2017 January-June CSCI News Review
Data quality issues trace back their origin to the early days of computing. A wide range of domain-specific techniques to assess and improve data quality exist in the literature. However, these solutions primarily target data which resides in relational databases and data warehouses.
The emergence of big data and renaissance in machine learning challenges the suitability of database-centric approaches to data quality assessment. Minor data errors can cause major damage in Big Data applications. Damages manifest in various forms including loss of revenue, operational inefficiency, and regulatory compliance failure. Moreover, these errors cascade through downstream applications and exacerbate damages.
Machine Learning (ML)/ Artificial Intelligence (AI) brings to fore unique data quality issues. In addition to conventional data quality dimensions -- missing data, incomplete data, inconsistent data, inaccurate data, duplicate and dated data -- AI ushers in issues such as outliers, data imbalance, correlations between features, and curse of dimensionality. Gender bias in AI data is another big concern.
The goal of this workshop is to bring together data quality researchers and industry practitioners to share their ideas and best practices, identify and define important problems to further the field.
