Abstract
This paper concerns the applicability of reputations systems for assessing
Quality of Experience (QoE) for web services in Future Internet. Reputation
systems provide mechanisms to manage subjective opinions in societies
and yield general scoring of a particular behavior. Thus, they are likely to become
an important ingredient of Future Internet. Parameters being under evaluation
by reputation system may vary greatly and, particularly, may be chosen to
assess the users’ satisfaction with (composite) web services. Currently, this satisfaction
is usually expressed with QoE, which represents subjective users’
opinions. The goal is to predict users’ satisfaction based on reputation values.
This may be beneficial for service providers in terms of checking the fulfillment
of SLAs, for retaining QoE on the satisfaction level for other users sharing the
same network or service resources, and for providing the users with indications
which resource to choose in order to maximize its experience.
