Source Code

Core implementation of the three experimental approaches: CF-only, IC-only, and IC+CF hybrid.

Files

  • permission_cf_only.py - Collaborative filtering baseline (LightGCN)
  • permission_ic_only.py - In-context learning baseline
  • permission_ic_cf.py - IC+CF hybrid (main contribution)
  • evaluation_utils.py - Shared evaluation utilities

Usage

Run scripts in order from the src/ directory:

# 1. CF only - Generates CF scores (no API key required)
python permission_cf_only.py

# 2. IC only - Requires OpenAI API key
python permission_ic_only.py

# 3. IC+CF - Requires OpenAI API key + CF scores from step 1
python permission_ic_cf.py

Requirements:

  • IC-only and IC+CF require OPENAI_API_KEY in .env file
  • All dependencies: pip install -r ../requirements.txt

Outputs

All results automatically saved to ../results/:

  • {method}_predictions.json - Test predictions
  • {method}_metrics.json - Performance metrics
  • cf_scores.csv - CF scores (required by IC+CF)

See ../results/README.md for details.
