Goal-oriented Dialog as a Collaborative Subordinated Activity involving Collective Acceptance

International audienceModeling dialog as a collaborative activity consists notably in specifying the content of the Conversational Common Ground and the kind of social mental state involved. In previous work (Saget, 2006), we claim that Collective Acceptance is the proper social attitude for modeling Conversational Common Ground in the particular case of goal-oriented dialog. In this paper, a formalization of Collective Acceptance is shown, besides elements in order to integrate this attitude in a rational model of dialog are provided; and finally, a model of referential acts as being part of a collaborative activity is presented. The particular case of reference has been chosen in order to exemplify our claims

Enzymatic variation in African clariid catfishes

Enzymatic polymorphism was examined at 13 protein loci in four African clariid catfish species : #Claria anguillaris (Linnaeus, 1758), #C. gariepinus (Burchell, 1822) and #Heterobranchus longifilis Valencienne, 1840. The latter appears to be closer to #C. anguillaris and #C. gariepinus than #C. ebriensis. These results correspond with recently published karyological and morphometrical data. Reproductive compatibility, under laboratory conditions at least, is demonstrated between #C. gariepinus and #H. longifilis. The hybrids were shown to be completely intermediate between the parental strains. (Résumé d'auteur

Pulling Back the Curtain on the Wizards of Oz

The Wizard of Oz method is an increasingly common practice in HCI and CSCW studies as part of iterative design processes for interactive systems. Instead of designing a fully-fledged system, the ‘technical work’ of key system components is completed by human operators yet presented to study participants as if computed by a machine. However, little is known about how Wizard of Oz studies are interactionally and collaboratively achieved in situ by researchers and participants. By adopting an ethnomethodological perspective, we analyse our use of the method in studies with a voice-controlled vacuum robot and two researchers present. We present data that reveals how such studies are organised and presented to participants and unpack the coordinated orchestration work that unfolds ‘behind the scenes’ to complete the study. We examine how the researchers attend to participant requests and technical breakdowns, and discuss the performative, collaborative, and methodological nature of their work. We conclude by offering insights from our application of the approach to others in the HCI and CSCW communities for using the method

D'une méthodologie de modélisation des connaissances du domaine à sa formalisation au sein d'un agent rationnel dialoguant

Les systèmes de dialogue développés dans les laboratoires de France Télécom R&D sont conçus comme des agents intelligents dialoguants.Dans cette approche, l'aptitude d'un système à dialoguer résulte de principes primitifs de raisonnement et de comportements coopératifs indépendants des connaissances relatives à un domaine sémantique particulier. Dans ce contexte, un changement d'application ou l'ajout de nouveaux services à un système de dialogue nécessite une définition sémantique de cette application ou de ce service. Nous nous intéressons à la construction semi-automatique de modèles se mantiques d'un domaine de connaissance à partir d'une description informelle de ce domaine en langage naturel.Les travaux de thèses que nous présentons ici ont un double objectif : (1) proposer une méthodologie de construction interactive d'un modèle sémantique ; (2) exprimer ces mécanismes dans un formalisme logique, comme des notions épistémiques utilisables de manière banalisée par un agent rationnel dialoguant.Les résultats obtenus sont illustrés par la mise en oeuvre d'un démonstrateur qui a été appliqué à plusieurs domaines sémantiques.RENNES1-BU Sciences Philo (352382102) / SudocSudocFranceF
