Knowledge Graphs as Dynamic Memory Substrate

The knowledge graph is evolving from static repository to dynamic memory substrate that continuously adapts to agent interactions.

Traditional KGs stored knowledge for human interpretation, structured, queryable, but fundamentally stable. The emerging pattern treats KGs as persistent, structured memory for autonomous systems, growing, reorganizing, and updating in response to what the agent learns and does.

This reframes what KG “quality” means. It’s not just about accuracy and coverage at construction time. It’s about temporal coherence (tracking when facts were valid), continuous integration (absorbing new information without full reconstruction), and support for self-reflective reasoning (the agent can query its own memory to understand what it knows and doesn’t know).

The shift parallels how human expertise works: not a fixed knowledge store, but an evolving understanding that adapts based on ongoing experience.
