4Allergy modeling issues
  1. Allergy to combination substances




  2. Allergy to material agents
  • Inadequacy of the current model in which allergy to x and y is subsumed by allergy to x and allergy to y and proposed model in which allergy to x and y is modeled using GCIs resulting in allergy to x and allergy to y being subsumed by allergy to x and y discussed
  • Allergy to combined substances should be modeled as allergy to combination products
  • A model for allergy to products will be developed dependent on new models for substances and products
  • Allergy to material agents including physical objects and living organisms should have a causative agent relationship to a substance derived from the material agent
