TLDR
It is concluded that empirical studies of the unique qualities of man-machine interaction as distinct from general human discourse are required for the development of user-friendly interactive systems.Abstract:
Current approaches to the development of natural language dialogue systems are discussed, and it is claimed that they do not sufficiently consider the unique qualities of man-machine interaction as distinct from general human discourse. It is concluded that empirical studies of this unique communication situation are required for the development of user-friendly interactive systems. One way of achieving this is through the use of so-called Wizard of Oz studies. The focus of the work described in the paper is on the practical execution of the studies and the methodological conclusions drawn on the basis of the authors' experience. While the focus is on natural language interfaces, the methods used and the conclusions drawn from the results obtained are of relevance also to other kinds of intelligent interfaces.read more

Predicting Ratings of Real Dialogue Participants from Artificial Data and Ratings of Human Dialogue Observers
TL;DR: The results suggest that for three conversational aspects (intelligence, naturalness, overall quality) just training evaluation functions on simulated data could be sufficient.

Helping Users Customize Their Pedagogical Agents: Issues, Approaches and Examples
TL;DR: A pedagogical agent customizer (RuleEditor) that allows end users to modify the presentation and intervention attributes of the agent and includes the means for users to exercise a new form of control over their environment (“social empowerment”) that may extend as far as redefining social relations within a community of users.

Improving the reliability and validity of 'Wizard-of-Oz' methods
TL;DR: Despite the difficulty of synchronising evaluators’ individual expertise and experiences was admitted, the research findings suggested practical measurements to address the individual differences at acceptable levels through applying additional assistance and constraints to evaluator's system facilitation judgement and execution.

ChatWoz: Chatting through a Wizard of Oz
Pedro Fialho,Luísa Coheur +1 more
TL;DR: ChatWoz is an application that can be used as a Wizard of Oz, to collect real data for dialogue systems, but also to allow children to interact with their caregivers through it, as it is based on a virtual agent.

The development of communication skills: modifications in the speech of young children as a function of listener
Marilyn Shatz,Rochel Gelman +1 more
TL;DR: This paper found that the 4-year-old adjusted his speech with regard to the changing capacities of different-aged listeners, and the younger the 2-year old, the greater was the observed speech adjustment.

Cross-linguistic differences in parsing: Restrictions on the use of the Late Closure strategy in Spanish ☆
Fernando Cuetos,Don C. Mitchell +1 more
TL;DR: The results throw doubt on the suggestion that the Late Closure strategy is favoured (in English) mainly because it is efficient in information processing terms and suggest that different languages make use of parsing strategies in an essentially arbitrary way.

TL;DR: The “Wizard of Oz” technique for simulating future interactive technology and a partial taxonomy of such simulations is reviewed and a general Wizard of Oz methodology is suggested.
