2nd Workshop on "The People's Web meets NLP: Collaboratively Constructed Semantic Resources"

Beijing August 28th, 2010 http://www.ukp.tu-darmstadt.de/scientific-community/coling-2010-workshop/

Keywords: Wikipedia, Wiktionary, Mechanical Turk, Games with a purpose, Folksonomies, Twitter, Social Networks

INTRODUCTION

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 [1], Wiktionary [2], Mechanical Turk [3], and game-based construction of semantic resources [4]. 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 [1]. 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 [5] or information extraction [6] have been proposed to guide the "crowds" while constructing resources of better quality.

TOPICS

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 extraction, etc.; * 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 resources; * Quality and reliability of collaboratively constructed semantic resources.

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.
