【摘要】 针对数据集成过程中存在异常数据的问题,提出了加速度趋势比较清洗方法,即比较数据集成过程中某些字段的变化趋势来发现数据的异常。通过加速度趋势比较清洗,提高了数据集成的异常记录检测,改变了数据集成过程中的数据质量,增强了数据的可利用性。最后给出了具体算法的描述。更多还原

【Abstract】 In light to the issue of outliers in data integration process,we put forward the accelerating trend comparison cleansing method in this paper,namely it finds the outliers by comparing the trend of changes in a certain field during the data integration process.The accelerating trend comparison cleansing meliorates the detection of outliers’ record in data integration,and improves data quality when data is integrating so that the reusability of the data is enhanced.At the end of this article,it gives a specific description of the algorithm details.更多还原
