The Web services technology allows for easy creation of complex applications consisting of smaller components - Web services. This article performs an in-depth analysis of a Web services’ reliability problem for both atomic and composite web services. Is there really a problem of low reliability for composite applications?
Service oriented architecture is gaining momentum. However, in order to be successful, the proper and up-to-date description of services is required. Such a description may be provided by service profiling mechanisms, such as one presented in this article. Service profile can be defined as an up-to-date description of a subset of non-functional properties… (More)

This framework contains the definition of the semantic-related components, the dependencies that exist between these components, and the implementations of components that could be used. The following… (More)
Security and trust aspects, perceived as difficult to quantify, have been neglected in various service interactions. However, factors related to security and trust are in fact crucial in the overall value of service quality. A security ontology that enables a quantification of risks related to the usage of Semantic Web services in enterprise information… (More)
