In this paper, we introduce a method of generating a prosodic tree structure from the F0 contour of an utterance in order to analyze the information expressed by prosody in Japanese spontaneous dialogue. The connection rate, which means the strength of the relationship between two prosodic units, is de ned. By repeatedly combining the two adjacent prosodic units where the rate is high, the tree...

A novel approach for introducing adaptivity to user satisfaction into dialogue management is presented in this work. In general, rendering the dialogue adaptive to user satisfaction enables the dialogue system to improve the course of the dialogue or to handle problematic situations better. In this contribution, the theoretical aspects of rendering the dialogue cycle adaptive are outlined. Furt...

Conversational Language Understanding (CLU) is a key component of goal oriented dialogue systems that would parse user utterances into semantic frame representations. Traditionally CLU does not utilize the dialogue history beyond the previous system turn and contextual ambiguities are resolved by the downstream components. In this paper, we explore novel approaches for modeling dialogue context...

Spoken Language Understanding (SLU) is a key component of goal oriented dialogue systems that would parse user utterances into semantic frame representations. Traditionally SLU does not utilize the dialogue history beyond the previous system turn and contextual ambiguities are resolved by the downstream components. In this paper, we explore novel approaches for modeling dialogue context in a re...

Intelligent information systems are expected to interpret the users' information needs semantically, taking the dialogue context into account. Whereas many research prototypes attempt to address the semantic interpretation of queries, only a few try to reason about other aspects of the user's individual dialogue behavior. This paper introduces an approach to context-dependent interpretation of ...

The paper deals with a spoken dialogue system component – response generation module. We are developing the spoken dialogue system called CIC (city information centre) providing a subset of services of a real city information centre. The main focus of this article is an experiment with usage of UCG (Unification Categorial Grammar) for response generation within a dialogue system speaking Czech....

This thesis presents a design for an Intelligent Educational System to support the teaching of design evaluation in engineering. The design consists of a simple computer-based tool (or 'learning environment') for displaying and manipulating information used in the course of problem solving, with a separate dialogue component capable of discussing aspects of the problem and of the problem solvin...

A central problem for mixed-initiative dialogue management is coping with user utterances that fall outside of the expected sequence of the dialogue. Independent initiative by the user may require a complete revision of the future course of the dialogue, even when the system is engaged in activities of its own, such as querying a database, etc. This paper presents an event-driven, goal-based di...

In this paper we present an approach to complement speech dialogue applications written in VoiceXML with reasoning capabilities simplifying the integration of domain knowledge into the traditionally coded dialogue flow. One of the characteristic enhancements of our approach is the use of a dedicated reasoning component for processing the knowledge items acquired during the dialogue. The approac...
