Query: Is "my favorite new movie" my favorite movie? Probing the Understanding
  of Recursive Noun Phrases   Recursive noun phrases (NPs) have interesting semantic properties. For
example, "my favorite new movie" is not necessarily "my favorite movie",
whereas "my new favorite movie" is. This is common sense to humans, yet it is
unknown whether pre-trained language models have such knowledge. We introduce
the Recursive Noun Phrase Challenge (RNPC), a challenge set targeting the
understanding of recursive NPs. When evaluated on our dataset, state-of-the-art
Transformer models only achieve around chance performance. Still, we show that
such knowledge is learnable with appropriate data. We further probe the models
for relevant linguistic features that can be learned from our tasks, including
modifier semantic category and modifier scope. Finally, models trained on RNPC
achieve strong zero-shot performance on an extrinsic Harm Detection task,
showing the usefulness of the understanding of recursive NPs in downstream
applications. All code and data will be released at
https://github.com/veronica320/Recursive-NPs.
