Scientific Claim Verification (SciFact)

# Scientific Claim Verification (SciFact-style)
# Based on Wadden et al., EMNLP 2020
# Paper: https://aclanthology.org/2020.emnlp-main.609/
# Dataset: https://github.com/allenai/scifact
#
# This task verifies scientific claims against evidence from research abstracts.
# Annotators determine if a claim is SUPPORTED, REFUTED, or has NOT ENOUGH INFO
# based on the provided abstract, and identify which sentences provide evidence.
#
# Verification Labels:
# - SUPPORTS: The abstract provides evidence that the claim is true
# - REFUTES: The abstract provides evidence that the claim is false
# - NOT ENOUGH INFO: The abstract doesn't address the claim conclusively
#
# Annotation Guidelines:
# 1. Read the claim carefully and identify what it's asserting
# 2. Read the full abstract before making a judgment
# 3. Look for sentences that directly address the claim
# 4. SUPPORTS: Evidence confirms the claim (same finding)
# 5. REFUTES: Evidence contradicts the claim (opposite finding)
# 6. NOT ENOUGH INFO: Evidence is tangentially related but doesn't verify/refute
# 7. Mark ALL sentences that provide relevant evidence (rationales)
#
# Important Distinctions:
# - "No effect found" REFUTES claims of an effect
# - Correlation claims differ from causation claims
# - Population-specific findings may not generalize

  # Step 1: Verification label
  - annotation_type: radio
    name: verification
    description: "Based on the abstract, is the CLAIM supported, refuted, or is there not enough information?"
    labels:
      - "SUPPORTS"
      - "REFUTES"
      - "NOT ENOUGH INFO"
    tooltips:
      "SUPPORTS": "The abstract provides evidence that confirms the claim is true"
      "REFUTES": "The abstract provides evidence that contradicts the claim (claim is false)"
      "NOT ENOUGH INFO": "The abstract doesn't contain sufficient information to verify or refute the claim"

  # Step 2: Evidence/rationale identification
  - annotation_type: span
    name: evidence
    description: "Highlight the sentence(s) that provide evidence for your verification decision"
    labels:
      - "Evidence"
    label_colors:
      "Evidence": "#22c55e"
    tooltips:
      "Evidence": "Sentences that directly support or refute the claim"
    allow_overlapping: false

  # Step 3: Confidence
  - annotation_type: likert
    name: confidence
    description: "How confident are you in your verification?"
    min_value: 1
    max_value: 5
    labels:
      1: "Very uncertain"
      2: "Somewhat uncertain"
      3: "Moderately confident"
      4: "Confident"
      5: "Very confident"
