[Purpose/significance] Quality assurance is one of the most important procedures in web archiving, it runs throughout the whole web archiving work and affects the success odds of web archiving work. [Method/process] In this article, we made an analysis and comparative study for the quality assurance strategies of domestic and foreign web archiving organizations, and proposed a strategic theoretical framework for data quality assurance. [Result/conclusion] The framework in this article is a data-centered design, it includes a series of criteria and operating specifications, carries out data quality inspection throughout the collecting procedure by using semi-automatic auxiliary tools. Meanwhile, to ensure access to high quality archive data, the framework also takes team building, running environment maintenance and authorized backup to the websites as supplementary means.
