TKG (Temporal Knowledge Graph)

Overview

TKG (Temporal Knowledge Graph) is a knowledge graph that manages timestamps. Unlike regular Knowledge Graphs, it tracks how facts evolve over time, enabling more accurate data management.

Why Temporal Information Matters

Facts change over time. For example:

• A company's CEO can change quarterly.
• Exchange rates fluctuate every second.
• Laws and regulations get amended.
• Research findings get revised with new discoveries.

How TKG Works

TKG assigns a valid time period to each fact.

• Valid From — When the fact became valid
• Valid Until — When the fact became invalid
• Recorded At — When the fact was recorded in the system

Benefits

• Accurate Verification — Verify facts as of a specific point in time.
• Change History Tracking — See the complete history of how facts have changed.
• Conflict Detection — Automatically detect conflicts between facts from different times.
