Abstract: Big data has proven to contain invaluable information, and has become an indispensable part of the information structure for the advancement of our society. It is therefore critical for us to explore how big data can be further applied to maximize its value as an important source of information. However, as a side product of the information technology application, big data has demonstrated its complexity, uncertainty and emergence, which contribute to the difficulty of its application. In addition to the quality issues in common with traditional data, there are also a few problems that are specific to big data. To better utilize big data, this paper aims to serve as a preliminary study on the quality control of the application of big data, with three major sections: 1) a discussion on the definition of big data quality, what factors it is subject to and what potential quality issues it may have; 2) an introduction to the basic methodology of the quality control in big data application, explained from six perspectives, namely making theoretical preparations, building a quality control plan, attaching importance to studying small data, reinforcing big data management, advancing the training of big data personnnel and improving the legal framework for big data; and 3) a case studybased analysis of a number of things that entail particular attention in the application of big data.
