+**Quality-Related Domain Distribution**
 In order to explore the domain distribution across different quality intervals, we perform an analysis focusing on the quality-related domain distribution. Specifically, we calculate the proportions of various domains within each quality interval. As shown in Figure 5, this table provides a detailed breakdown of domain proportions across different quality intervals. From the results, we observe that the distribution of domain data within each quality interval aligns closely with their overall distribution in the dataset. Based on the proportions in Figure 5, researchers can filter domain-specific data within targeted quality intervals, enabling the extraction of higher-quality domain-specific data subsets.
