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.
