背景：NASA数据集以前曾被广泛用于软件缺陷的研究。在2013年Shepperd等人。提出了一套基本的规则，用于删除错误的数据从美国宇航局的数据集，使这些数据更可靠的use.Objective：我们现在已经找到了必要的额外的规则，用于删除有问题的数据，这是没有确定的Shepperd等人。结果：在本文中，我们证明了错误的数据仍然存在，即使使用Shepperd等人清洗后的水平。的规则，并应用我们的新规则，以消除这些错误的数据。结论：即使在系统的数据清理NASA MDP数据集，我们发现新的错误数据。研究人员在使用数据之前应始终明确考虑数据质量。
Background:The NASA datasets have previously been used extensively in studies of software defects. In 2013 Shepperd et al. presented an essential set of rules for removing erroneous data from the NASA datasets making this data more reliable to use.Objective:We have now found additional rules necessary for removing problematic data which were not identified by Shepperd et al.Results:In this paper, we demonstrate the level of erroneous data still present even after cleaning using Shepperd et al.'s rules and apply our new rules to remove this erroneous data.Conclusion:Even after systematic data cleaning of the NASA MDP datasets, we found new erroneous data. Data quality should always be explicitly considered by researchers before use.
