The ability of service providers to adequately describe and publish their Web services is a critical factor to the success in their discovery by interested parties. To date, most of the efforts made towards this direction have mainly focused on the use of ontologies. However, the resulted approaches impose centralized control of the ontology vocabularies and/or schemas, suffer from considerable interoperability issues and require complex, heavyweight technologies. In this paper we present our ongoing work on a peer-to-peer platform supporting publication and discovery of Web services in a socially intelligent manner. The novelty of our approach is that it combines the P2P architecture with the principles of the social Web to enable autonomous, decentralized semantic annotation and maintenance of Web service descriptions, through the collective intelligence emerging by the social networking interactions between service providers and requesters.

The aim of this paper is to describe an intelligent system designed for assisting the personalized therapy of dyslalia for the Romanian prescholars children. This system is developed in the frame of TERAPERS project that can be included in a very important research area: informational technologies in response to society challenges - for health: early diagnosis, personalized therapy. Taking into consideration the fact that Romanian language is a phonetic one that has its own special linguistic particularities, there is a real need for the development and use of audio-video systems, which can be used in the therapy of different speech problems. The system has a high degree of originality because his objective is to treat the pronunciation disorders in Romanian language. Also the complexity of the project results from the high number of different research areas involved: artificial intelligence, virtual reality, digital signal processing, digital electronic and psychology.

In this paper we present an improved method for image partition. Image partition plays an important role in video segmentation techniques; it uses different region growth algorithms for separating an image into regions and objects. This enhances the characterization on an image using video descriptors and can be used in image retrieval or image comparison applications. The proposed segmentation method uses the Minkowsky metric for region detection. In addition, it uses different threshold values in order to achieve perceptually significant areas. The simulation results indicate good performances of the proposed method for colour image segmentation.

In this paper we are concerned with providing support for business activities in moving from value chains to value networks. We describe a fully distributed P2P architecture which reflects the dynamics of business processes that are not governed by a single organisation. The temporary virtual networks of long-term business transactions are used as the building block of the overall scale-free business network. The design is based on dynamically formed permanent clusters resulting in a topology that is highly resilient to failures (and attacks) and is capable of reconfiguring itself to adapt to changes in business models and respond to global failures of conceptual hubs. This fosters an environment where business communities can evolve to meet emerging business opportunities and achieve sustainable growth within a digital ecosystem.

This paper explores the role of product life-cycle management (PLM) systems in industry by evaluating their impact on business process improvement. In addition, future trends of these systems are also analyzed. A literature review and three case studies are used to answer specific research hypothesis, reflecting the suitability of qualitative research methods in this field. The case studies employed detailed questionnaires to support the literature review. Research findings indicate a strong correlation between PLM systems implementation and business process improvement. This is identified as a clear benefit for their deployment in engineering/manufacturing companies.

Users may use a mobile service in various contexts. It is critical to study how users' perceptions and intentions are affected by context. We discuss the definition and structure of context, then propose a contextual acceptance model of mobile commerce based on TAM. We apply this model to the case of a GPS-based taxi-dispatching system. Preliminary data analysis illustrates that context has significant impact on uses' behavior.

This paper proposes an approach to solving node weightings in a tree structure. The tree represents expertise used to quantify risks associated with mental-health problems and it is incorporated within a Web-based decision support system called GRiST. The aim of the algorithm is to find the set of relative node weightings in the tree that helps GRiST simulate the clinical risk judgements given by mental-health experts. The results show that a very large number of nodes (several thousand for GRiST) can have their weights calculated from the clinical judgements associated with a few hundred cases (200 for GRiST). This greatly reduces the experts' elicitation tasks by ensuring they do not need to provide their own estimation of node weights throughout the tree. The approach has the potential for reducing elicitation load in similar knowledge-engineering domains where relative weightings of node siblings are part of the parameter space.

A three-tier data distribution framework is proposed for grid-enabled data analysis applications. This framework is based on existing resource reservation services: the analytical tasks which this framework serves, and their input data, are assigned by an existing performance-aware scheduling system to computational hosts termed 'calculators'. A so-called 'guider' organizes the data delivery from the source server to the 'coordinators', and every coordinator schedules the data propagation from itself to all its calculators. This scheme, which we call DIAO, is peer-to-peer (P2P), in that after downloading a data item, a host may behave as its server. Theoretical modeling reveals that the duration of data distribution depends on the effective utilization of the bottleneck resource in the overlay, and we develop three heuristics to minimize this duration, subject to the available resources. The ability of DIAO to exploit limited resources is demonstrated through simulation.
