Evaluating the Completeness and Accuracy of MedWatch Data
American Journal of Therapeutics, 2014The Food and Drug Administration's MedWatch system--a voluntary surveillance program--received 600,000 adverse event reports on marketed drugs and devices in 2011. The Food and Drug Administration credits the MedWatch system with improving awareness, and expediting early detection, of drug and device risks and in illuminating the adoption of medical ...

On the accuracy of data sensing in the presence of mobility
2016 7th International Conference on the Network of the Future (NOF), 2016Smart Cities aim to improve living conditions by enabling new intelligent services for citizens. These services typically require environmental awareness obtained from distributed sensing systems. The implementation of such sensing systems on a city-wide scale is challenging, as the number of sensors needed can become unpractical.

Assessment of the accuracy of GeoNames gazetteer data
Proceedings of the 7th Workshop on Geographic Information Retrieval, 2013Gazetteers are the basis of many geospatial applications and serve an important role to collect and make available knowledge about the physical world such as place names and their coordinates. GeoNames is one of the largest and most often used gazetteer and it is generally assumed to be of sufficient quality.

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

The Impact of Data Accuracy on System Learning
Journal of Management Information Systems, 1993The purpose of this paper is to study the impact of database accuracy on system learning. The paper assumes a basic model of an information system with a database, a rulebase, and an embedded machine learning approach that is used to add rules to the rulebase.

Improving Data Quality: Consistency and Accuracy.
2007This 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
