In general there are certain aspects that need to be defined in order for speech acts to be used in dialogue management.
In general there are certain aspects that need to be defined in order for speech acts to be used in dialogue management.
Precise definitions of every speech act are needed. That involves conditions specifying what counts as a speech act of a particular kind. It also involves enumerating effects that a speech act has for the dialogue state, the mental state of the participants, the task, where applicable, or whatever area in a domain speech acts can bring a change about.
Recognition criteria are also necessary. Speech act definitions utilise, to a large extent, the mental state of the participants, which is not directly observable. This might render the conditions specified insufficient for the recognition of speech acts. In that case, different recognition criteria need to be defined or the definitions need to be enriched and augmented to enable robust recognition.
Planning schemes must be defined as well. These should encompass the top level of how far into the dialogue the system should plan. That means, deciding if planning the speech acts of the next utterance is enough, or if planning further ahead is necessary for better communication. The other level to be considered is that which connects whatever it is to be communicated with the realisation that achieves that aim.
Last but not least, the role of speech acts itself in dialogue management must be clear. If speech acts are only the means of communication and not the object of communication, then an object, as well as its relation to speech acts must be defined. So far, intentions have been commonly assumed to be the object to be communicated (See Section 3.4.9).
