The central role of Wikipedia (and therefore DBpedia) for the creation of a
Translingual Web has been recognized by the Strategic Research Agenda
(cf. section 3.4, page 23) and most of the contributions of the Dagstuhl
seminar on the Multilingual Semantic Web also stress the role of Wikipedia
for Multilingualism. The previous editions of the NLP&DBpedia workshop also
contribute to this understanding.

As more and more language-specific chapters of DBpedia are created
(currently 14 language editions), DBpedia is becoming a driving factor for a
Linguistic Linked Open Data cloud as well as localized LOD clouds with
specialized domains (e.g. the Dutch windmill domain ontology created from or Japanese domain ontology of screws from

The data contained in Wikipedia and DBpedia have ideal properties for making
them a controlled testbed for NLP. Wikipedia and DBpedia are multilingual
and multi-domain, the communities maintaining these resource are very open
and it is easy to join and contribute. The open licence allows data
consumers to benefit from the content and many parts are collaboratively
editable. Especially, the data in DBpedia is widely used and disseminated
throughout the Semantic Web.

With the foundation of the DBpedia Association and the frequent releases of
the DBpedia+ Data Stack, this workshop hopes to channel contributions of the
NLP research community into the data ecosystem of DBpedia and LOD, thus
easing the use of interlinked language resources as well as increasing the
performance of knowledge-based NLP approaches.

We envision the workshop to produce the following items:
* an open call to the DBpedia data consumer community that will generate
a wish list of data, which is to be generated from Wikipedia using NLP
methods (for certain domains and application scenarios). This wish list
will be broken down to tasks and benchmarks and as a result GOLD
standard will be created.
* the benchmarks and test data created will be collected and published
under an open licence for future evaluation (inspired by and
* strengthen the link between DBpedia and NLP communities that currently
meet two times a year at DBpedia developers workshops.
We also offer all authors the chance to contribute their data to the
regular DBpedia releases in April and October.

DBpedia has been around for quite a while, infusing the Web of Data with
multi-domain data of decent quality. The data in DBpedia is, however, mostly
extracted from Wikipedia infoboxes, while the remaining parts of Wikipedia
are to a large extent not exploited for DBpedia. Here, NLP techniques may
help improving DBpedia.

Extracting additional triples from the plain text information in Wikipedia,
either unsupervised or using the existing triples as training information,
could multiply the information in DBpedia, or help telling correct from
incorrect information by finding supporting text passages. Furthermore,
analyzing the semantics of other structures in Wikipedia, such as tables,
lists, or categories, would help make DBpedia richer. Finally, since
Wikipedia exists in more than 200 languages, we are particularly interested
in seeing NLP approaches not only working for English, but also for other
languages, in order to leverage the huge amount of knowledge captured in the
different language editions.

NLP approaches enable also improving quality of DBpedia, especially by
extracting content from sources other than Wikipedia that may validate the
data in DBpedia.

On the other hand, NLP and information extraction techniques often involve
various resources while processing texts from different domains. As
high-quality annotated data is often too expensive and time-consuming to
obtain, NLP researchers are increasingly looking to the Semantic Web for
external structured sources to complement their datasets. Such resources can
be gazetteers to aid a named entity recognition system or examples of
relations between entities to bootstrap a relation finder. DBpedia can
easily be utilised to assist NLP modules in a variety of tasks.

We invite papers from both these areas including:
* Knowledge extraction from text and HTML documents (especially
unstructured and semi-structured documents) on the Web, using
information in the Linked Open Data (LOD) cloud, and especially in DBpedia.
* Representation of NLP tool output and NLP resources as RDF/OWL, and
linking the extracted output to the LOD cloud or the Linguistic LOD cloud .
* Novel applications using the extracted knowledge, the Web of Data or
NLP DBpedia-based methods.

Topics include, but are not limited to

* Enhancing DBpedia with NLP methods
* Finding errors in DBpedia with NLP methods
* Enriching DBpedia with NLP methods
* Improving quality of DBpedia with NLP methods
* Annotation methods for Wikipedia articles
* Cross-lingual data and text mining on Wikipedia
* Pattern and semantic analysis of natural language, reading the Web,
learning by reading
* Large-scale information extraction
* Entity resolution and automatic discovery of Named Entities
* Multilingual entity recognition task of real world entities
* Frequent pattern analysis of entities
* Relationship extraction, slot filling
* Entity linking, Named Entity disambiguation, cross-document
co-reference resolution
* Disambiguation through knowledge base
* Ontology representation of natural language text
* Analysis of ontology models for natural language text
* Learning and refinement of ontologies
* Natural language taxonomies modeled to Semantic Web ontologies
* Use cases of entity recognition for Linked Data applications
* Impact of entity linking on information retrieval, semantic search
Furthermore, an informal list of NLP tasks can be found on this
Wikipedia page:
These are relevant for the workshop as long as they fit into the
DBpedia4NLP and NLP4DBpedia frame (i.e. the used data evolves around
Wikipedia and DBpedia).

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. Accepted papers will be published through CEUR-WS.

We welcome the following types of contributions:
* Full research papers (up to 12 pages).
* Position papers (up to 6 pages)
* Use case descriptions (up to 6 pages)
* Data/benchmark papers (2-6 pages, depending on the size and complexity)

All submissions must be written in English and must be formatted according
to the style for Lecture Notes in Computer Science (LNCS) Authors. Please
submit your contributions electronically in PDF format to

For details on the LNCS style, see the Springer Author Instructions at NLP & DBpedia
2015 submissions are not anonymous.
