15. Knowledge and Memory

What the system knows and remembers, across the scale from one turn to permanent. Children form a persistence gradient: short-term context → conversation memory → long-term/user/project memory → external stores (knowledge base, wiki, knowledge graph, ontology). The axis is lifespan and scope of retained information. The most structured, durable end of this spectrum is the ontology — which is what this very knowledge base is.

Children

  • short-term context
  • long-term memory
  • conversation memory
  • user memory
  • project memory
  • external knowledge base
  • LLM wiki
  • knowledge graph
  • ontology
  • RAG — how external knowledge is retrieved into context
  • Agents — agent memory
  • Artificial Intelligence — knowledge representation, the symbolic-AI ancestor
