Federation Service

Controls how the Federation Service filters and ranks results across connected bots in a Universal bot deployment.

The Settings > Configuration > Federation Service configurations control how the Federation Service aggregates and ranks responses from connected bots in a Universal bot deployment. These are tenant-level settings that apply to all Universal bots in your Aisera tenant.

Result ranking and filtering

Number of results to be returned

Type	Integer
Default	5

Sets the maximum number of results the Federation Service returns after aggregating and ranking responses from all connected bots. The Federation Service sorts results by confidence score and applies this limit to the combined pool after filtering by Result Threshold. Increase this value when your deployment uses many federated bots and you want the system to consider more candidates before selecting a response; decrease it to reduce noise when precision matters more.

Result Threshold

Type	Decimal
Default	0.8

Sets the minimum confidence score a result must strictly exceed to be included in the Federation Service response. The Federation Service discards results at or below this value before ranking and applies the Number of results to be returned cap. Increase this value to filter out low-confidence matches. Decrease it if the system is consistently excluding valid matches.

The threshold comparison is strict. A result scoring exactly equal to the threshold is excluded. For example, a result with a confidence score of 0.8 is discarded when the threshold is set to 0.8.
