2nd Workshop on
"The People's Web meets NLP:
Collaboratively Constructed Semantic Resources"
August 28th, 2010
Wikipedia, Wiktionary, Mechanical Turk, Games with a purpose,
Folksonomies, Twitter, Social Networks
The workshop builds upon the success of the first ACL "The People's Web
meets NLP" Workshop in 2009 that attracted 21 submissions. Accepted
submissions included papers on Wikipedia , Wiktionary , Mechanical
Turk , and game-based construction of semantic resources . This
clearly demonstrates a substantial and growing interest of the NLP
community in collaboratively constructed semantic resources (CSRs),
also evidenced by the increasing number of publications in this area
and the EMNLP 2009 Web 2.0 track. In many works, CSRs have been used
to overcome the knowledge acquisition bottleneck and coverage problems
pertinent to conventional lexical semantic resources. The greatest
popularity in this respect can so far certainly be attributed to
Wikipedia . However, other resources, such as folksonomies or the
multilingual collaboratively constructed dictionary Wiktionary, have
also shown great potential. Thus, the scope of the workshop deliberately
includes any collaboratively constructed resource, not only Wikipedia.
Effective deployment of CSRs to enhance NLP introduces a pressing need
to address a set of fundamental challenges, e.g. the interoperability
with existing resources, or the quality of the extracted lexical
semantic knowledge. Interoperability between resources is crucial as
no single resource provides perfect coverage. The quality of CSRs is
a fundamental issue, as they lack editorial control and entries are
often incomplete. Thus, techniques for link prediction  or
information extraction  have been proposed to guide the "crowds"
while constructing resources of better quality.

The workshop will bring together researchers from different worlds, for
example those using collaboratively constructed resources as sources of
lexical semantic information for NLP purposes such as information
retrieval, named entity recognition, or keyword extraction, and those
using NLP techniques to improve the resources or extract and analyze
different types of lexical semantic information from them. We will
especially welcome contributions of interdisciplinary nature, e.g. those
applying discourse analysis techniques from computational linguistics to
the content of CSRs to better understand their properties.
Specific topics include but are not limited to:
* Analysis of collaboratively constructed resources, such as wiki-based
platforms, folksonomies, Twitter, or social networks;
* Using collaboratively constructed resources for NLP purposes such
as information retrieval, text categorization, information
* Using special features of collaboratively constructed resources to
create novel resource types, for example revision-based corpora,
simplified versions of resources, etc.;
* Analyzing the structure of collaboratively constructed resources
related to their use in NLP;
* Interoperability of collaboratively constructed resources with
conventional lexical semantic resources and between themselves;
* Mining social and collaborative content for constructing structured
semantic resources and the corresponding tools;
* Mining multilingual information from collaboratively constructed
* Quality and reliability of collaboratively constructed semantic
We especially encourage short papers describing publicly available tools
for accessing or analyzing collaboratively constructed resources that can
serve as a multiplier in the NLP community.
The workshop is intended to be highly interdisciplinary. Thus, we encourage
the participation of researchers working on computational linguistics
aspects (e.g. parsing or discourse analysis) or NLP applications (e.g.
information retrieval, information extraction, question answering, and
knowledge representation) as well as researchers from other areas who
might benefit from collaboratively constructed semantic resources.
Substantially extended versions of the best papers from the workshop can
be submitted to a planned Special Issue in one of the major computational
linguistics journals. The revised papers will have to undergo a separate
reviewing process required for journal publications.
