Résumé

Accurate estimation of quality of online services is both an important and difficult problem, since a service has many interdependent quality attributes influenced by several contextual factors. It is even more challenging as quality ratings come from sources with unknown reliability, each source may rate a service on different quality aspects. Although several solutions have been proposed, there is little work addressing all these issues thoroughly. In this paper, we show that domain knowledge on service structure and related constraints, such as causal dependencies among quality attributes and contextual factors, while widely available, can be exploited to effectively address the above issues in a theoretically-sound framework. Theoretical analysis shows that computational cost of the approach is acceptable, and accurate evaluation of service quality requires a reasonable number of user feedback, provided services have a small number of quality attributes and contextual factors.

Management de la qualité

vignette|La roue de Deming illustre le processus d'amélioration continue, l'un des principes fondamentaux du management de la qualité. Le management de la qualité, ou gestion de la qualité, est une discipline du management regroupant l'ensemble des concepts et méthodes visant à satisfaire les clients d'un organisme (en général les entreprises, associations, organismes publics) et à fournir des produits et services correspondant à leurs attentes.

Quality (business)

In business, engineering, and manufacturing, quality – or high quality – has a pragmatic interpretation as the non-inferiority or superiority of something (goods or services); it is also defined as being suitable for the intended purpose (fitness for purpose) while satisfying customer expectations. Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood differently by different people. Consumers may focus on the specification quality of a product/service, or how it compares to competitors in the marketplace.

Contrôle qualité

vignette|Contrôle qualité du nylon, 1954, Malmö. Photographie conservée au musée nordique. Le contrôle qualité est un aspect de la gestion de la qualité. Le contrôle est une opération destinée à déterminer, avec des moyens appropriés, si le produit (y compris, services, documents, code source) contrôlé est conforme ou non à ses spécifications ou exigences préétablies et incluant une décision d'acceptation, de rejet ou de retouche. L'ancienne norme ISO 8402 (maintenant annulée) en donnait la définition suivante : (ISO8402:1994, § 2.
