METEOR (Metric for Evaluation of Translation with Explicit Ordering) 旨在改进 BLEU 的一些缺点。它不仅考虑了精确率和召回率,还引入了 WordNet 中的同义词和词干信息,并对 n-gram 的连续匹配进行了加权,从而更好地衡量生成文本的流畅性。 优缺点: BLEU 和 ROUGE 的优点在于易于计算、自动化程度高,且在一定...
Accuracy is a widely used metric forclassification tasks, representing the proportion of correct predictions made by the model. While this is a typically intuitive metric, in the context of open-ended generation tasks, it can often be misleading. For instance, when generating creative or contextuall...

Potential of HybridRAG: Depending on the dataset and context injection, HybridRAG has shown potential to outperform traditional VectorRAG on nearly every metric. Its graph-based retrieval capabilities enable the improved handling of complex data relationships, although this may result in a slight trade...

While there has been significant development of models for Plain Language Summarization (PLS), evaluation remains a challenge. PLS lacks a dedicated assessment metric, and the suitability of text generation evaluation metrics is unclear due to the unique transformations involved (e.g., adding back...
Our analysis shows that the MQA-metric outperforms traditional metrics like BLEU, ROUGE and METEOR. Unlike existing metrics, MQA-metric leverages semantic comprehension through large language models (LLMs), enabling it to capture contextual nuances and synonymous expressions more effectively. This ...
