STM can be viewed as a condensed
* short-term history of the input for a given user and data model. Every
submitted user request that wasn't
* rejected is added to the conversation STM as a list of tokens. Existing
STM tokens belonging to the same
* group will be overridden by the more recent tokens from the same group.
