Evidence Alignment Evaluation Task

An Evidence Alignment Evaluation Task is an evaluation task that is an explainability assessment task measuring the alignment quality between human-annotated evidence spans and system-identified spans.

• AKA: Span Alignment Assessment Task, Evidence Correspondence Task.
• Context:
  • It can typically require Human Evidence Annotations as gold standard.
  • It can typically assess Span Overlap at various granularitys.
  • It can typically evaluate Semantic Equivalence beyond exact match.
  • It can typically measure Coverage Completeness of important evidence.
  • It can typically identify Alignment Patterns across model types.
  • ...
  • It can often employ Multiple Annotators for reliability.
  • It can often use Flexible Matching Criteria for partial credit.
  • It can often incorporate Importance Weighting for critical spans.
  • It can often analyze Systematic Biases in evidence selection.
  • ...
  • It can range from being a Token-Level Alignment Task to being a Sentence-Level Alignment Task, depending on its evaluation granularity.
  • It can range from being a Strict Alignment Task to being a Relaxed Alignment Task, depending on its matching criteria.
  • ...
  • It can evaluate Explainable NLP Systems for evidence quality.
  • It can be solved by an Evidence Alignment Evaluation System.
  • It can produce Evidence Alignment Metrics as output.
  • It can support Model Comparison for interpretability.
  • ...
• Example(s):
  • Rationale Alignment Tasks comparing with human rationales.
  • Attention Alignment Tasks validating attention weights.
  • Evidence Sufficiency Tasks testing span completeness.
  • Cross-Model Alignment Tasks comparing different systems.
  • Domain-Specific Alignment Tasks for specialized fields.
  • ...
• Counter-Example(s):
  • Output Quality Tasks, which evaluate final result not evidence.
  • Efficiency Evaluation Tasks, which measure speed not alignment.
  • User Satisfaction Tasks, which assess preference not correctness.
