This MegaAcceptability dataset consists of ordinal acceptability judgments for 1,000 clause-embedding verbs of English in 50 surface-syntactic frames and three matrix tenses. This dataset combines the MegaAcceptability version 1.0 and new data collected on Amazon’s Mechanical Turk using Ibex on Mechanical Turk.

For a detailed description of the dataset, the item construction and collection methods, and discussion of how to use a dataset on this scale to address questions in linguistic theory, please see the following papers:
