NLG Evaluation Framework

An NLG Evaluation Framework is an evaluation framework that provides structured methodology for assessing NLG system performance through multiple evaluation methods and quality dimensions.

• AKA: Natural Language Generation Evaluation Framework, NLG Assessment Framework, Text Generation Evaluation Framework, Generation Quality Framework.
• Context:
  • It can typically combine Automatic Evaluation Metrics with Human Evaluation Methods.
  • It can typically assess Multiple Quality Dimensions including semantic aspects and style aspects.
  • It can often incorporate Reference-Based Evaluation and Reference-Free Evaluation.
  • It can often support Task-Specific Customization for different NLG tasks.
  • It can integrate Statistical Significance Testing for robust comparisons.
  • It can provide Evaluation Protocol Guidelines ensuring reproducibility.
  • It can enable Multi-Level Evaluation from token-level to document-level.
  • It can facilitate Cross-System Comparison through standardized metrics.
  • It can range from being a Lightweight NLG Evaluation Framework to being a Comprehensive NLG Evaluation Framework, depending on its evaluation coverage.
  • It can range from being a Domain-Specific NLG Evaluation Framework to being a Domain-Agnostic NLG Evaluation Framework, depending on its application scope.
  • It can range from being a Static NLG Evaluation Framework to being an Adaptive NLG Evaluation Framework, depending on its evolution capability.
  • It can range from being a Single-Language NLG Evaluation Framework to being a Multilingual NLG Evaluation Framework, depending on its language support.
  • ...
• Examples:
  • General NLG Evaluation Frameworks, such as:
    • GEM Evaluation Framework for comprehensive assessment.
    • GENIE Framework for human-centric evaluation.
    • BERTScore Framework for neural evaluation.
  • Task-Specific Frameworks, such as:
    • SummEval Framework for summarization evaluation.
    • WMT Metrics Framework for translation assessment.
    • DialogEval Framework for dialogue evaluation.
  • Component Frameworks, such as:
    • Semantic Evaluation Framework for meaning assessment.
    • Diversity Evaluation Framework for output variety.
  • ...
• Counter-Examples:
  • Single-Metric Evaluation, which lacks comprehensive assessment.
  • Ad-hoc Evaluation Method, which lacks systematic structure.
  • Training Framework, which focuses on model development.
