A promising approach to managing business operations is based on <i>business artifacts</i>, a.k.a. <i>business entities</i> (<i>with lifecycles</i>). These are key conceptual entities that are central to guiding the operations of a business, and whose content changes as they move through those operations. An artifact type includes both an <i>information(More)
Business process management, workflow, and case management are critical technologies for managing collections of services, including human activities, to support business operations. One way to manage business operations is based on business entities with lifecycles (BEL’s) (a.k.a. business artifacts), i.e., key conceptual entities that are central to(More)
In this paper we present an approach for specification of exception handling and recovery of semantic web services based on OWLS. We use standard fault handlers and compensation known for example from WS-BPEL to provide support for long running transactions. In addition to that, we introduce constraint violation handlers (CV-handlers) which allow a designer(More)
Web Services providing access to datasources with structured data have an important place in the SOA. In this paper we focus on modeling and discovery of generic data providing services (DPS), with the goal of making data providing services available for interactions with service requesters in contexts such as service composition and mediation. In our model(More)
Case Management, with its emphasis on the case folder as the anchor for managing business processes, is emerging as a way to provide rich flexibility for knowledge workers while retaining key advantages of BPM systems. This has introduced new challenges in connection with modeling case processes. This short survey traces the history of key modeling ideas(More)
Execution monitoring of complex web service process models is critical for effective management and control of web services based systems. During the composite process model execution or as part of the after-execution analysis complex event patterns (called composite events) consisting of various primitive events need to be detected. In this paper we(More)
Web service-based applications are widely used, which has inevitably led to the need for proper mechanisms for the web service paradigm that can provide sustainable and reliable execution flows. In this paper we revise recovery techniques in OWL-S and show how semantic annotations may ensure seamless web service provision in a sophisticated way, such as,(More)
Business artifacts provide an approach to Business Process Management that combines data and process in a holistic way. Previous research introduced artifact-centric Interoperation Hubs (I-Hubs) as a data-centric alternative to conventional service orchestration for enabling the cooperative interaction of multiple organizations with shared business(More)
In this paper we address the problem of modeling collaborative decision and knowledge intensive business processes (sometimes referred to as Decision Intensive Processes, or DIP processes). DIP processes assist users in performing decision intensive tasks, and provide users with a guidance relevant to process execution context. DIP processes are by nature(More)
