Semantic Specificity in Spoken Dialogue Requests
Ben Hixon, Rebecca J. Passonneau, Susan L. Epstein · 2012
Ambiguous or open-ended requests to a dialogue system result in more complex dialogues. We present a semantic-specificity metric to gauge this complexity for dialogue systems that access a relational database. An experiment where a simulated user makes requests to a dialogue system shows that semantic specificity correlates with dialogue length. 1
