CerFix: A System for Cleaning Data with Certain Fixes
The authors present CerFix, a data cleaning system that finds certain fixes for tuples at the point of data entry, i.e., fixes that are guaranteed correct. It is based on master data, editing rules and certain regions. Given some attributes of an input tuple that are validated (assured correct), editing rules tell users what other attributes to x and how to correct them with master data. A certain region is a set of attributes that, if validated, warrant a certain x for the entire tuple.
