<br/><br/> Currently, there are two main basic strategies to resolve conflicts in data integration: Instance-based strategy and metadata-based strategy. In a metadata-based strategy, the data integration administrator uses some features of source. One of the most important features in metadata-based strategy is source accuracy, which is concerned with the correctness with which real world data to what is in data source. However, it is difficult to calculate accuracy for all data sources by comparing data about objects with what is in real world, so that we propose a method to select one source as a reference and propose a new way to approximate sources accuracy using reference source accuracy
