In a service ecosystem of complementary and competing web services, clients have many options but, at the same time, determining which one to trust can be a challenge. While there have been several proposals in literature about web services trust measurement, none has been actually adopted. Even the notion of trust itself is not clearly established in the context of the web-services' stack of standards. In this paper, we propose a service that collects different types of service-quality measurements from clients, as well as evidence in the form of relevant request/response headers, in order to produce aggregate trust metrics of service providers. Our experimental analysis using simulations shows that the proposed trust-aggregator service framework is feasible and effective in measuring trust metrics.
