Abstract

A frequent difficulty faced by developers of Dialogue Systems is the absence of a corpus of conversations to model the dialog statistically. Even when such a corpus is available, neither an agenda- nor a statistically-based dialog control logic are options if the domain knowledge is broad. This paper presents a module that automatically generates system-turn utterances to guide the user through the dialog. These system-turns are not established beforehand, and vary with each dialog. The module is valid for agenda-based and statistical approaches, being applicable in both types of corpora. Particularly, the task defined in this paper is the automation of a call-routing service. The proposed module is used when the user has not given enough information to route the call with high confidence. Doing so, and using the generated system-turns, the obtained information is improved through the dialog. The paper focuses on the development and operation of this module.
