The emerging Semantic Web and, in particular, Semantic Web services (SWS), demands the inclusion of new components in applications involving this technology. Therefore, Web development methodologies must be tailored to support the systematic development of such new components. In previous works we presented a UML profile, which extends the SOD-M method for service oriented Web Information System development of the MIDAS model-driven framework, to address the development of Semantic Web Services using WSMO (Web Service Modeling Ontology). The UML profile allows for the modeling of the new elements required by WSMO Web Services. This article focuses on studying the possibility of improving the proposed UML profile, including the OCL (Object Constraint Language), for the representation of WSMO logical axioms through three case studies. This would allow developers, whose knowledge does not extend beyond UML, to develop applications that use Semantic Web services.

This article discusses the main security requirements for Web services and it describes how such security requirements are addressed by standards for Web services security recently developed or under development by various standardizations bodies. Standards are reviewed according to a conceptual framework that groups them by the main functionalities they provide. Covered standards include most of the standards encompassed by the original Web Service Security roadmap proposed by Microsoft and IBM in 2002 (Microsoft and IBM 2002). They range from the ones geared toward message and conversation security and reliability to those developed for providing interoperable Single Sign On and Identity Management functions in federated organizations. The latter include Security Assertion Markup Language (SAML), WS-Policy, XACML, that is related to access control and has been recently extended with a profile for Web services access control; XKMS and WS-Trust; WS-Federation, Liberty Alliance and Shibboleth, that address the important problem of identity management in federated organizations. The article also discusses the issues related to the use of the standards and open research issues in the area of access control for Web services and innovative digital identity management techniques are outlined.

Cloud computing is one of the strategic technology trends. It’s pay as you go characteristic and the fact that the service is provided via a broad network, such as a web browser is what makes cloud providers incentivised by profits by providing cloud services, and cloud customers are interested in the chance of eliminating costs that come with in-house service provision. Due to its infrastructure where cloud providers maintain everything cloud customers are wary and concerned about their data and system security. Hence this paper was tries to address and answer cloud customers’ concern on security by doing an overall risk analysis using ENISA framework and Commonwealth of Virginia risk assessment guide on XYZ Web App, an application provided by XYZ Company for the insurance industry that connects insurers, repairers, adjusters and other third parties for claim processing and policy creation. This paper answers all the concerns by resulting it in overall risk summaries, likelihood, impact and overall risk rating that later in used for recommendation to improve XYZ Web App security.

The web and converged services paradigm promises tremendous flexibility in the creation of rich composite services for enterprises and end users. The flexibility and richness offers the possibility of highly customized, individualized services for the end user and hence revenue generating services for service providers (e.g. ASPs, telecom network operators, ISPs). But how can end users (and enterprises) specify their preferences when a myriad of possibilities and potential circumstances need to be addressed? In this paper, we advocate a solution based on policy management where user preferences are specified through forms but translated into rules in a high-level policy language. This paper identifies the requirements for this kind of interpretation, and describes the Houdini system (developed at Bell Labs) which offers a rich rule-based language and a framework that supports intuitive, forms-based provisioning interfaces.

Full textAbstract:
Current e-Health portal platforms provide support for patients only if they have previously registered and received service from a healthcare facility (e.g., hospital, healthcare clinic, etc.). These portals are usually connected to a central EMR/EHR system linked to a central system. Furthermore, these portals are restrictive in that they are only accessible by these patients at the exclusion of parents, relatives and others that participate in providing care to the patient. Further complications include the increasing demand from our healthcare systems for patients to receive more off-site, non-primary, in-homecare, and/or specialized healthcare services at home (e.g., therapy, nursing, personal support, etc.). Lastly, an increasing number of people would like to have more autonomy over their health in terms of increased access to their own medical records and the services they receive. In this work, we addressed these limitations by creating MyHealthPortal – a patient portal aimed at non-primary care, in-homecare, and/or special healthcare for patients. MyHealthPortal can assist homecare and clinic-based healthcare services along with the benefits of existing portals (e.g., online appointment scheduling, monitoring, and information sharing). MyHealthPortal is secure, robust, flexible and user-friendly. We developed it in partnership with our industry partner, Closing the Gap Healthcare. Closing the Gap is a prominent homecare and clinic-based healthcare service provider that became the first homecare agency to score 100% on standards from accreditation Canada and was awarded the exemplary standing. In this paper we present MyHealthPortal, the architectural framework that we designed and developed to support the system, and the results of a usability study conducted from real field studies. Our system was tested in a variety of conditions and achieved SUS usability scores of 92.5% (high).

