Hierarchical or nested annotation of linguistic data often co-exists with simpler non-hierarchical or ﬂat counterparts, a classic example being that of annotations used for parsing and chunking. In this work, we propose a general strategy for comparing across these two schemes of annotation using the concept of entailment that formalizes a correspondence between them. We use crowdsourcing to obtain query and sentence chunking and show that entailment can not only be used as an effective evaluation metric to assess the quality of annotations, but it can also be employed to ﬁlter out noisy annotations.
