An equally important function of the system is to support communication within an organisation by structuring and coordinating the actions performed by the organisations agents. These two roles of a business system may be represented in terms of business and process models, i.e. the separation of the declarative economic aspects from the procedural control flow aspects of the system. Although this separation of concerns has many advantages, the differences in representation techniques and focus of the two model types constitutes a problem in itself. The main contribution of this paper is a unified framework to facilitate the analysis and integration of business models and process models in e-Commerce in a systematic way. The approach suggested bridges the gap between the declarative and social/economic aspects of a business model and the procedural and communicative aspects of a process model. We illustrate how our approach can be used to facilitate integration, process specification, process pattern interpretation and choreography.

One approach is to build libraries of reusable analysis patterns, ie abstract models describing the generic features of a type of situation that may occur in many different domains. In order to systematise libraries of such patterns, we propose a novel analysis pattern based on a deontic perspective. The basic components of this pattern are object types describing obligations, the parties involved in ...

The author shows how problems in schema integration can be analyzed using concepts from logic programming and deductive databases. It is shown how equivalent constructs of conceptual schemas can be represented by so called integration assertions.

Three issues in process management and modeling are identified: business orientation, traceability, and flexibility. It is shown how these issues can be addressed by basing process models on business models, where a business model focuses on the transfer of value between agents.

One technique for supporting validation is explanation generation, which combines paraphrasing of a specification with question–answer facilities that interactively support a user in exploring a model. In this paper, we propose an architecture and design principles for constructing explanation generation systems for conceptual models.

Software support for well structured business processes is today provided through workflow technology and process management tools. Tailored to support well structured processes, these tools do not provide adequate support for loosely structured work activities such as knowledge intensive processes. This type of work is heavily reliant on professional knowledge, deals with large amounts of data and tasks that can be redone several times.

The Semantic Web vision aims to integrate and convert the vast amount of information available on the Internet into a machine-understandable network. The objective is to promote knowledge sharing and reusability. Ontologies form a global pool of reusable, shared knowledge resources. Ontology languages, like RDFS, DAML or the W3C recommended OWL, make the knowledge base machine or platform independent. However, ontology use outside the realm of ontology experts is still limited.

An equally important function of the system is to support communication within an organisation by structuring and coordinating the actions performed by the organisation's agents. In many systems development methods, these different roles that an information system assumes are not explicitly separated. Representation techniques appropriate for one role are uncritically applied to another.

Addressed in this paper is the domain of interoperability and interoperable information systems. Enterprise analysis and modelling is an essential tool for achieving interoperability. However, the big number and diversity of enterprise modelling tools and techniques available today challenges the usefulness of enterprise modelling. Addressing this problem, a Unified Enterprise Modelling Language is under development.

Designed properly, executable processes can be used to closely support business processes by the integration of existing software services. In order to support business processes the design of the executable process must closely follow the business events and activities, as perceived by business actors. However, the design must also consider technical issues such as limitations in existing technology and systems.

Contemporary social software and business process support systems utilize different architectural principals. While social software employs the idea of shared spaces for communication/collaboration, most of the contemporary business process support systems employ a workflow engine to coordinate the work of people engaged in the given business process. There are two alternatives when developing a system that provides business process support enhanced with properties of social software.

For example, healthcare shall be equal, be of high quality, and at the same time be efficient. Mainly due to efficiency reasons, the healthcare sector is divided into different healthcare providers, such as home care, primary care, hospital clinics and private specialists. This results in an increased complexity, as different healthcare providers need to collaborate in order to fulfill their missions.

The Language Action approach, therefore, seems to be a most promising framework for designing e-commerce systems. However, the penetration of the Language Action approach in industrial practice is still limited. We discuss some reasons for this state of affairs by identifying a number of problems that hinder an effective application of the Language Action approach.

The Language Action approach that has a significant impact within CSCW, therefore, seems to be a most promising framework for designing e-Business systems. However, the penetration of the Language Action approach in industrial practice is still limited.

When modelling communication among agents, deontic concepts, such as obligations, permissions, and prohibitions are essential. The dynamics of obligations, ie how obligations are created and destroyed, can effectively be described by means of notions from speech act theory. In this paper, we present a language that includes deontic and illocutionary constructs for the modelling of communication between agents.

While a business model is concerned with value exchanges between actors, a process model describes the procedural realization of business requirements. There is a need for methodological guidelines and tool support to move from a business model to a process model, which enables design decisions to be based on requirements captured in the business model.

In this Chapter, we introduce the basic concepts of application integration, discuss a number of the most important issues in the area and outline promising research directions: process libraries, methodologies for process integration, adaptive and flexible process enactment, and moving business logic from systems to processes.

These problems can only be effectively addressed if the schemas are expressed in a semantically rich modelling formulation. We introduce such a modelling formalism that utilises linguistic instruments, in particular case grammar and speech act theory.
