Over the past years services computing has become an emerging science that is highly regarded as a necessary technology not only by research but by industry as well. In the same context, the advent of cloud computing gave to services and web applications a whole new perspective and potential. Regardless of the rapid evolution in the fields of services and(More)
While the Cloud computing paradigm is maturing and gaining wide acceptance, topics like Quality of Service assurance and resource monitoring will remain active fields of investigation and research. In this paper, we identify characteristics of the monitoring infrastructure in Cloud environments and we present a new architectural approach. The proposed(More)
Recent advances in the Semantic Web community have yielded a variety of reasoning methods used to process and exploit semantically annotated data. However, most of those methods have only been approved for small, closed, trustworthy, consistent, and static domains. Still, there is a deep mismatch between the requirements for reasoning on a Web scale and the(More)
Current service platform offers that provide Infrastructure as a Service (IaaS) do not adequately meet the requirements expressed by interactive real-time services. Online application response times can not yet be enforced in virtual infrastructures without service level objectives (SLOs) that meet virtual machine interconnection constraints. This paper(More)
The usage of parallelization and distribution techniques in the field of ontology matching is of high interest for the semantic web community. This work presents an approach for managing the process of extending complex information structures as used in Urban Computing system by means of ontology matching considering parallelization and distribution(More)
The aim of the Large Knowledge Collider (LarKC) project is to develop a platform for massive distributed incomplete reasoning for the Semantic Web. The LarKC Plugins – services that can be used in the LarKC platform play a key role in the context of LarKC. They are the core elements that are composed in a concrete LarKC pipeline – a(More)
Cloud Computing is considered nowadays as the future of ICT systems leveraging new methodologies for developing, providing and consuming services. Even though many people believe that “Cloud” is just another buzzword for utility computing, this new computing paradigm is not only changing the design of modern computing platforms in technical level, but it(More)
Among the advances that the world of distributed computing has had, one must take into account the emergence of new paradigms such as Cloud Computing. The Cloud Computing Model integrates and offers to users several computational resources as a service, on demand. The Cloud model is supported by technologies such as Grid Computing, virtualization and Web(More)
Recent advances in the Semantic Web community have enabled processing and exploitation of semantically annotated data by a variety of modern reasoning methods. However, there is still a deep mismatch between the requirements for reasoning on a Web scale and the existing efficient reasoning algorithms over restricted subsets. Fulfilment of those requirements(More)
current service platforms, e.g. Cloud solutions, do not adequately address the requirements exposed from certain kind of services like real-time services. Infrastructure as a Service Platform (IaaS) supporting these service requirements, such as quality of service of the resources provided, heavily depend on measurements in order to be able to verify that(More)
