Abstract
Systems and methods discussed herein generate a semantic-domain constraint corpus that detects data errors within columns of any data table, without requiring domain-experts to manually specify constraints on a per-table basis. A large body of semantic-domain constraint candidates is generated from test datasets, after which high-quality constraints within those candidates are identified. The systems and methods further pare the remaining semantic-domain constraints down based on size and false-positive rate constraints. The resulting semantic-domain constraint corpus can be applied to any structured dataset to automatically detect errors within columns of that dataset.
