INTERPRETATION (Landis & Koch, 1977)
======================================================================
Kappa Interpretation Scale:
< 0.00: Poor agreement
0.00-0.20: Slight agreement
0.21-0.40: Fair agreement
0.41-0.60: Moderate agreement
0.61-0.80: Substantial agreement
0.81-1.00: Almost perfect agreement ← BHT25 (κ = 0.829)
The corpus-wide weighted composite fluency was 4.13 ± 0.51."

KAPPA CALCULATION EXPLANATION
======================================================================
Fleiss' Kappa measures the degree of agreement among multiple raters
when assigning categorical ratings to a number of items.
Formula: κ = (P̄ - Pₑ) / (1 - Pₑ)
Where:
P̄ = Observed proportion of agreement among raters
Pₑ = Expected proportion of agreement by chance
For our dataset:
- 2,000 triplets rated by 4 annotators each
- 5-point Likert scale (ratings 1-5)
- κ = 0.83 means annotators agreed 83% more often than expected by chance
Example:
If all 4 annotators give rating '5': Perfect agreement (P = 1.0)
If ratings are 5, 5, 5, 4: High agreement (P ≈ 0.75)
If ratings are 5, 4, 3, 2: Low agreement (P ≈ 0.0)
The achieved κ = 0.829 falls in the 'Almost Perfect Agreement' category.