• Summary: Domestic violence agency administrators struggle to incorporate the Internet safely and effectively into their intimate partner violence (IPV) services. This study utilizes two data gathering tools to identify administrative concerns and web content in the 91 Texas shelters. The first research stage employed a mixed-methods questionnaire (89% response rate) to identify managers’ Internet use patterns and managerial needs. In the second stage, all shelter web sites (65) were submitted to a multi-context content analysis. • Findings: Overall, findings indicate that administrators see a serious need for basic administrative support tools (e.g. policies and training materials) and the development of cyber-safety resources (e.g. online stalking tips). Administrators view the Internet’s potential for increasing staff efficiency and clients’ sense of self-efficacy as worthwhile. Questionnaire findings indicate that 66 percent of directors need a means of helping clients learn to do their own information-seeking, only 54 percent have a written policy, and 46 percent have no in-house training at all. Web site findings indicate that 61 percent of the sites lacked minimal cyber-safety information despite administrative concerns about cyber-stalking. • Applications: IPV shelter administrators’ two Internet utility criteria, service priorities and resources, privilege implementation barriers and ignore the embedded expectations of communication and resource support. By shifting from a shelter-based Internet perspective to a user-generated perspective, administrators can integrate clients’ expectations with the shelter’s options. The resultant conceptual framework for Internet integration posits the lived information experience as managers’ basis for shaping social communication, resource generation, information seeking, and decision-making.

Full textAbstract:
Summary The huge and dynamic amount of bioinformatic resources (e.g., data and tools) available nowadays in Internet represents a big challenge for biologists -for what concerns their management and visualization- and for bioinformaticians -for what concerns the possibility of rapidly creating and executing in-silico experiments involving resources and activities spread over the WWW hyperspace. Any framework aiming at integrating such resources as in a physical laboratory has imperatively to tackle -and possibly to handle in a transparent and uniform way- aspects concerning physical distribution, semantic heterogeneity, co-existence of different computational paradigms and, as a consequence, of different invocation interfaces (i.e., OGSA for Grid nodes, SOAP for Web Services, Java RMI for Java objects, etc.). The framework UBioLab has been just designed and developed as a prototype following the above objective. Several architectural features -as those ones of being fully Web-based and of combining domain ontologies, Semantic Web and workflow techniques- give evidence of an effort in such a direction.The integration of a semantic knowledge management system for distributed (bioinformatic) resources, a semantic-driven graphic environment for defining and monitoring ubiquitous workflows and an intelligent agent-based technology for their distributed execution allows UBioLab to be a semantic guide for bioinformaticians and biologists providing (i) a flexible environment for visualizing, organizing and inferring any (semantics and computational) “type” of domain knowledge (e.g., resources and activities, expressed in a declarative form), (ii) a powerful engine for defining and storing semantic-driven ubiquitous in-silico experiments on the domain hyperspace, as well as (iii) a transparent, automatic and distributed environment for correct experiment executions.

<p><strong>Abstract.</strong> Spatio-temporal big data cloud platform is an important spatial information infrastructure that can provide different period spatial information data services, various spatial analysis services and flexible API services. Activities of policy coordination, facilities connectivity and unimpeded trade on the Belt and Road Initiative (B&R) will create huge demands to the spatial information infrastructure. This paper focuses on researching a distributed spatio-temporal big data engine and an extendable cloud platform framework suits for the B&R and some key technologies to implement them. A distributed spatio-temporal big data engine based on Cassandra&trade; and an extendable 4-tier architecture cloud platform framework is put forward according to the spirit of parallel computing and cloud service. Four key technologies are discussed: 1) a storage and indexing method for distributed spatio-temporal big data, 2) an automatically collecting, processing, mapping and updating method of authoritative spatio-temporal data for web mapping service, 3) a schema of services aggregation based on nodes registering and services invoking based on view extension, 4) a distributed deployment and extension method of the cloud platform. We developed a distributed spatio-temporal big data centersoftware and founded the main node platform portal with MapWorld&trade; map services and some thematic information services inChina and built some local platform portals for those countries in the B&R area. The management and analysis services for spatio-temporal big data were built in flexible styles on this platform. Practices show that we provide a flexible and efficient solution tobuild the distributed spatio-temporal big data center and cloud platform, more node portals can be aggregated to the main portal bypublishing their own web services and registering them in the aggregation schema. The data center and platform can support thestorage and management of massive data well and has higher fault tolerance and better scalability.</p>

