A decision rule method for data quality assessment

The assessment of data quality is a key success factor for organisational performance. It supports managers and executives to clearly identify and reveal defective data in their information systems, and consequently minimises and eliminates the risks associated with decisions based on poor data. Despite the importance of data quality assessment, limited research has been conducted on providing ...

A method for interoperable digital libraries and data repositories

Aside from the basic importance of metadata in documenting, the characteristics of data for reuse is the fundamental role it plays in the functioning of digital libraries and data repositories. Metadata provides both the content of the search catalogs and provides part of the basis for performing quality control on the source data. In this paper, we describe a method for a scalable and decentra...

Toward a quality assessment framework for knowledge-based systems

Data quality evaluation and improvement for prognostic modeling using visual assessment based data partitioning method

When developing Prognostic and Health Management (PHM) applications for manufacturing systems, data acquired frequently comes with issues which hinder further data analysis. However, there is neither a clear definition of the data quality nor evaluation methods to quantify if acquired data is suitable for these prognostic modeling tasks such as failures detection, diagnosis and prediction. Espe...
