Abstract
Multiple goals in spoken dialogues are usual situations in everyday life.
For example, when you want to book a train seat, you often ask for the
return ticket in the same utterance. This phenomenon is however not taken into
account by current dialogue systems. I propose a model allowing the efficient
management of those situations.
For example, when you want to book a train seat, you often ask for the
return ticket in the same utterance. This phenomenon is however not taken into
account by current dialogue systems. I propose a model allowing the efficient
management of those situations.
A situation of multiple goals occurs as soon as the user utters a new goal
whereas the previous one has not been solved yet. We propose an algorithm to
identify the kind of multiple goals according to the task state and to the
goals themselves. I define ten strategies to process those situations. Three
meta-strategies order the strategies relevant for given situations. The system
checks the preconditions of strategies to be sure they can be triggered.
When a strategy is applied, the system updates the dialogue history and the
task state. Some strategies push a goal in a stack and pop it when the
first processed goal is fully reached.
