你的段落整体表达得很好，但可以进行一些小的调整以增强流畅性和清晰度。以下是经过修正的版本：
SCSCL shows good clustering performance on all four benchmark datasets, particularly on the Kipris dataset, where it achieves optimal ACC and NMI. It also demonstrates optimal ACC on the AgNews dataset and the StackOverflow dataset; however, its NMI is not as favorable as that of SCCL. This discrepancy might be due to fewer training samples in the AgNews dataset and a larger number of clusters in the StackOverflow dataset. In the Tweeter dataset, which has the least training samples and the most clusters, HAC-SD exhibits the best ACC while SCCL shows the highest NMI. Therefore, we conclude that the concise contrastive learning framework SimCSE can highlight the advantages of instance discriminative contrastive learning in clustering and generally yields better clustering results on datasets with a large number of training samples, fewer clusters, and a higher average number of words per text.
主要修改点：
- 使用“particularly”替换“especially”使句子更为正式。
- 对某些句子结构进行了简化，使逻辑更加清晰。
- 修改了一些措辞，以增强专业性和连贯性。
