Control and data dependencies represent prominent information for modeling, managing, testing and optimizing service based business processes (SBPs). BPMN 2.0, as a twofold-purpose language, can be used to both mode land execute these SBPs. However, there is neither tailored support nor implemented tool for dependency ananlysis of such processes.

Cloud monitoring and analysis are challenging tasks that have recently been addressed by Complex Event Processing (CEP) techniques. CEP systems can process many incoming event streams and execute continuously running queries to analyze the behavior of a Cloud. Based on a Cloud performance monitoring and analysis use case, this paper experimentally evaluates different CEP architectures in terms of...
The lack of semantics in WS-SecurityPolicy (WS-SP) hampers the effectiveness of matching security policies. To resolve this problem, we present a semantic approach for specifying and matching web service security policies. The approach consists in the transformation of WS-SP into an OWL-DL ontology and the definition of a set of rules which automatically generate semantic relations that can exist...
