The Ypa project (De Roeck et al., 1998) is building a system to make the information in classiied directories more accessible. BT's Yellow Pages 1 provides an example of a classiied database with which this work would be useful. Accessibility in this context means allowing users (or call center operators) to query the Yellow Pages system using Natural(More)
Cue-Based Dialogue Act Classification Nick Webb Supervisors: Yorick Wilks & Mark Hepple In this thesis, we will address three research questions relating to the discovery and use of cue phrases for Dialogue Act classification. Cue phrases are single words, or combinations of words in phrases, that can serve as reliable indicators of some discourse function.(More)
The development of Embodied Conversational Agents (ECA) as Companions brings several challenges for both affective and conversational dialogue. These include challenges in generating appropriate affective responses, selecting the overall shape of the dialogue, providing prompt system response times and handling interruptions. We present an implementation of(More)
We present recent work in the area of Cross-Domain Dialogue Act tagging. Our experiments investigate the use of a simple dialogue act classifier based on purely intra-utterance features principally involving word n-gram cue phrases. We apply automatically extracted cues from one corpus to a new annotated data set, to determine the portability and generality(More)
Evaluation of complex, collaborative dialogue systems is a difficult task. Traditionally, developers have relied upon subjective feedback from the user, and parametrisation over observable metrics. However, both models place some reliance on the notion of a task; that is, the system is helping to user achieve some clearly defined goal, such as book a flight(More)
In this paper, we describe our experience with collecting and creating an annotated corpus of multi-party online conversations in a chat-room environment. This effort is part of a larger project to develop computational models of social phenomena such as agenda control, influence, and leadership in on-line interactions. Such models will help capturing the(More)
In this paper, we present an investigation into the use of cue phrases as a basis for dialogue act classification. We define what we mean by cue phrases, and describe how we extract them from a manually labelled corpus of dialogue. We describe one method of evaluating the usefulness of such cue phrases, by applying them directly as a classifier to unseen(More)
