With the growing number of botnet attacks, the botnet detection is becoming increasingly important for the network security. To enhance the existing botnet detection systems which are short of efficient information collection functions, this paper presents a collaborative information collection model with a new 5-tuple structural mode. In the model, we introduce the static and dynamic roles to meet...
A system that would harness the brainpower of vast numbers of humans and orchestrate their efforts could be used to solve hard problems that are beyond the reach of computational methods. This paper describes such a system. This system will use a recursive problem solving life cycle model based on a continuously evolving distributed supply chain infrastructure. The problems to be addressed using this...
Multidisciplinary Design Optimization (MDO) is increasingly adopted in engineering design currently, especially for complex engineering systems, however, the computation complexity and organization complexity are the two main obstacles in applying MDO. In order to degrade the computation complexity and organization complexity of MDO problem, in this paper, the BLISS method is adopted to decompose...
Many of today's large-scale scientific projects attempt to collect data from a diverse set of sources. The traditional campaign-style approach to ??synthesis?? efforts gathers data through a single concentrated effort, and the data contributors know in advance exactly who will use their data and why. At even moderate scales, the cost and time required to find, gather, collate, normalize, and customize...
Within the current economic context, enterprises are facing new interoperability issues due to increasing need of e Business Collaboration within the emerging digital ecosystems in which they belong. They also need to be able to keep in pace with their heterogeneous internal legacy systems, and can't change their infrastructure or applications for fast and short collaboration implying information...
Based on an extensive examining of different industrial and research resources we have recognized that SOA is one of the most progressive IT concepts in the enterprise management. Besides, the rise of social networking in the enterprise, the adoption of Enterprise 2.0, and the use of mobile applications in business are influencing the enterprise SOA development. Thus, in this paper, we focus onto...
The development of collaborative applications should take into account static and dynamic issues, as well as different technological aspects that allow adapting them to either several working groups' needs or new collaborative scenarios, since these applications have to be continuously running its correct functionality. For this reason, this paper presents a service-based layered architectural model...
The absence of a disciplined approach for capturing and managing architectural knowledge causes the loss of substantial knowledge generated during the software architecture process. This paper describes the use of a Spatial Hypertext Wiki (ShyWiki) as a tool for Architectural Knowledge Management (AKM) support. Specifically, we demonstrate that ShyWiki can be used for implementing lightweight knowledge...
With the fast popularization of the WWW, knowledge management (KM) plays more and more important roles in most of fields. But the centralized KM can not be adaptive to the Internet environment, because there may be more than one knowledge base including personal knowledge, organizational knowledge and domain knowledge in the distributed environment. Moreover it also involved in synergy knowledge in...
With rapid development of the Internet, the original knowledge management systems which are centralized control can not be adaptive to the distributed environment, because there maybe more than one knowledge bases including personal knowledge base in the collaborative environment and involve knowledge in each phase of implement process. Currently, to solve the issue of knowledge management in distributed...
Software development is tightly dependent on the tools available for supporting its processes. Organizational and sociotechnical peculiarities such as indefinition of roles, geographically distributed development teams, new business models and diverse cultural interactions steer these tools. Software development supported by web-based services, built on top of Web 2.0 technologies, is emerging as...
This project aims at recording the knowledge derived from the strategic process of designing the organization. To do this, a framework is proposed in order to capture the changing organizational architecture and acquire strategic knowledge. A software prototype is designed to support the proposed framework. The recording of organizational architecture and organizational intelligence adds a new perspective...
Seamless interoperability across system boundaries and optimally tailored solutions for customers are dominating concerns in the vision of future office infrastructures. This means to change the way how office systems are developed from todaypsilas ad-hoc integration of independent systems towards a collaborative approach for adequate systems of systems. In this paper, we propose a development method...
This paper mainly discusses about the architecture of CSCW. Three mainstream architectures have been proposed. A CSCW application that built upon the hybrid architecture will be more flexible than others since two other architectures can be seen as the special cases of the hybrid architecture. However, how to select the servers among the workstations remains an open discussion. Most of the selection...
Over the last years, e-learning needs have been evolving accordingly with more and more demanding pedagogical and technological requirements. Online learning environments no longer depend on homogeneous groups, static content and resources, and single pedagogies, but high customization and flexibility are a must in this context. As a result, current educational organizationspsila needs involve extending...
E-business and e-government implementations are becoming more and more widespread with growing number users depending on availability, accuracy and security of such e-services. The users must be able to trust these services, otherwise they will be reluctant to embrace the new opportunities and will not be able to reap the potential benefits. In addition, the end users wish to use the e-services in...
In the current globalized world, characterized by strong Web based interactions, relationships between people and organizations are subject to fast changes. This situation justifies the need for an approach that can capture business changes and quickly implement them into computational systems. Considering that some business logic portions are quite volatile and susceptible to changes and other portions...
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
The next generation Internet will be highly diversified in both underlying networking technologies and supported networking applications. The diversified Internet architecture requires effective collaboration among heterogeneous network domains to support various application requirements. One of the challenges to achieve this objective lies in enabling network domain collaboration and network-application...
