In this paper we give graph-semantics to a fundamental part of the semantics of the service modeling language SRML: business configurations. To achieve this goal we use symbolic graph transformation systems. We formalize the semantics using this graph transformation system and illustrating it with a simple running example of a trip booking agent.
Workflow patterns contain basic features of business process, and describe activities and their execution ordering through different constructors, which permit flow of execution control. Pi-calculus, as a kind of process algebra, can be applied in business process modeling. In this paper, we introduced a formal semantics for workflow patterns, which is based on the Pi-calculus, to investigate some...
Statistical graphs are ubiquitous mechanisms for data visualization such that most, if not all, enterprises communicate information through them. However, many graphs are stored as unstructured images or proprietary binary objects, making them difficult to work with beyond the reports in which they are embedded. While graphs can be mapped to more common XML representations, these lack expressive semantics...
