- Reflexive (cache): abstract...abstract
- Symmetric (trigger): abstract...art implies
abstract...art and art...abstract
- Transistive (LSA): abstract...art and art...artist

Neural network model of LSA
- Layer 1: 20K-60K words
- Layer 2: 200-1000 semantic categories (2 shown above)
- Layer 3: 20K-100K documents or text windows
