Task: Question Answering
Input (English): We showed in BIBREF22 that Pearson correlation is badly suited for STS. Instead, we compute the Spearman's rank correlation between the cosine-similarity of the sentence embeddings and the gold labels. 
 Question: What metrics are used for the STS tasks?
Output (English):  Spearman's rank correlation between the cosine-similarity of the sentence embeddings and the gold labels
