Distinguishing between two crus : as easy as picking the right side ? : Effect of expertise on conceptual and perceptual representations of Beaujolai…
2017
L’expertise a été étudiée en psychologie cognitive afin de comprendre les mécanismes psychologiques et les compétences intervenant dans différents domaines d’expertise. Dans le domaine du vin, les quelques études menées suggèrent que les experts organiseraient leurs connaissances autour de « prototypes » de couleur ou de cépage. L’objectif général de cette thèse visait à répondre aux questionnements théoriques concernant les représentations des vins d’experts et de novices, ainsi qu’aux questionnements de la filière concernant les perceptions des vins du Beaujolais. Pour cela, l’effet de l’expertise sur les représentations des vins a été évalué en comparant les performances de trois panels …

Expertise was studied in cognitive psychology in order to understand the psychological mechanisms and the abilities involved in various areas of expertise. In the wine field, the few studies conducted on expertise suggest that the knowledge representation of experts is organized around “prototypes” derived from wines of different colours or grape varieties. The general purpose of this thesis was to address 1) theoretical questions about knowledge representation of wines among experts and novices, and 2) wine industry questions about Beaujolais wine perceptions. To this end, the effect of expertise on knowledge representations of wines was evaluated by comparing the performance of three diff…
From quantitative spatial operators to qualitative spatial relationships : a new approach applied to the detection and the semantic qualification of …

This work presents the 3D Spatial Qualification tool (3DSQ) which was created tocompute spatial data stored in OWL-DL ontology. By using the adjustment principle ofan existing ontology, it is then possible to add 3D data to existing objects and computetheir spatial relationships from their 3D models. The 3DSQ Platform makes an attempt toensure the interaction between heterogeneous environments. Actually, such a semanticplatform connects an adjusted OWL ontology structure, a 3D quantification engine, avisualization engine and a set of geometry via knowledge processing technologymaterialized via SWRL, SQWRL rules and SPARQL queries within its extended Built-Ins. The created Spatial Built-Ins …
