Temporal Knowledge Graph
Knowledge graph architecture where facts have validity windows showing when they became true and were superseded. Core component of Zep AI's Graphiti and other agent memory systems.
About this tool
Overview
Temporal Knowledge Graphs extend traditional knowledge graphs by tracking how facts change over time, with each fact having explicit time metadata showing its validity period.
Key Features
- Facts have validity windows (start time, end time)
- Historical relationships are preserved
- Temporal queries supported
- Evolution of knowledge tracked
- Time-aware reasoning enabled
Graphiti Implementation
Zep AI's Graphiti is a temporally-aware knowledge graph engine where every fact carries explicit time metadata. When an agent records an episode, Graphiti decomposes it into entities (nodes), relationships (edges), and temporal attributes.
Benefits for Agent Memory
- Track changing relationships ("Alice was project lead until January")
- Answer temporal queries ("Who managed the project in Q4?")
- Detect contradictions and updates
- Maintain historical context
- Support time-based reasoning
Performance
On LongMemEval benchmark, systems using temporal knowledge graphs like Graphiti achieved 63.8% with GPT-4o, showing strong improvements in temporal reasoning.
Use Cases
- AI agent memory systems
- CRM with relationship history
- Compliance tracking
- Medical records
- Project management
Pricing
Concept/architecture, Graphiti open-source.
