Taxonomy of Information Retrieval Models

IR Models
Over the years, alternative modeling paradiagms for several classic models have been proposed:

• Adhoc:
  • Boolean
    • Fuzzy
    • Extended Boolean
  • Vector
    • Generalized Vector
    • Latence Semantic Index
    • Neural Networks
  • Probabilistic
    • Inference Network
    • Belief Network
• Filtering:
  • Non-Overlapping Lists
  • Proximal Nodes
