March 11th, 2016
- Challenge paper reviews due: Tuesday April 5th, 2016
- Notifications sent to participants: Friday April 8th, 2016
- Test data published: Friday April 8th, 2016
- Camera ready papers due: Sunday April 24th, 2016
Participants must:
1. Submit a paper describing their system, via
[EasyChair](https://easychair.org/conferences/?conf=oke2015), no later
then **March 11th, 2016**. The paper should contain the details of the
system, including why the system is innovative, how it uses Semantic
Web, which features or functions the system provides, what design
choices were made and what lessons were learned. The description should
also summarise how participants have addressed the evaluation task(s).
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.
2. For task 1 and 2 provide access to the application as webservice
(specifications can be found at
https://github.com/anuzzolese/oke-challenge-2016/blob/master/example_data/GERBIL_integration.md
),
with input/output provided in NIF format. The final evaluation will be
carried out via GERBIL (http://gerbil.aksw.org). The implementation of
the evaluation for tasks 1-2 is already available on GERBIL (also
accessible as open source code) as Web
demo(http://gerbil.aksw.org/gerbil/config). Participants can
autonomously test their system using GERBIL (selecting as Experiment
Type either OKE Challenge 2015 - Task 1 or OKE Challenge 2015 - Task 2).
For task 3 participants will have to produce results in the specified
format.
3. The URI for the final system (for task1-2) / results on test set (for
task 3) must be provided by **April 8th, 2016** when the organizers
will evaluate the systems against the evaluation datasets, which will be
publicly released after announcement of results.
