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 June 13 or 14 [TBC]: Workshop co-located with NAACL