Full textAbstract:
Dynamic selection and composition of autonomous and loosely-coupled Web services is increasingly used to automate business processes. The typical long-running characteristic of business processes imposes new management challenges such as dynamic adaptation of running process instances. However, current process orchestration engines provide limited flexibility to dynamically adapt to changing runtime conditions (e.g., presence of faults). Additionally, current process specification languages exhibit some limitations regarding modularity of crosscutting management concerns. In particular, monitoring and adaptation logic is often scattered across several process definitions and intertwined with the business logic. This leads to monolithic and complex processes that are hard to understand, reuse, maintain, and evolve. To address these limitations, we developed a policy-based change management framework, named Manageable and Adaptable Service Compositions (MASC), to declaratively express crosscutting monitoring and process adaptation concerns in a separate and modular way. MASC policies use a set of simple, but flexible and relatively powerful, constructs to declaratively specify policies that govern: (1) discovery and selection of services to be used, (2) monitoring to detect the need for adaptation, (3) reconfiguration and adaptation of the process to handle special cases (e.g., context-dependant behaviour) and recover from typical faults in service-based processes. The identified constructs are executed by a lightweight service-oriented management middleware named MASC middleware. The adaptation is transparent because it preserves the original functional behaviour of the business process and does not tangle the adaptation logic with that of the business process. Additionally, policies do not have to be necessarily defined when designing the process; they can also be introduced later during deployment or at runtime. We implemented a MASC proof-of-concept prototype and evaluated it on Stock Trading case study scenarios. We conducted extensive studies to demonstrate the feasibility of the proposed techniques and illustrate the benefits of our approach in providing adaptive composite services using the policy-based approach. Our performance and scalability studies indicate that MASC middleware is scalable and the introduced overhead are acceptable.

Policies, which usually govern the behaviour of networking services (e.g., security, QoS, mobility, etc.) are becoming an increasingly popular approach for the dynamic regulation of web information systems. By appropriately managing policies, a system can be continuously adjusted to accommodate variations in externally imposed constraints and environmental conditions. The adoption of a policy based approach for controlling a system requires an appropriate policy representation regarding both syntax and semantics, and the design and development of a policy management framework. In the context of the Web, the use of languages enriched with semantics has been limited primarily to represent Web content and services. However the capabilities of these languages, coupled with the availability of tools to manipulate them, make them well suited for many other kinds of applications, as policy representation and management. In this chapter, we present an evaluation of the ongoing efforts to use ontological (Semantic Web) languages to represent policies for distributed systems.

Service-Oriented Computing (SOC), a main trend in software engineering, promotes the construction of applications based on the notion of services. SOC has recently attracted a great deal of attention from researchers, and has been comprehensively adopted by industry. However, service composition enabling the aggregation of existing services into composite services still imposes a great challenge to service-oriented technology. Web service composition requires component Web services to be available in request, to behave correctly in operation, and to be replaceable flexibly in failure. Although availability of Web services plays a crucial role in building robust SOC-based applications, it has been largely neglected, especially for service composition. In this chapter, we propose a service composition framework that integrates a set of composition-based service discovery mechanisms, a user-oriented service delivery approach, as well as a service management mechanism for composite services.

Maintenance aims to reduce and eliminate the number of failures occurred during production as any breakdown of machine or equipment may lead to disruption for the supply chain. Maintenance policy is set to provide the guidance for selecting the most cost-effective maintenance approach and system to achieve operational safety. For example, predictive maintenance is most recommended for crucial components whose failure will cause severe function loss and safety risk. Recent utilization of big data and related techniques in predictive maintenance greatly improves the transparency for system health condition and boosts the speed and accuracy in the maintenance decision making. In this chapter, a Maintenance Policies Management framework under Big Data Platform is designed and the process of maintenance decision support system is simulated for a sensor-monitored semiconductor manufacturing plant. Artificial Intelligence is applied to classify the likely failure patterns and estimate the machine condition for the faulty component.

