Holistic data cleaning: Putting violations into context

Xu Chu, Ilyas, I. F., Papotti, P.·2013·2013 IEEE 29th International Conference on Data Engineering (ICDE)

Abstract

Data cleaning is an important problem and data quality rules are the most promising way to face it with a declarative approach. Previous work has focused on specific formalisms, such as functional dependencies (FDs), conditional functional dependencies (CFDs), and matching dependencies (MDs), and those have always been studied in isolation. Moreover, such techniques are usually applied in a pipeline or interleaved. In this work we tackle the problem in a novel, unified framework. First, we let users specify quality rules using denial constraints with ad-hoc predicates. This language subsumes existing formalisms and can express rules involving numerical values, with predicates such as “greater than” and “less than”. More importantly, we exploit the interaction of the heterogeneous constraints by encoding them in a conflict hypergraph. Such holistic view of the conflicts is the starting point for a novel definition of repair context which allows us to compute automatically repairs of better quality w.r.t. previous approaches in the literature. Experimental results on real datasets show that the holistic approach outperforms previous algorithms in terms of quality and efficiency of the repair.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
