The digital business ecosystem (DBE) paradigm envisages a business environment in which digitised content plays paramount role in the successful operation of small to medium enterprises (SMEs). Use of multimedia content -that includes text, audio, stills and moving images -has become the norm for most business and personal communications. The third generation (3G) mobile communications infrastructure aims to provide the ability to deliver this content over wireless networks. However, achieving the desired quality of service (QoS) remains a challenge. The fourth generation (4G) mobile systems are expected to tackle this problem over the coming years. Multimedia information and mobile communication systems need to become an integral part of the process adopted for the development of DBEs. The ability to transmit multimedia information effectively will play a significant role in the adoption of the DBE paradigm by the SMEs.

A business ecosystem is a term introduced by James Moore where in "The Death of Competition: Leadership and Strategy in the Age of Business Ecosystems" wrote on page 26 that a Business Ecosystem is based on dynamic interaction of organizations which evolves over time their capabilities and roles. To this extent this paper will tell that service oriented architecture (SOA) is not adequate to face such challenges which are unique in the context of a digital ecosystem (DES). The author will highlight such differences and describe the features of a new architectural style: called ecosystem oriented architecture (EOA). The paper will explore the fact that a DES oriented architecture is not a "sort of SO A", it's not just a "bigger SOA". A whole set of new problems are to be addressed namely responsive alignment with the business, decentralization, ownership of the knowledge base and self healing. EOA is a new mindset in decentralized architectures for DES.

Web service is an emerging paradigm for distributed computing. In order to verify web services rigorously, it is important to provide a formal semantics for flow-based web service languages such as BPEL. A suitable formal model should cover most features of BPEL. The existing formal models either abstract from data, cover a simple subset of BPEL, or omit the interactions between BPEL activities. This paper presents Web Service Automata, an extension of Mealy machines, to fulfil the formal model requirements of the web service domain. Secondly, the paper analyses the control handling and data handling of BPEL, so that these can be verified in a clear manner.

Efficient matchmaking is an important problem in unstructured and decentralized digital environments. We report the results of simulations of these environments and provide measurements of match performance focusing on unstructured and decentralized environments. In the study, different environment models including P2P (Hypergrid, Gnutella with/without ultrapeer); small-world (Watts-Strogatz); heavy-tailed and random versions of Autonomous System Waxman model showing power-law distribution property; random and 2D-Grid are considered. The flooding mechanism enabling process encounters for match purposes is uninformed breadth-first-search. Simulations show that the matchmaking performance of random environment outperforms the others for almost all different problems and time-to-live settings. On the other hand, the total cost of small world environment model is the highest for almost all setups.

Within the last few decades, information and communication technologies (ICT) have transformed the face of business, prompting the evolution of a more complex and dynamic digital economy. Such technologies disrupted the very fabric of business operations, affecting wholesale adaptation and subsequent reliance. Nonetheless, with new breeds of interactive social mediums like Web2.0 threatening to again alter the rules of engagement, management is steadily seeking a better understanding of how to cope with change and uncertainty. It is here where the science of complexity offers insight into the intricacy of modern organisational system reality, unearthing a context unto which a new appreciation of organisation design and the processes of its transformation may be inferred. Not serendipitously, the application of these systemic approaches to organisational system behaviour and development is delivering a perspective which is participative, diverse, interdependent and emergent; a compelling alternate view challenging mainstream organisational methodological selection and pursuant epistemological positions.

Trust measures the relationship between commitment and perceived execution of contracts in simple offer, accept, reject negotiation, and is the foundation for the confidence that an agent has in signing a contract. Negotiation is an information exchange process as well as a proposal exchange process. A rich decision model for intelligent agents involved in multi issue negotiations is described. The model, grounded on information theory, takes into account the aspects of trust and preference to devise mechanisms to manage dialogues.

A diagnosis of brain death is made according to precise criteria and in a well-defined process. Since the determination process of brain death usually takes long time and with a high risk, such as removing a breath machine in an apnea test, a practical, safety and rapid method is expected to be developed as the pre-test of the determination of brain death. In this paper, we propose a practical EEG examination method associated with a scale-free approach of blind signal separation for the pre-testing of the brain death determination. Through the analysis of the patient's EEG data by our proposed approach, a deep-coma patient or a brain death patient can be distinguished.

The evolution of collaborative environments towards digital ecosystems comes with increased risks to personal data and entity privacy. To address privacy protection concerns we propose a conceptual framework that integrates technical, legal and contextual components to provide comprehensive system wide privacy. Part of the framework is a privacy evaluator module (PEM). The PEM's function is to assimilate individual information system privacy protection strategies into a consistent ecosystem wide approach.

of keynote talk by Dr. Paolo Dini: In this talk I will attempt to give an overview of the emerging field of Digital Ecosystems research. I will outline some of the significant events and conceptual turning points of the past few years, the current activities, and the future challenges. In all cases my comments will be divided into two parts: the first part focuses on digital ecosystems as an Open Source technology inspired by biological ecosystems; the second part extends the meaning of the term to encompass the people and the companies that populate DEs, and the collaborative/ communicative processes by which new business and economic models are being forged. Keeping these two perspectives distinct and faithful to their respective philosophical traditions has enabled us to begin to understand how the process of formalisation of knowledge can couple constructively the behaviour of the very different kinds of actors inhabiting these two interacting epistemological spaces. Meanwhile, Digital Ecosystems are emerging in different parts of the world, in different socio-economic and cultural contexts, and can already provide a broad range of case studies for sustainable development. The talk will conclude with an overview of the interesting initiatives taking shape within and across the growing world-wide network of digital

Today, in the Information era businesses live in a dynamic environment where decisions need to be made quickly as otherwise they would not be able to survive. To investigate how businesses adjust to changing requirements in the Digital Eco-System we used the Cynefin Framework and its dimensions. Through a review of the literature, it was identified that there are two distinctive types of organisations: task-based and process-based. Although, in reality the majority of organisations these days fit somewhere in between. Furthermore, we found that organisations which are more process-based adapt to environmental changes more quickly than those that are task-based. Therefore, to be able to act quickly and make decisions in the Digital Eco-System task-based organisations are encouraged to eTransform and become process-based.
