8. A method for reducing user situation non-awareness associated with an automated dialogue system, the method comprising: receiving, by a processor, a user anticipated workload parameter; responsively to the user anticipated workload parameter, controlling the automated dialogue system to perform a system dialogue turn that reduces the user workload associated with interacting with the automated dialogue system, wherein the system dialogue turn includes a dialogue act selected from a group consisting of: a workload-reducing dialogue act; and a regular dialogue act modified by a workload-reducing modification; detecting a user situation non-awareness level for a plurality of dialogues stored in a database; responsive to detecting the user situation non-awareness level, computing a penalty value for assessing a dialogue quality according to at least the user situation non-awareness; and computing a dialogue policy for a controller of the automated dialogue system according to the database.
