In this paper we present a method for integrating confidence scores into the understanding and dialogue components of a speech understanding system. The understanding component of our system receives an n-best list of recognition hypotheses augmented with word-level confidence scores. The confidence scores are used by the understanding component to hypothesize when words in a recognizer’s n-bes...

In interactive systems, the ~dialogue manager’ isa central component, whose primary task is to decide what o do next in a dialogue. This decision i volves taking a variety ofkinds of context information nto account, with different logical properties, u ed in different types of reasoning, andtherefore with different demands onrepresentation. In this paper we discuss the representation of the con...

A challenge in dialogue act recognition is the mapping from noisy user inputs to dialogue acts. In this paper we describe an approach for re-ranking dialogue act hypotheses based on Bayesian classifiers that incorporate dialogue history and Automatic Speech Recognition (ASR) N-best information. We report results based on the Let’s Go dialogue corpora that show (1) that including ASR N-best info...

This paper introduces Flipper, an specification language and interpreter for Information State Update rules that can be used for developing spoken dialogue systems and embodied conversational agents. The system uses XML-templates to modify the information state and to select behaviours to perform.

i am delighted to announce completion of the second issue of the new journal of “geopersia”, a product of the new era of replacing the persian language journals with specific english-language ones. our purpose is to provide a journal that offers a multi-disciplinary analysis of issues concerning geology subjects (i.e. sedimentology, stratigraphy, paleontology, petroleum geology, engineering geo...

This paper summarizes the latest, final version of ISO standard 24617-2 “Semantic annotation framework, Part 2: Dialogue acts”. Compared to the preliminary version ISO DIS 24617-2:2010, described in Bunt et al. (2010), the final version additionally includes concepts for annotating rhetorical relations between dialogue units, defines a full-blown compositional semantics for the Dialogue Act Mar...

We reene and extend prior views of the description , purposes, and contexts-of-use of acknowledgment acts through empirical examination of the use of acknowledgments in task-based conversation. We distinguish three broad classes of acknowledgments (other!ackn, self!other!ackn, and self+ackn) and present a catalogue of 13 patterns within these classes that account for the spe-ciic uses of acknow...

A Spoken Dialogue System provide is a computer system able to converse with human with human voice. Dialogue Manager is a component of SDS that manages state of dialogue and dialogue strategy. This report presents the literature survey based on DM. The papers are based on various components of DM. The components of DM are dialogue representation, belief state representation, policy optimization...

This paper presents an update semantic for dialogue acts, defined in terms of combinations of very simple ‘elementary update functions’. This approach allows fine-grained distinctions to be made between related types of dialogue acts, and relations like entailment and exclusion between dialogue acts to be established. The approach is applied to dialogue act representations as defined in the Dia...
