Knowledge Graph Sensor
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:
- Magnitude: How many entities saw an increase or decrease (reach/breadth).
- Amplitude: How significant that change, in confidence scores of the affected entities, was on a micro-level (scope/height).
- Shift: How significant the change was to the overall score (scale/depth).
