This paper is based on the research work done under the EU-FP6 research framework by the Digital Business Ecosystems project task WP32-B11. This research work has been part of an ongoing research attempt, aiming to develop a knowledge base of regulatory issues that arise from small medium enterprises (SMEs) membership of a Digital Business Ecosystem (DBE), primarily associated with development of FS/OS Software for commercial use. The view taken was to identify trust as the main component for SME participation in the DBE, and to analyze some main areas for trust regulation: privacy, e-signatures and security, jurisdiction and consumer protection. The paper concludes with remarks regarding the potential implications of developing a knowledge base of regulatory issue in the use of FS/OS software in the European SME sector for current and future SME engagement, whereas the knowledge base of regulatory issues is still being empirically tested and populated.

A key challenge of gene expression time series research is the development of efficient and reliable probabilistic models. In response, we propose an unsupervised conditional random fields (CRFs) model for gene expression time series clustering. Conditional random fields have demonstrated superior performance over generative models such as hidden Markov models (HMMs) in terms of computational efficiency on many sequence-data-based tasks. Yet their potential has not been previously explored in this field. In the proposed model, time series data are allowed to interact with each other via a voting pool scheme while clusters are progressively formed. Experiments based on both biological data and simulated data verify the suitability of our model to gene expression data analysis via the comparison with a recent work.

The increasing proliferation of independent application service providers is making traditional IT infrastructure insufficient when dealing with new issues that appear in a dynamic outsourcing business model. Quality of service (QoS) gradually becomes an essential benchmark to differentiate diverse service providers during service selection process. In this paper, we argue service selection can be deemed as a decision making process -to decide which services providers should be selected within the specified service provision context during a definitive timeslot. Thus, existing decision support approaches can be leveraged if applicable. Hence, we propose a service selection solution which utilizes the decision support systems module (DSS Module) to select the most appropriate service. In DSS module we introduce AHP model to carry out the service QoS measurement based on the Context-specific Quality Aspects. The contributions of this paper are two folds. Firstly, we provide a novel and feasible solution for QoS-based service selection and secondly, we apply DSS module into web services, thus opening a new, fertile ground for DSS research in service ecosystem literature.

In the advent of globalization and increasing tourism local companies and business get more and more attention from people in different parts of the world. In this paper the authors outline an approach which leads to a description of organizations and business, i.e. non-profit and profit organizations, with an emphasis on local or regional basis. For this, publicly available upper ontologies and business area and e-tourism ontologies are studied and used as appropriate, added by an ontology describing the concepts of locality, forming a Local Organizations and Business Ontology system (LOBO). As an example the authors set up an ontology for organizations and enterprises in Phitsanulok Province (Thailand). The system aims at establishing web based dynamic yellow pages as well as company and organizational histories with the help of the semantic web. Therefore the authors do not only use a spatial (regional, local) but also a temporal ontology. The ontology is implemented with Protege (OWL).

The rapid growth of computing, the Internet and telecommunications systems have resulted in a broad range of ways to communicate and access information. Telecommunication and data convergence promises a wide range of solutions that will increase productivity, reduce costs, and provide new opportunities and revenues for enterprises. Unfortunately, the access of converged telecommunication and data services has been isolated to specialised inflexible environments. Due to the versatile nature of multimedia convergence, an adaptable approach is required. True voice and data convergence must be accessible anywhere and anyhow. This paper presents a reconfigurable software architecture driven solution that dynamically composes, integrates and tailors voice plugins. The solution offers enhanced service effectiveness, flexibility and convenience for professionals on the move.

Awareness of social ratings such as reputation, credibility and trustworthiness plays a key role in digital ecosystems where autonomous agents collaborate in order to publish their services or search for services. The integration of these social ratings along with attribute matching presents a novel approach and strengthens stability and confidence in autonomous distributed communities. This ensures that the selection of the optimal service is guaranteed while minimizing general security and business related risks. In this paper we discuss a framework for service registration which is hosted in a P2P environment. Service consumers can discover services which are grouped based on their contexts. Both, services and group alliances are defined through semantically enriched metadata and social ratings.

Service-oriented computing is becoming an increasingly popular paradigm for modelling and building distributed systems in heterogeneous, decentralised, and open environments. However, proposed service-oriented architectures are usually based on centralised components, such as service registries or service brokers, that introduce reliability, management, and performance issues. In this paper, we present a fully decentralised service-oriented architecture built on top of a self-organising peer-to-peer infrastructure. This architecture is especially designed to support digital ecosystems due to its low deployment and maintenance cost and inherently decentralised nature.

Business intelligence and customer satisfaction would be two key factors that would be used by the digital media commerce companies. For business intelligence purpose annotations for transaction tracking are required and the customers want that the digital media be authentic. In this paper, we present a novel watermarking scheme that supports authentication and transaction tracking functionalities. The watermarking scheme makes use of finite state machine principles. The proposed scheme is blind and asymmetric as it does not require the original image for watermark extraction and the watermark extraction key is different than its embedding key. The algorithm is implemented and tested for its visual quality, compression overhead, execution time overhead and payload capacity. It is found that the algorithm has high visual quality, high payload capacity, low compression overhead and low execution time overhead.

In this paper we present a model for coordinating distributed long running and multi-service transactions in digital business EcoSystems. The model supports various forms of service composition, which are translated into a tuples-based behavioural description that allows to reason about the required behaviour in terms of ordering, dependencies and alternative execution. The compensation mechanism warranties consistency, including omitted results, without breaking local autonomy. The proposed model is considered at the deployment level of SOA, rather than the realisation level, and is targeted to business transactions between collaborating SMEs as it respects the loose-coupling of the underlying services.

Service-oriented architecture (SOA) is gaining acceptance in many application domains as a way to structure system for flexibility and for better alignment with business goals. Peer-to-peer (P2P) systems are suited to digital ecosystems for small and medium enterprises (SMEs) because they allow each service client machine to act also as a service provider. There is no large enterprise that acts as a central hub in the network of business relationships. SMEs organize themselves in complex web of dynamic inter-relationships within the digital ecosystem. Most present P2P system had been designed with a fixed infrastructure in mind rather than a wireless or mobile infrastructure. However, mobile wireless smart-phones are increasingly being used as business tools. This paper proposes an intelligent agent mediated peer-to-peer service-oriented architecture (SOA) that could be used to address the dynamic requirements of a mobile and fixed infrastructure and hence provide a seamless service environment of for SME digital business ecosystems.
