Horizon: Scalable Dependency-driven Data Cleaning
Summary: Horizon: scalable, dependency-driven FD repair. An end-to-end data-cleaning system that preserves the most frequent data patterns to boost accuracy, while delivering a linear-time repair algorithm that scales to millions of records and outperforms prior cleaners.
