Toward a view-based data cleaning architecture

Abstract

Big data analysis has become an active area of study with the growth of machine learning techniques. To properly analyze data, it is important to maintain high-quality data. Thus, research on data cleaning is also important. It is difficult to automatically detect and correct inconsistent values for data requiring expert knowledge or data created by many contributors, such as integrated data from heterogeneous data sources. An example of such data is metadata for scientific datasets, which should be confirmed by data managers while handling the data. To support the efficient cleaning of data by data managers, we propose a data cleaning architecture in which data managers interactively browse and correct portions of data through views. In this paper, we explain our view-based data cleaning architecture and discuss some remaining issues.
