Improving Data Quality: Consistency and Accuracy. [PDF]
, 2007 This paper revisits the analysis of annotation propagation from source databases to views defined in terms of conjunctive (SPJ) queries. Given a source database D, an SPJ query Q, the view Q(D) and a tuple ΔV in the view, the view (resp. source) side-effect problem is to find a minimal set ΔD of tuples such that the deletion of ΔD from D results in the

Estimating Accuracy from Unlabeled Data
2018We consider the question of how unlabeled data can be used to estimate the true accuracy of learned classifiers. This is an important question for any autonomous learning system that must estimate its accuracy without supervision, and also when classifiers trained from one data distribution must be applied to a new distribution (e.g., document ...

The Accuracy of Demographic Data in the Ethiopian Censuses
Eastern Africa Social Science Research Review, 2017The quality of age-sex reporting and the presence of net undercount in the Ethiopian censuses were assessed using demographic analysis methods. First, to identify the presence of coverage errors, data organised by birth cohort for the three censuses (1984, 1994 and 2007) were graphically examined. Then age-specific sex ratios and cohort sex ratios were
