In this paper, we explore the mechanisms by which conversants control the direction of a dialogue. We find further evidence that control in task-oriented dialogues is subordinate to discourse structure. The initiator of a discourse segment has control; the non-initiator can contribute

We will consider different approaches to dialogue management and assess their methods of dealing with different dialogue characteristics. In the second lecture

This thesis addresses the question of how intonation functions in conversation. It examines the intonation and discourse function of single-word utterances in spontaneous and read-aloud task-oriented dialogue (HCRC Map Task Corpus containing Scottish English; see Anderson et al., 1991). To avoid

A federated database system (FDBS) is a collection of cooperating database systems that are autonomous and possibly heterogeneous. In this paper, we define a reference architecture for distributed database management systems from system and schema viewpoints and show how various FDBS architectures

Aegis operations are 10–100 times faster than Ultrix,a mature monolithic UNIX operating system. ExOS implements processes, virtual memory, and inter-process communication abstractions entirely within a library. Measurements show that ExOS’s application-level virtual memory and IPC primitives are 5

in current computer technology. Ontologies provide a shared and common understanding of a domain that can be communicated between people and application systems. Therefore, they may play a major role in supporting information exchange processes in various areas. This book discusses the role ontologies

Currently, computational linguists and cognitive scientists working in the area of discourse and dialogue argue that their subjective judgments are reliable using several different statistics, none of which are easily interpretable or comparable to each other. Meanwhile, researchers in content

We examine BACKCHANNEL-INVITING CUES — distinct prosodic, acoustic and lexical events in the speaker’s speech that tend to precede a short response produced by the interlocutor to convey continued attention — in the Columbia Games Corpus, a large corpus of task-oriented dialogues. We show