Full textAbstract:
A critical issue in the choreographed services development is the conciliation of interaction protocol mismatches that affect the cooperation among the services to be integrated in the composite service. This chapter attempts to answer such an issue by presenting a mediation framework that supports the development and management of choreographed services by offering a loosely-coupled integration model and a flexible management of protocol mismatches. Such features are obtained by introducing (i) an action-based representation of the functions offered by a Web service; (ii) an explicit management of the state of the choreographed service, which determines the operations to be carried out in order to contribute to the service completion; (iii) an event-driven Web service execution model, which makes it possible to abandon the direct invocation of Web service operations in favour of an autonomous execution of actions, based on the available context information.

Services computing is developing towards complex, large-scale infrastructures referred to as the Internet of things and an Internet of services. Cloud computing supports hundreds of thousands of users and applications/services and ensures that these are available on demand, in a reliable and secure way. These infrastructures present many challenges to the design and implementation of systems to manage, protect and tune them. This chapter shows that in order to support the needed interoperability in these infrastructures, such systems must support adaptation based on service semantics and be capable of runtime autonomic behaviour. For engineering such systems, there is a strong need to build on and extend standard software architectures, in particular the service oriented architectures (SOA) and model driven service engineering approaches. Given these requirements, this chapter introduces a model driven approach to a runtime adaptable requirements driven services management system, and presents a theoretical framework building on intention models that are transformed in several steps to dynamic business processes complying with the Web services paradigm and the business process execution language for Web services. These services can be reconfigured at runtime by autonomic behaviours of the management system in line with the intention model. Within the Neptune framework introduced here, the needed modelling languages, model transformations and a runtime environment implementing such an approach are provided. The chapter closes with a case study based on the well known PetShop enterprise application blueprint. The study demonstrates in practice the autonomic adaptation to changes in the services requirements observed at runtime, and concludes with a section highlighting future applications and extensions of the approach.

Computerizing the country is a priority for the Italian government, which has set up the Digital Agenda for innovation driven by information and communication technologies to deliver smart, sustainable and inclusive growth, in adherence to European Union's policies. Cloud computing is one of the pillars of this strategic plan, since by accelerating the implementation of the Digital Agenda, it represents a chance for Italy to meet its increasingly crucial need for innovation and revitalization of competitiveness. Among the different solutions that Italian public administrations have been adopting, sustainable cloud computing frameworks have been chosen, with minimal management effort, for their contribution to smart working, and their capability of reconciling economic demands, environmental resilience, and social equity. This chapter aims to explore the ongoing change in the technological architecture for e-Government in Italian municipalities and the effects of the activation of sustainable cloud computing frameworks for this purpose, with particular emphasis on personnel's empowerment. On the basis of the benchmarking of the best practices, recommendations will be provided for an effective implementation of Google Apps as a sustainable cloud computing solution to foster staff's continuing professional and personal development in Italian municipalities.

Today’s design environment has become more distributed and professional. Efficient design management can greatly improve the ability of a company’s competition. To increase efficiency of a design process coordination of Computer-Aided Design and Analysis tools are very important, especially for large complicated systems. In this paper, we introduce the concept of a requirement driven system. Design process usually involves fulfillment of requirements from top-end customer. Adopting requirement driven mechanisms will provide more convenience for design coordination automation and help us find the most resource saving solutions for specific product design. A CORBA framework is discussed to facilitate the implementation of methodologies for requirement driven design coordination. System architecture and modules for the framework are introduced to support a requirement publishing and responding service. Distribution of the tasks is determined by “stigmergy” algorithm, which makes the decision using the performance history of each team and designers. An example of a coffeemaker product design based on the framework, is presented to demonstrate the application of new design system.

