A large number of redundant Web services, offering similar functionality with different quality of service (QoS), can truly benefit an organization, if offered an adaptive discovery framework. State-of-the-art approaches cannot meet these requirements for enterprise setups that offer a managed infrastructure. This paper proposes a self-healing and self-managed open-source adaptive QoS-aware discovery...
Web Services has been more recently emerged as the technology of choice to realize Service-Oriented Computing (SOC), a significant computing paradigm. The accomplishment of customer's satisfaction and trust is thought-provoking for web service providers. Subsequently, the attainment of non-functional requirements (aka QoS measures) is still a critical research challenge in realizing the Web Service...
Cloud computing re-defined what, in ICT, can be delivered “as a service”. The new types of services increase the potential of some Service-Oriented Architecture concepts, e.g. dynamic discovery and composition of services. We envision a dynamic cloud-enabled service ecosystem in which different business actors cooperate in delivering scalable high-value services to the end user. The different providers...
Service-oriented architectures (SOA) allow a run time composition and exchange of independently developed services. Thus, the SOA paradigm is predestined for the easy development of distributed applications and software systems. Particularly in mobile settings is distribution a possibility to provide functionalities to devices with restricted resources. SOA and the common advances in the area of wireless...
Web service discovery has become a daunting task primarily due to its inability for allowing clients to articulate proper service search queries. Improving the quality of service search results could not be achieved unless we determine ways for correctly identifying Web service query goals. In this paper, we identify client goals when performing a Web service search. As part of this work, we introduce...
In this paper, we analyze the problems of existing Service Computing model and propose a closed-loop mechanism for service evaluating and discovering on the Internet which is not only compatible with the basic principles of Service Computing--loosely coupled, protocol independent and location transparent, but also can rank, classify and recommend services based on their real-time performance. This...
Web Services providing access to datasources with structured data have an important place in the SOA. In this paper we focus on modeling and discovery of generic data providing services (DPS), with the goal of making data providing services available for interactions with service requesters in contexts such as service composition and mediation. In our model RDF Views are used to represent the content...
