数据集质量评估:基于类比的工作量估计的扩展

Dataset Quality Assessment: An extension for analogy based effort estimation

Mohammad Azzeh

摘要:

类比估算(EBA)是软件工程领域中一种日益活跃的研究方法。该方法的基本假设是,属性值方面的相似项目在努力值方面也将相似。众所周知,软件数据集的质量对这种方法的可靠性和准确性有相当大的影响。因此,如果软件数据集不满足上述假设,那么它对于EBA方法不是很有用。本文提出了一种新的方法,基于肯德尔的行秩相关,使数据质量的评估,并提供了一个数据预处理阶段的EBA。该方法为数据质量评价过程提供了良好的统计基础和依据。与Analogy-X不同,我们的方法能够单独处理分类属性,而无需对数据集进行分区。实验结果表明,该方法可以形成一个有用的扩展EBA,因为它使:数据集质量评估,属性选择和识别异常观测。

英文摘要:

Estimation by Analogy (EBA) is an increasingly active research method in the area of software engineering. The fundamental assumption of this method is that the similar projects in terms of attribute values will also be similar in terms of effort values. It is well recognized that the quality of software datasets has a considerable impact on the reliability and accuracy of such method. Therefore, if the software dataset does not satisfy the aforementioned assumption then it is not rather useful for EBA method. This paper presents a new method based on Kendall's row-wise rank correlation that enables data quality evaluation and providing a data preprocessing stage for EBA. The proposed method provides sound statistical basis and justification for the process of data quality evaluation. Unlike Analogy-X, our method has the ability to deal with categorical attributes individually without the need for partitioning the dataset. Experimental results showed that the proposed method could form a useful extension for EBA as it enables: dataset quality evaluation, attribute selection and identifying abnormal observations.
