For its reuse advantages, workflow patterns (e.g., control flow patterns, data patterns, resource patterns) are increasingly attracting the interest of both researchers and vendors. Frequently, business process or workflow models can be assembeled out of a set of recurrent process fragments (or recurrent business functions), each of them having generic(More)
For their reuse advantages, workflow patterns are increasingly attracting the interest of both researchers and vendors. However, actual workflow modeling tools do not provide functionalities that enable users to define , query, and reuse workflow patterns properly. In this paper we gather a set of requirements for process modeling tools that aim to support(More)
Recently, a variety of workflow patterns has been proposed focusing on specific aspects like control flow, data flow, and resource assignments. Though these patterns are relevant for implementing Business Process Model-ing (BPM) tools and for evaluating the expressiveness of BPM languages, they do not contribute to reduce redundant specifications of(More)
Virtual Organizations (VO) have emerged as a new type of inter-organizational relationship for dealing with emerging challenges. The information system support for a VO poses new challenges to system design. Recent works define three levels of abstraction, namely an intentional level, an organizational level, and an operational level. For such a staged(More)
Research on workflow activity patterns recently emerged in order to increase the reuse of recurring business functions (e.g., notification, approval, and decision). One important aspect is to identify pattern co-occurrences and to utilize respective information for creating modeling recommendations regarding the most suited activity patterns to be combined(More)
Workflow activity patterns represent a set of recurrent behaviours that can be found in a wide range of business processes. In this paper we address the problem of determining the presence of these patterns in process models. This is usually done manually by the analyst, who inspects the model and interprets its elements in terms of the semantics of those(More)
Modern organizations have demands of automation of their business processes, once they are highly complex and need to be efficiently executed. For this reason the number of systems based on information technologies able to provide a better documentation, standardization and coordination of the business process is increasing. In this context, workflow(More)
