The finite-state based dialogue management approaches are powerful for simple tasks with strict and reliable dialogue control, while the plan-based dialogue management approaches are feasible for tasks with several topics or one complex topic. However, neither one is good enough for the dialogue control throughout in a dialogue task providing flight information inquiry and ticket reservation se...

We present preliminary research on the relation between written manuals and instructional dialogue, and outline how a manual can be converted into a format which can be used as domain knowledge by a dialogue system, capable of generating both instructional dialogue and monologue. Starting from a short sample text from a manual, we use the TRINDI information state approach (Traum et al., 1999) t...

This article examines cinematic remembrances of the Atlantic slave trade through the lens of Paul Robeson-starring British film The Song of Freedom (1936). An exceptional visualization of the horrors of the Middle Passage in transatlantic interwar cinema, the production nevertheless recapitulates an abolitionist visual paradigm characterized by lacunae and distortion. Yet, it also serves as an ...

[1] Benthic foraminiferal dC and Cd/Ca studies suggest that deep Atlantic circulation during the Last Glacial Maximum was very different from today, with high-nutrient (low dC, high Cd) deep Southern Ocean Water (SOW) penetrating far into the North Atlantic. However, if some glacial dC values are biased by productivity artifacts and/or air-sea exchange processes, then the existing dC data may b...

Many researchers have been developing natural language dialogue systems as a human-friendly man-machine interface. The human factors in a man-machine dialogue, however, are not obvious enough to understand with regard to how people talk with a dialogue system. 141 dialogues which our dialogue system had in DiaLeague '97 were analyzed at the utterance and dialogue levels, where DiaLeague '97 was...

Training task-oriented dialogue systems requires significant amount of manual effort and integration of many independently built components; moreover, the pipeline is prone to errorpropagation. End-to-end training has been proposed to overcome these problems by training the whole system over the utterances of both dialogue parties. In this paper we present an end-to-end spoken dialogue system a...

Dialogue in commercial games is largely created by teams of writers and designers who hand-author every line of dialogue and hand-specify the dialogue structure using finite state machines or branching trees. For dialogue heavy games, such as role playing games with significant NPC interactions, or emerging genres such as interactive drama, such hand specification significantly limits the playe...

Dialogue act modeling in task-oriented dialogue poses significant challenges. It is particularly challenging for corpora consisting of two interleaved communication streams: a dialogue stream and a task stream. In such corpora, information can be conveyed implicitly by the task stream, yielding a dialogue stream with seemingly missing information. A promising approach leverages rich resources f...

This paper presents a principled approach to reducing the occurrence of communication failure in spoken language dialogue systems. A set of principles for cooperative human-machine dialogue has been developed based on the development of the dialogue component of a spoken language dialogue system and on human-human dialogue theory. The principles have been tested on the dialogue corpus from a co...

Dialogue model design for spoken language dialogue systems (SLDSs) is still based mainly on common sense, experience and intuition, and trial and error, rather than on established design principles. Co-operativity in dialogue is crucial to habitable human-machine spoken dialogue. The paper presents a set of principles of co-operative user-system dialogue which have been derived from a corpus of...
