hey will, the metrics in the scoring system are not predefined but rather generated for a use case by breaking down a subjective set of conditions into a tree of metrics that combine various objective metrics into a subjective aggregate. Here is a prefilled playground with dimensions for the sentiment analysis in customer reviews use case. You can see how it breaks down and if you put a review and click Run you should see the scores combine from individual custom dimensions to the aggregate score. Hope this helps!