Abstract Mobility is no longer just a necessity for travelers, but choices among several possible routes and transportation modes. Urban passenger rail transport plays an essential role because it is affordable, convenient, safe, and fast. On the other hand, rail lines are limited to high passenger density corridors. Inevitably, rail has to be placed together with different transport modes, forming a multimodal network. However, to enable this integration with other modes of transport, numerous practical problems remain, such as making a smooth transition from the existing siloed, mode specific operational structure towards an interconnected system of transportation modes and business models for a seamless connected journey. The current isolated operational structure lacks a single truth and accurate visibility, which further discourages participation from augmenting transportation modes and leads to the extended reaction time for new technology integration. This research article introduces a Multimodal Mobility (MMM) solution framework that provides a functional interface to integrate and synchronize the railroad operations with other public transit networks (including train-bus-rapid transits) and micro-mobility services. The known approach to addressing the users’ seamless mobility experience entails a centralized, prearranged, a priori knowledge and mechanism for operating intermodal transport systems. In contrast, the method defined in this paper focuses on a market-driven demand-responsive system that allows for dis-intermediation in a network of peer-level transportation modes operations. The framework facilitates blockchain-based decentralized and multi-organizational engagement. The focus here is the role of railroad in the multimodal ecosystem and its performance advancements in this integrated solutions framework. Leveraging a combination of graph analytics and machine learning algorithms, we provide methods to address challenges in encoding spatial and temporal dependencies of multimodal transit networks and handle complex optimization problems such as mixed time window and volume variation for resource allocation and transit operational analytics. This enables operation of different transit modes with varied resolution and flexibility for operational parameters like time, capacity, ridership, revenue management, etc. The analytics enable solutions for recommendations on synchronizing and integrating operations of transportation systems. Further, the network’s decentralization and modular handling enable market-driven co-optimization of operational resources across various transportation modes to ensure seamless transit experience for users.

In Latin American cities informal settlements and insecure land tenure are the result of an exclusionary planning and urban management system which fails to provide legal and secure housing for lower-income groups. Against this backdrop, the State implemented land-title and urban regulatory policies, in order to improve the housing conditions of these neighbourhoods and integrate their residents into the legal regime. This paper proposes to address the conflicts implied in the processes of urbanization and regularization of the villas of the city of Buenos Aires during the first government of Rodríguez Larreta (2015-2019). In the official political discourse, the urbanization of informal settlements is considered one of the main axes of local management. Within this framework, institutional changes are being carried out, such as the creation of the Ministry of Social and Urban Integration. This report proposes to address the participation implied in the process of urbanization and regularization of Villa 20 in the Autonomous City of Buenos Aires. This process have raised many challenges in the interaction between government decision-making and the needs of inhabitants of informal settlement. These challenges are linked to a) the democratic participation of the inhabitants in the decision-making process at all stages, b) land management policies and domain regularization; c) the modalities and logic of relocation of inhabitants; d) the provision and access to infrastructure services and public spaces; e) the treatment of tenants and other more vulnerable groups. Based on the analysis of the case study, we propose to account for the limits and scope of the implemented urbanization policy as well as for the opportunities to expand the horizon of tools and intervention modalities promote the right to the city and reduce territorial inequalities

The Amazon biome, despite its resilience, is being pushed by unsustainable economic drivers towards an ecological tipping point where restoration to its previous state may no longer possible. This is the result of self-reinforcing interactions between deforestation, climate change and fire. In this paper, we develop scenarios that represent movement towards an Amazon tipping point and strategies to avert one. We assess the economic, natural capital and ecosystem services impacts of these scenarios using the Integrated Economic-Environmental Modeling (IEEM) Platform linked with high resolution spatial land use land cover change and ecosystem services modeling (IEEMESM). This papers main contributions are developing: (i) a framework for evaluating strategies to avert an Amazon tipping point based on their relative costs, benefits and trade-offs, and; (ii) a first approximation of the economic, natural capital and ecosystem services impacts of movement towards an Amazon tipping point, and evidence to build the economic case for strategies to avert it. We find that a conservative estimate of the cumulative regional cost through 2050 of an Amazon tipping point would be US$256.6 billion in Gross Domestic Product. Policies that would contribute to averting a tipping point, including strongly reducing deforestation, investing in climate-adapted agriculture, and improving fire management, would generate approximately US$339.3 billion in additional wealth. From a public investment perspective, the returns to implementing strategies for averting a tipping point would be US$29.5 billion. Quantifying the costs, benefits and trade-offs of policies to avert a tipping point in a transparent and replicable manner can pave the way for evidence-based approaches to support policy action focusing on the design of regional strategies for the Amazon biome and catalyze global cooperation and financing to enable their implementation.
