Entities that answer questions are organized into entity groups. An interface determines an answer to a question from one of the entity groups with a confidence that is greater than a second confidence threshold. To determine the answer, the interface performs an exploration phase where the interface asks the question to each of the entity groups. Entity groups that provide answers with a confidence that is greater than a first confidence threshold are selected for a subset. The interface enters an exploitation phase where the question is asked of the entity groups in the subset. If an answer is determined with a confidence that is greater than the second confidence threshold, then the answer is provided. If no answer is determined before a duration of time expires, then the interface enters a rollback phase where all of the entity groups are considered. |
