Just to whet your appetite, here is the abstract:

The task of classifying English noun compounds explores the idea of 
interpreting the semantics of noun compounds via paraphrases. Given a 
two-word noun compound, the participants are asked to produce an 
explicitly ranked list of its free paraphrases. The list will be 
automatically compared and evaluated against a similarly ranked list of 
paraphrases proposed by human annotators, recruited and managed through 
Amazon's Mechanical Turk. The comparison of raw paraphrases will be 
sensitive to syntactic and morphological variations. The ranking of 
paraphrases will be based on their relative popularity among annotators. 
To achieve a reliable ranking, highly similar paraphrases will be 
grouped so as to downplay superficial differences in syntax and morphology.

And the relevant dates (slightly tentative), all in 2013:

February 15: Test set ready
February 15: Registration deadline for task participants
March 1-15: Evaluation period
April 9: Paper submission deadline
May 4: Camera-ready paper due
