Here we are measuring the volatility of Google's Knowledge Graph . The data clearly shows periodic data refreshes or algorithm updates - almost certainly both.

How are we Measuring Knowledge Graph Changes?

We have a system that tracks the confidence score returned by the Knowledge Graph API on a dataset of several thousand known Entities. We have isolated the three 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. Shift: How significant the change was to the overall score (scale/depth).
The graph below shows Magnitude (Volatility) in purple, and Shift in red. Amplitude is a measurement we are using internally as part of the paid Kalicube Pro platform and won’t be adding that publicly in the foreseeable future.
