METEOR

What is METEOR?

METEOR (Metric for Evaluation of Translation with Explicit ORdering) is a metric used to evaluate the quality of machine-translated text by comparing it to human-written reference translations. Unlike BLEU, METEOR focuses on recall and uses semantic matching, synonym handling, and stemming to provide a more comprehensive evaluation of translation quality.

Why is it Important?

METEOR is crucial for assessing the performance of machine translation and natural language generation systems. It improves upon traditional metrics by incorporating linguistic nuances, resulting in a more accurate and human-like evaluation of text quality. This makes it especially valuable for applications that require high-quality language output.

How is This Metric Managed and Where is it Used?

METEOR is calculated by matching words in the generated text to the reference text using exact matches, synonyms, and stems. The metric also accounts for word order and assigns penalties for misaligned outputs. It is widely used in machine translation, text summarization, and content generation tasks.

Key Elements

  • Semantic Matching: Identifies synonyms and stems to evaluate translation quality.
  • Recall-Oriented: Prioritizes capturing all relevant information over precision.
  • Word Order Penalty: Accounts for structural differences between generated and reference texts.
  • Alignment Scoring: Measures how closely the two texts align at a linguistic level.
  • Linguistic Features: Includes semantics and syntax for a holistic evaluation.
