description: Sem-nCG (Semantic Normalized Cumulative Gain) Metric evaluates the quality of predicted sentences  (abstractive/extractive) in relation to reference sentences and documents using Semantic Normalized Cumulative Gain  (NCG). It computes gain values and NCG scores based on cosine similarity between sentence embeddings, leveraging a  Sentence-BERT encoder. This metric is designed to assess the relevance and ranking of predicted sentences, making it  useful for tasks such as summarization and information retrieval.
