We propose different behaviour and interaction related indicators of artificial actors (bots) and show how they can be separated from natural users in a virtual dating market. A finite mixture classification model is applied on the different behavioural and interactional information to classify users into bot vs. non-botcategories. Finally the validity of the classification model and the impact...

interactional requirements are expressed in terms of predicates on the state of the interactive system or properties of event traces (Blandford, Harrison and Barnard, 1993a). For example, one requirement on the interaction may be that the system must be “reset” to a state such that further interactions are possible whatever the outcome of the current one. The formal expression of this requireme...

This article presents a corpus featuring children playing games in interaction with the humanoid robot Nao: children have to express emotions in the course of a storytelling by the robot. This corpus was collected to design an affective interactive system driven by an interactional and emotional representation of the user. We evaluate here some mid-level markers used in our system: reaction tim...

Speaking as part of a conversation is different from reading out aloud. Speech synthesis systems, however, are typically developed using assumptions (at least implicitly) that are more true of the latter than the former situation. We address one particular aspect, which is the assumption that a fully formulated sentence is available for synthesis. We have built a system that does not make this ...

This work is based on the premise that the interactional construction of meaning is as important in online settings as it is face-to-face, especially in collaborative learning. Most studies of online learning use quantitative methods that assign meaning to contributions in isolation and aggregate over many sessions, obscuring the situated procedures by which participants accomplish learning thr...

Generally, human resources play an important role in manufacturing systems as they can affect the work environment. One of the most important factors impressing on worker performance is there being an interactional interest between workers in workshops. In this paper, we deal with this new concept in cellular manufacturing systems (CMS). Besides the existence of interactional interest, workers ...

This paper examines the phenomenon of interdisciplinary collaboration to critically appraise the widespread idea that working together requires the integration of knowledge. We build both on the concepts of common ground/grounding and interactional/contributory expertise to analyze in two case studies how common ground evolves in practice. We find that building common ground is a continuous pro...

Mobile phone use in cars is a highly debated issue. Legislation and policy discussions flourish in many countries and coincide with an increased effort in design of new in-car technologies. The studies which influence policy and design decisions use experimental approaches and are based on a cognitive perspective. In this paper, we discuss why this is a problematic approach. Further, we provide...

Aceptado: 05/12/2013 The objective of this study is to show how conversation analysis, a sociological discipline, approaches the study of social institutions. Social institutions are conceived as the crystallization of members’ communicative, interactional practices. Two institutional domains—psychiatric interviews and broadcast news interviews —and a specific interactional practice—‘formulatio...
