In this chapter we provide an overview of electronic government as it pertains to national security and defense within the Department of Defense (DoD) and Department of Homeland Security (DHS). We discuss the adoption of web services and service oriented architectures to aid in information sharing and reduction of Information Technology (IT) costs. We also discuss the networks on which services and resources are being deployed and explain the efforts being made to manage the infrastructure of available services. This chapter provides an overview of e-government for national security and defense and provides insight to current initiatives and future directions.

National Security State

In response to the terrorist attacks of 1993 and 2001, the Clinton and Bush administrations restructured the immigration bureaucracy, placed it within the new Department of Homeland Security, and tried to convey to Americans a greater sense of safety. Refugees, especially those from Iraq, Afghanistan, and Syria, suffered the consequences of the new national security state policies, and found it increasingly difficult to find refuge in the United States. In the post-9/11 era, refugee advocates became even more important to the admission of refugees, reminding Americans of their humanitarian obligations, especially to those refugees who came from areas of the world where US foreign policy had played a role in displacing populations.

Service-Oriented Architectures (SOA) enable the automatic creation of business applications from independently developed and deployed Web services. As Web services are inherently a priori unknown, how to deliver reliable Web services compositions is a significant and challenging problem. Services involved in an SOA often do not operate under a single processing environment and need to communicate using different protocols over a network. Under such conditions, designing a fault management system that is both efficient and extensible is a challenging task. In this article, we propose SFSS, a self-healing framework for SOA fault management. SFSS is predicting, identifying, and solving faults in SOAs. In SFSS, we identified a set of high-level exception handling strategies based on the QoS performances of different component services and the preferences articled by the service consumers. Multiple recovery plans are generated and evaluated according to the performance of the selected component services, and then we execute the best recovery plan. We assess the overall user dependence (i.e., the service is independent of other services) using the generated plan and the available invocation information of the component services. Due to the experiment results, the given technique enhances the service selection quality by choosing the services that have the highest score and betters the overall system performance. The experiment results indicate the applicability of SFSS and show improved performance in comparison to similar approaches.

Highly developed economies are based on the knowledge society. A variety of software tools are used in almost every aspect of human life. Service-oriented architectures are limited to corporate-related business solutions. This chapter proposes a novel approach aimed to overcome the differences between real life services and software services. Using the design approaches for the current service-oriented architecture, a solution that can be implemented in open source systems has been proposed. As a result, a new approach to creating an agent for service composition is introduced. The agent itself is created by service composition too. The proposed approach might facilitate the research and development of Web services, service-oriented architectures, and intelligent agents.

Core Directories are content infrastructure elements for interoperable use in service oriented architectures. They capsulate basic information to a generic structure offering easy access and transparency. The design and research activities focused on specification, a generic approach, globally unique identification of objects and development of an example application. Moreover, requirements and advantages of the concept were discussed and directed to information management issues. Key objective is the modernisation of the information technology used in and between administrations. The interdisciplinary approach is a challenge for the constitution of next generation e-Government networks. The chapter describes the strategic and operative standardisation activities, the concept of Core Directories and the example application service responsibility finder. Furthermore, an outlook for some research activities and projects on this topic is given.

In this data-centric world, as web services and service oriented architectures gain momentum and become a standard for data usage, there will be a need for tools to automate data retrieval. In this paper we propose a tool that automates the generation of joins in a transparent and integrated fashion in heterogeneous large databases as well as web services. This tool reads metadata information and automatically displays a join path and a SQL join query. This tool will be extremely useful for performing joins to help in the retrieval of information in large databases as well as web services.

Given the critical and difficult nature of discovering Web services in the development process of service oriented architectures, several studies have been proposed to solve this problem. There is a real need to work for matching semantic Web services which use different ontologies. In responding to this need, measuring semantic similarity between SWS may be reduced to the calculation of similarity between ontological concepts. This work is a contribution to achieve semantic interoperability for Web services in a multi-ontology environment, for which the authors present a generic framework for Web services discovery. Here their focus is on the semantic similarity measure-based core of their framework and the authors present a novel algorithm for concepts matching between different ontologies. Results of the experiments confirm the viability of the semantic similarity measure.
