Metric: bertscore
Update on GitHub


BERTScore leverages the pre-trained contextual embeddings from BERT and matches words in candidate and reference sentences by cosine similarity. It has been shown to correlate with human judgment on sentence-level and system-level evaluation. Moreover, BERTScore computes precision, recall, and F1 measure, which can be useful for evaluating different language generation tasks. See the `` file at []( for more information.

How to load this metric directly with the datasets library:

from datasets import load_metric
metric = load_metric("bertscore")
