Note: Google has multiple Knowledge Graphs. Here we are measuring Google's Main Knowledge Graph / Knowledge Vault.

How are we Measuring Knowledge Vault Changes?

We have a system that tracks the number of related entities, the confidence score returned by the Knowledge Graph API and several other data points on a dataset of 6,000 names: 2,000 long-running US baseline names plus 4,000 US mid-market entrepreneurs and their companies. We have isolated three insightful aspects of these changes and measure them daily. We measure:

  1. Magnitude: How many entities saw an increase or decrease (reach/breadth).
  2. Amplitude: How significant that change, in confidence scores of the affected entities, was on a micro-level (scope/height).
  3. Size: How many entities the Knowledge Vault contains.
The graph below shows Magnitude (Volatility) in purple, and Size in red. We are using amplitude and many other measurements internally as part of the paid Kalicube Pro platform and won’t be adding that publicly in the foreseeable future.
