| Abstract: | Thinking of the different importance between quality features and attributes in tables, a data quality assessment algorithm based on weight was proposed. This algorithm highlights the impact of the important attributes and quality features to the overall quality of system, and assesses the data quality of the existing system more scientifically. The algorithm in the actual data quality assessment system has been applied and the results show that the proposed algorithm can improve the accuracy of the assessment. |
