Cleaning Method of Incorrectness Data Based on Outlier Detection
基于孤立点检测的错误数据清理方法

Aiming at incorrectness data appeared in data source,the importance of outlier detection method in data cleaning is analyzed, and an incorrectness data cleaning method based on outlier detection is proposed. Based on analyzing the common outlier detection method, an effective outlier detection method is used to detect the outliers in data source. Finally, the validity of this method is proved by an example. Research result shows that incorrectness data cleaning method based on outlier detection can detect incorrectness data of data source effectively.
