As an added bonus...

• Incomplete lattices

  • No top level (no universal visibility)
    • Approach:
      • Add dummy top level and run as before
      • If an object is labeled at top, no visibility
    • No bottom level (no unclassified data)
      • Approach:
        • Add dummy bottom level and run as before
        • If an object is labeled at bottom, there was no effective constraint on that object’s classification
