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
