Spam messages are becoming a serious problem for most system administrators and computer users. Along with the increase in spam volume there is also a need for efficient detection methods which are able to cope with the analysis of thousands of emails per day. In this article we present a novel solution for spam detection which is based on a service oriented architecture, able to scan and classify a large number of emails. We prove that the service based architecture is scalable, capable of using a distributed system to split the computation along multiple nodes. This approach is not only very efficient and capable of handling large volumes of emails, but also very configurable, allowing the rapid change in scanning policy.

Scientific communities are actively developing services to exploit the capabilities of service-oriented distributed systems. This exploitation requires services to be specified and developed for a range of activities such as querying, management and scheduling of workflows, image handling, provenance capture and management, amongst other activities. Most of these services are designed and developed for a particular community of scientific users. A key issue here is that the constraints imposed by architectures, interfaces or platforms can restrict or even prohibit the free interchange of services between disparate scientific communities who have a shared need for a particular service. Using the notion of "Platform as a Service" (PaaS), we propose an architectural approach that addresses these limitations so that that users can make use of a wider range of services without being concerned about the development of cross-platform middleware, wrappers or any need for bespoke applications in order to cross the boundaries between differing communities. The proposed architecture shields heterogeneous Grid and Cloud infrastructural detail with a brokering environment, thus enabling users to concentrate on the specification of higher level services that are more relevant to the intended application.

Today smart phones integrate many sensors and provide large computing capacities. They enable the shift towards massive quantities of real-time information becoming access push rather than demand pull on a global case. In this we describe CAPIM, a platform to support such a paradigm. It integrates services to monitor and a context for adapt with the user's context using sensors and capabilities of smart phones, together with online social data. It integrates context-aware services that are dynamically configurable and use the user's location, identity, preferences, profile, and relations with individuals, as well as capabilities of the mobile devices to manifest themselves in many different ways and re-invent themselves over and over again. Such services aggregate and semantically organize the context data. They react based on dynamically defined context-oriented workflows, and the platform includes an execution engine that supports context-aware actions for orientation, information, and recommendation. We describe the design of our system, the challenges that need to be solved, and the evaluation methodology we are planning to adopt.

How does one capture value from delivering digital music files which users expect to download for free? This is the fundamental challenge the music industry currently faces. Therefore, new service-based business models are required that incorporate the increased consumption of music on mobile devices, pervasive social networks, peer-to-peer technology, and the internet as the main distribution channel. Compared to the music industry, the video game industry was more successful in adapting its business models and therefore is a vital source from which to draw analogies for the music industry. In this article we propose a cross-industry innovation on the basis of a business model taken from the video game industry adapted to the needs of the market for digital music. This is illustrated with a case-study of the UK music-technology startup RjDj.

There are large scientific data archives manage and store huge quantities of data, deal with this data throughout its life cycle, and focus on particular scientific domains. These scientific data is usually generated by specific devices or sensors. While the number of sensed data file is daily increased, utilizing an efficient to access daily-incremental data set is increasing important. In this paper, we propose a DHT-based (Distributed Hash Table) data extraction scheme to speedup data extraction for geographical ocean data. We conduct some experiments to evaluate the performance of the proposed approach and make a comparison with traditional approach and existing system. It shows that the proposed approach is better in terms of performance.

Polymer database (PoLyInfo) provides various data required for polymeric materials design. The main data source is academic papers on polymers. PoLyInfo collects information on polymer names, chemical structures, processing methods of samples, measurement conditions, properties, used monomers and polymerization methods. PoLyInfo continues the expansion of data as one of NIMS materials database. This paper presents system architecture of "Polymer database (PoLyInfo)" and its distinctiveness. And we also report usage survey of our system.

In many industries, large amounts of resources are allocated for continuous technology development. However, these investments may prove inefficient if a disruptive technology arises that provides new and more attractive customer propositions. While this phenomenon has been the subject of numerous papers, there is still a lack of managerial tools that properly address the challenge of responding to this threat. This paper provides an updated review of recent developments in the field and, furthermore outlines a tool that supports managers in identifying forthcoming disruptive technologies and providing them with tailored strategic options. The application of this approach is illustrated by means of a case study on mass-market voice services.

The traditional model of public administration is becoming obsolete and need to be redesigned to fulfill the new society requirements, using the benefits brought by the evolution of technology. e-Services represent the transposition of the traditional public services in the virtual world. This paper proposes a solution for the academic environment at the University POLITEHNICA of Bucharest, taking into consideration the issuance of an academic diploma. The solution is based on workflows, the best choice when implementing e-services. The paper focuses on analyzing and optimizing parameters like: scalability, accessibility, efficiency, usability and also on security challenges.

Large Web sites contain a plethora of different menus and navigation aids, which implement systems of content organization as hierarchies, linear structures or matrices. Humans are able to decode the fine-grained content organization because they are aware of the different access methods provided by navigation systems and understand the higher-level information architecture. In contrast, current methods of link analysis cannot extract such a detailed model of the information architecture and are not able to recognize site boundaries and content hierarchies the way humans do. In this paper present a new approach of mining navigation systems that increases the precision of Web structure mining. Instead of analyzing the complete Web graph spanned by pages and hyperlinks, sub graphs called Navigation Structure Graphs (NSGs) are analyzed. A NSG represents the hyperlinks belonging to a certain navigation system. We demonstrate the capabilities of NSGs for analyzing the organization of Web sites and present our research on mining NSGs.

Recent large-scale disasters and territorial emergencies, such as the Japan seaquake and Australian inundation, have brought to the attention the efficiency of the rescue operation. Such scenarios are unpredictable and require a prompt and coordinated reaction from the authorities. This paper presents an architectural approach for coordination and cooperation based on the Multi-Agent technology. In the following, we will show how agents are able to offer a distributed, context-aware, reactive and autonomous support. We propose a Multi-Agent framework that enables the implementation of Multi-Agent Systems (MAS) for emergency scenarios management.
