Rationale Annotation (ERASER)

# Rationale Annotation (ERASER-style)
# Based on DeYoung et al., ACL 2020
# Paper: https://aclanthology.org/2020.acl-main.408/
# Benchmark: https://www.eraserbenchmark.com
#
# Rationales are text spans that provide evidence for a classification decision.
# Good rationales should be:
# - SUFFICIENT: The rationale alone should support the label
# - NECESSARY: Removing the rationale should change the prediction
# - MINIMAL: Don't include extra context that isn't needed
#
# Annotation Guidelines:
# 1. First make the classification decision for the full text
# 2. Then identify which spans were most important for that decision
# 3. Ask: "If I only saw these spans, would I make the same decision?"
# 4. Ask: "If these spans were removed, would the label change?"
# 5. Prefer shorter, more precise spans over longer ones
# 6. Multiple separate rationales are okay
#
# Common Patterns:
# - For sentiment: words expressing opinion, emotion
# - For topics: key phrases indicating subject matter
# - For NLI: phrases showing contradiction or entailment

annotation_schemes:
  # Step 1: Make the classification
  - annotation_type: radio
    name: classification
    description: "What is the sentiment of this movie review?"
    labels:
      - "Positive"
      - "Negative"
    tooltips:
      "Positive": "The reviewer liked the movie (recommending it)"
      "Negative": "The reviewer disliked the movie (not recommending it)"

  # Step 2: Highlight rationales
  - annotation_type: span
    name: rationales
    description: "Highlight the text spans that JUSTIFY your classification (evidence)"
    labels:
      - "Rationale"
    label_colors:
      "Rationale": "#3b82f6"
    tooltips:
      "Rationale": "Spans that provide evidence for the classification. Should be sufficient (enough to justify label) and necessary (removing them would change the label)"
    allow_overlapping: false

  # Step 3: Rationale sufficiency check
  - annotation_type: radio
    name: sufficiency
    description: "Looking ONLY at your highlighted rationales, would you make the same classification?"
    labels:
      - "Yes, definitely"
      - "Probably yes"
      - "Uncertain"
      - "Probably no"
    tooltips:
      "Yes, definitely": "The rationales alone are completely sufficient"
      "Probably yes": "The rationales are mostly sufficient"
      "Uncertain": "Hard to tell from rationales alone"
      "Probably no": "More context would be needed"
