Ensuring process execution reliability and success is crucial for business process management. A mechanism is required to link high-level requirements to transaction management and utilize runtime information to remedy occurred problems. However, workflow transaction models have a gap with high-level requirements, and their limited forward recovery mechanisms lead to lots of unnecessary aborts. This...
Time is a crucial factor in business process management. Business processes fail to accomplish when temporal inconsistency occurs between participants. Traditional temporal consistency verification methods only focus on available temporal information of web services, and the temporal constraint, which requires that the next service must be available after all previous services accomplish, is too strong...
Dynamic substitution of conversational services during the execution of service orchestrations is a challenging issue in Service-Oriented Architecture. For a conversational service and its candidate substitute service, there may exist mismatches at interface level as well as protocol level. To make the service substitution consistent, it is essential to implement adaptation to overcome both types...
Dynamic invocation has always been a hot issue in Web services in order to take full advantage of the flexibility of services computing. One key underlying enabling technology is a self-descriptive contact between the service consumer and provider. In the SOAP-based environment, WSDL has been proven a successful description language which is widely accepted. But for many years, we cannot get the equivalent...
With the growing number of web services ,the importance of matching and discovery web services is increasing. Using domain ontology to describe the semantic of web services and matching the web services on the semantic level is a hot research pot. In this paper, the problem of matching web services is transformed to the computation of semantic similarity between concepts in domain ontology. We propose...
