Collaboration in heterogeneous environments involves dealing with variety of information sources that generate information that users need to be aware of. Users must be empowered to tailor the quality of awareness information. Heterogeneity of sources and media adversely affects the quality of group awareness. We propose a solution in terms of integrating the sources at the information level and provide a model for the same. We discuss our progress in designing the model, its utility and benefits. We believe that such a unifying framework can increase the effectiveness of group awareness in supporting coordination and execution of collaborative work.

Every new technology promises to solve a lot of problems inside companies and to achieve unforeseen performance improvements. Nowadays, Service-Oriented Architectures begin to be promoted as new balsam where companies may realize their visions and put all their new strategies in practice. Initially focused on intra-organizational integration efforts, they begin to be used when supporting inter-organizational business processes engineering in networked organizations. Although these kinds of initiatives in most of cases are lead by major companies, the INPREX project (Spanish acronym for Interoperability in Extended Processes), here presented falls out this category. By contrast, this is an undergoing initiative leaded by a Small and Medium Enterprise (SME) and founded by a local government in Spain. In this work, we introduce the IDIERE Platform which has been designed for supporting three major requirements of networked enterprises: openness, flexibility and dynamism when deploying and executing distributed business processes

Over the coming years, many are anticipating grid computing infrastructure, utilities and services to become an integral part of future socioeconomical fabric. Though, the realisation of such a vision will be very much affected by a host of factors including; cost of access, reliability, dependability and security of grid services. In earnest, autonomic computing model of systems’ self-adaptation, self-management and self-protection has attracted much interest to improving grid computing technology dependability, security whilst reducing cost of operation. A prevailing design model of autonomic computing systems is one of a goal-oriented and model-based architecture, where rules elicited from domain expert knowledge, domain analysis or data mining are embedded in software management systems to provide autonomic systems functions including; self-tuning and/or self-healing. In this paper, however, we argue for the need for unsupervised machine learning utility and associated middleware to capture knowledge sources to improve deliberative reasoning of autonomic middleware and/or grid infrastructure operation. In particular, the paper presents a machine learning middleware service using the well-known Self-Organising Maps (SOM), which is illustrated through a casestudy scenario -intelligent connected home. The SOM service is used to classify types of users and their respective networked appliances usage model (patterns). The models are accessed by our experimental self-managing infrastructure to provide Just-in-Time deployment and activation of required services in line with learnt usage models and baseline architecture of specified services assemblies. The paper concludes with an evaluation and general concluding remarks.

A peer-to-peer complementary currency can be a powerful tool for promoting exchanges and building relationships for coordinated activities. i-WAT[11] is a proposed such currency usable on the Internet. It is based on the WAT System[15], a polycentric complementary currency using WAT tickets as its media of exchange: participants spontaneously issue and circulate the tickets as needed, whose values are backed up by chains of trust. i-WAT implements the tickets electronically by exchanging messages signed in OpenPGP[3]. This paper proposes an extension to the design of i-WAT to facilitate mutual help among people in need. In particular, we propose additional “reduction” tickets whose values are reduced over time. By deferring redemption of such tickets, the participants can contribute to reduce the debts of the issuers, as well as to accelerate spending. Applications of this feature include a relief to disaster-affected people. A reference implementation of i-WAT has been developed in the form of a plug-in for an XMPP[6][7] instant messaging client. We have been putting the currency system into practical use, to which the proposed feature will be added shortly.

Using the Internet as the medium for transporting sensitive business data poses risks to companies. Before conducting business electronically, a company should take preventive measures against data manipulations and possible data misuse. One initial step could be obtaining certainty about the true identity of a potential business partner responding to a request or tender. In this paper we report on the development of a concept for identity management to introduce trust for electronic negotiations. We describe the character of electronic negotiations and give an example for a possible use-case scenario of our concept. For this we choose the most complex type of negotiations in the business domain, which are interactive bilateral multiattributive negotiations. Based on a general application architecture for such negotiations developed in a research project, we show the necessity of security provisions and introduce a security concept for identity management. We argue that the development of authentication and authorization services for the identity management of business partners involved in a negotiation are not only crucial but also an enhancement for electronic marketplaces.

This paper considers the problem of integrating communication services that support group collaboration systems. Past experience has shown that heterogeneous communication services are extremely difficult to be integrated into collaboration environment and extended to meet continuous changing requirements. This paper aims at proposing a common, interoperable framework based on Web Services technology for integrating communication services in a collaboration environment. This framework allows the implementation of reusable communication services components that can be plugged into the collaboration system and be invoked on demand according to communication requirements of collaboration applications. Based on this framework, a prototype system called Rich Media Collaborative Workplace is developed. This system provides an integrated collaborative workplace with benefits of increasing productivity, saving cost and improving efficiency.

The correctness of a workflow specification is critical for the automation of business processes. For this reason, errors in the specification should be detected and corrected as early as possible at specification time. In this paper, we present a validation method for workflow specifications using model-checking techniques. A formalized workflow specification, its properties and the correctness requirements are translated into a timed state machine that can be analyzed with the Uppaal model checker. The main contribution of this paper is the use of timed model checking for verifying time-related properties of workflow specifications. Using only one tool (the model checker) for verifying these different kinds of properties gives an advantage over using different specialized algorithms for verifying different kinds of properties.

To systematize software development, many process models have been proposed over the years. These models focus on the sequence of steps used by developers to create reliable software. Though these processmodels have helped companies to gain certification and attain global standards, they don’t take into account interpersonal interactions and various other social aspects of software development organizations. In this paper we tackle one crucial part of the Coordination problem in Software Development, namely the problem of task assignment in a team. We propose a methodology to test a hypothesis based on how social networks can be used to improve coordination in Software Industry. In a pilot case study based on 4 teams of Masters Student working in a globally distributed environment (Holland and India), the social network structures along with the task distribution in each of the teams were analyzed. In each case we observed patterns, which could be used to test many hypotheses on team coordination and task allocation between them.
