Overall Certainty
Overall Certainty

This article explains how Rainbird calculates the overall "certainty factor" of an outcome, and how to use and interpret "certainty factors". It also gives you an example knowledge map to explore certainty factors inside the Rainbird Studio.

Any results that Rainbird produces after completing a query will have a “Certainty Factor”. The Certainty Factor represents how sure Rainbird is of the result it has returned. The Certainty Factor can vary depending on the data inputted by the user, the rules of a knowledge map, and whether Rainbird is working with incomplete data.

Data input into Rainbird is also associated with a certainty factor.  End-users can answer questions and provide a certainty level, which reflects how sure they are of their answer, during a query.  The knowledge map’s facts will also have a certainty factor associated with them, and whether Rainbird is more or less certain about a fact will impact the certainty factor of the results Rainbird produces.  

More information about how the certainty factor can be affected by end-users and facts can be found in the allowCF article and the Fact / Concept Instance articles.
