Service Orientation has been an extensively used approach to model the services Collaborative Networks' (CN) members are willing to provide to customers. The evolution of this paradigm has followed an improvement path since its early forms. Nevertheless bottlenecks still exist, namely in what concerns: 1) a gap between the business and the information and communication technology perspectives; 2) an adequate Quality of Service (QoS) assessment mechanism for the CN context. As a contribution to these issues, this paper proposes: 1) the creation of a collaborative Service Ecosystem, introducing pro-activeness elements towards an auto-initiative representation of CN member's services; 2) the introduction of a QoS mechanism needed to facilitate the assessment of services in a CN context.

In a Collaborative Network (CN) scenario it would be desirable that CN members could be able to start collaboration within their Virtual Organization Breeding Environments or Professional Virtual Communities in a short time-frame, whenever a new Business Opportunity appears.

As a contribution towards such dynamic scenario, this paper proposes the concepts of Assets Entity, Pro-Active Assets Entity and Integrated Market of Pro-Active Assets Entities. The first concept can be used to model attributes and all functional and intelligent content elements a CN member can provide (its Assets). The second is responsible for the representation and promotion of an Assets Entity. The later offers an adaptation of the market place concept where each Pro-Active Assets Entity registers itself, brokers post their needs and try to find the best providers, through a bidding and negotiation process.

Collaborative-Networks (CN) have experienced a fast evolution in the last two decades. The
collaboration among independent entities or professionals supported by Information and
Communication Technology (ICT) has attracted the research community to establish the
conceptual basis for this scientific discipline. Service Orientation has been one of the key selected
paradigms for that conceptual basis. Nevertheless, the service concept itself does not have a
common understanding in the Business and ICT worlds. In the former, client satisfaction,
resources management and business process models are some example concerns, whilst the later
deals with interoperability, remote function calling or communication protocols.
If for example an enterprise provides some service, it may hire specialists to wrap such
service into web-services, expecting to reach worldwide potential new clients. In fact, nowadays
Web Services and Service Oriented Architectures (SOA) are the technological elements most
commonly used. However, these are passive elements in the sense they do not perform any action
towards pursuing business interests, which constitute a limiting factor from a business
perspective. Another approach for the above mentioned enterprise is to follow the Multi-Agent
Systems (MAS) approach, as the pro-activity is a keyword in such contexts. Nevertheless, as
MAS approaches are not so commonly used and not so robust yet, the worldwide potential set of
new clients is reduced; which also constitutes an inhibitor factor from the business perspective.
This dissertation proposes a Pro-Active Services Ecosystem Framework, gathering
inspiration from both the SOA and MAS research areas, trying to bridge the business and ICT
worlds through the base concepts for the creation of a Services’ Ecosystem where business
services are represented in a pro-active manner towards pursuing business interests, like finding
collaboration opportunities or improving the chances each CN member has to see its services
selected among competitors, for example. This work also includes a prototype system applied /
validated in the area of a Professional Virtual Community of Senior Professionals.

The design and development of a transparent, easy to use and affordable ICT infrastructure is a key pre-requisite for the effective large-scale implementation of the collaborative network organizations such as virtual organizations, professional virtual communities, e-science communities, etc. This chapter introduces an overview of the main classes of infrastructures required by different types of virtual organizations and summarizes the main approaches followed by a number of research projects in the area.

Within a Collaborative Business Ecosystem context, as the network evolves, the competition between members increases and, as a consequence, members face the challenge to improve the chances their services have to be selected. On the other hand, the distance between Business Services and “Computational Services” is still a bottleneck for the automation of service provision. This paper extends the Pro-Active Service Entity Framework, proposing a mechanism to improve the service selection chances, based on the refinement of a Quality of Service concept for this context, and introduces a new class of actors for the framework – the intermediaries, needed to shorten the distance between Business and Computational perspectives.

A sociedade organizou-se para fazer frente a necessidades como o tratamento e acompanhamento de crianças ou jovens com Síndrome de Down, Surdez, Autismo, entre outras patologias. Como resultado, surgiram distintas organizações com o objetivo de lidar com estes casos, compostas por médicos, terapeutas, psicólogos, sociólogos e outros profissionais, mas excluindo profissionais dedicados ao desenvolvimento de novas tecnologias. Por outro lado, alunos finalistas de cursos tecnológicos desenvolvem normalmente um projeto tecnológico do início na disciplina final dos seus cursos - Projeto/Dissertação de fim de curso. Este artigo propõe um método para aplicar o esforço e entusiasmo de tais alunos às causas sociais mencionadas através do desenvolvimento de Jogos.

The practical implantation of the concept of dynamic virtual enterprise is still far from expectations due to a number of factors such as the lack of appropriate interoperable infrastructures and tools, lack of common ontology, and the socio-organizational difficulties. However, the creation of industry clusters supported by advanced information and communication tools can meanwhile provide a basis for the rapid creation of dynamic virtual enterprises in response to the market opportunities. A federated service management approach is introduced in this context and its application to the tourism industry is discussed. Finally, the support for the aggregation of simpler services into value-added services, implemented by distributed business processes within different organizations, is presented.

A proposal for a reference curriculum for teaching Collaborative Networks at university level is introduced. This curriculum is based on the experience of the authors in teaching and disseminating corresponding concepts in the context of several international projects as well as on the findings of a survey conducted worldwide. A set of teaching units and the corresponding content are introduced. Guidelines for the application of the curriculum are given. A set of experiments and projects are also suggested as a support for the accompanying hands-on lab work. Finally, one concrete experience of application of the proposed curriculum is described.

Electronic procurement of partners is an important functionality during the life cycle of a virtual enterprise. A prototype implementation, featuring selection based on both internal or Internet-based suppliers’ directories, is discussed. The generation of call for tenders and support for management of received bids is introduced and directions for contract negotiation and decision support system are discussed.

The introduction of new courses on virtual organizations at the engineering education level is an important element for the broad acceptance of this new paradigm. This article summarizes the experience with an initiative of teaching Virtual Enterprises / Virtual Organizations subjects to Electrical and Computer Engineering students. The course structure, both in its lecture and lab work components, is described. Finally, some lessons learned with two editions of this course are presented.

Partners search and selection is an important activity in the life cycle of a Virtual Enterprise. Among other factors, the commitment of the potential partners to fulfil quality requirements is a major decision criterion during the selection phase. An approach to search suppliers in suppliers’ directories available on Internet is presented and the major negotiation steps leading to an adequate selection of partners are introduced. The quality-related information management functionalities required in a virtual enterprise support platform are also discussed.

Nowadays there is a clear increase of products or tailored solutions with the goal of better adept to the needs of
clients. In another context there is a wide growth of computers’ presence in the class rooms, in order to assist
the teacher to captivate and motivate the students using educational games. However not all teachers have the
advanced computer knowledge that would allow them to personalize games, which would benefit children by
providing tailored solutions to their specific needs. Having this problem into consideration it was designed/idealized a system that relies on a framework of game creation that allows a user with less informatics skills to create a game based on a model. Although there are many games of this type it would be useful and innovative for a teacher to be able to create a game that is personalized to the students’ needs and according to the skills that they wish to develop. This system consists in an interface where the user has to follow some established steps, in order to achieve a file containing all the game features, which is later imported to
a framework. That system allows the creation of different games, as long as these games come under the same game mechanics.
