Abstract:
Purpose One of the open questions is how to ensure the conceptual adaptation in the pervasive system. To answer this question, the authors needed to propose a generic model and a mechanism to describe this system and also need generic and semantic rules to ensure the adaptation. This paper aims to propose a model to describe the pervasive information system. Second, the authors suggest an approach to divide this model so as to describe each category of contextual information separately and ensure the adaptation in the pervasive system. Finally, the authors present examples of semantic rules executed in the pervasive system. Design/methodology/approach This paper proposes an approach to ensure the conceptual adaptation in the pervasive system. To do it, the authors proposed a model to design the pervasive system and used semantic Web services. They proposed to divide the model to six descriptions related to the pervasive system categories information. Findings Pervasive information system, conceptual adaptation, semantic Web services and OWL-S are presented in this paper. Originality/value The originality of this paper is presented in the purpose of the pervasive information system conceptual adaption in the pervasive system. In this, later, semantic Web services were used to ensure the adaptation by the adding of contextual information in the semantic Web service description.

Abstract:
Software is gradually becoming more built by composing web services to support enterprise applications integration; thus, making the process of composing web services a significant topic. The Quality of Service (QoS) in web service composition plays a crucial role. As such, it is important to guarantee, monitor, and enforce QoS and ability to handle failures during execution. Therefore, an urgent need exists for a dynamic Web Service Composition and Execution (WSCE) framework based on QoS constraints. A WSCE broker is designed to maintain the following function: intelligent web service selection decisions based on local QoS for individual web service or global QoS based selection for composed web services, execution tracking, and adaptation. A QoS certifier controlled by the UDDI registry is proposed to verify the claimed QoS attributes. The authors evaluate the composition plan along with performance time analysis.

This paper proposes an exception handling mechanism based on Adaptation Planning Graph for service-based business processes. A three-layer representation model of service-based business process is introduced firstly. And then, Logic Model of Service-based Business Process and Adaptation Planning Graph are introduced to enforce reliability of composite Web Services at run-time. Simulations prove that this approach can efficiently guarantee the reliability of composite services at run-time.

Abstract:
The aim of Web services is the provision of software services to a range of different users in different locations. Service localisation in this context can facilitate the internationalisation and localisation of services by allowing their adaption to different locales. The authors investigate three dimensions: (i) lingual localisation by providing service-level language translation techniques to adopt services to different languages, (ii) regulatory localisation by providing standards-based mappings to achieve regulatory compliance with regionally varying laws, standards and regulations, and (iii) social localisation by taking into account preferences and customs for individuals and the groups or communities in which they participate. The objective is to support and implement an explicit modelling of aspects that are relevant to localisation and runtime support consisting of tools and middleware services to automating the deployment based on models of locales, driven by the two localisation dimensions. The authors focus here on an ontology-based conceptual information model that integrates locale specification into service architectures in a coherent way.

Abstract:
Internet of Services (IoS) vision allows users to allocate and consume different web services on the fly without any prior knowledge regarding the chosen services. Such chosen services should automatically interact with one another in a transparent manner to accomplish the required users' goals. As services are chosen on the fly, service conversations are not necessarily compatible due to incompatibilities between services signatures and/or conversation protocols, creating obstacles for realizing the IoS vision. One approach for overcoming this problem is to use conversation adapters. However, such conversion adapters must be automatically created on the fly as chosen services are only known at run time. Existing approaches for automatic adapter generation are syntactic and very limited; hence they cannot be adopted in such dynamic environments. To overcome such limitation, this paper proposes a novel approach for automatic adapter generation that uses conditional substitution semantics between application domain concepts and operations to automatically generate the adapter conversion functions. Such conditional substitution semantics are captured using a concepts substitutability enhanced graph required to be part of application domain ontologies. Experiments results show that the proposed approach provides more accurate conversation adaptation results when compared against existing syntactic adapter generation approaches.

Abstract:
Service Oriented Architecture is a software design paradigm of choice for building and integrating distributed Information Systems. The greatest challenge of SOA is to make the system more flexible and adaptable to the enterprise and user environment changes. However, services can change constantly. These changes are produced due to adjustment in structure, e.g., changing service signature, integrating new services into existing business services; in behavior e.g., adding new business rules in simple or composite services; and in interaction schema between the services and the clients. This paper presents a solution based on service component concepts for dealing with changes confined to services and clients in SOA-based applications. It uses service components concepts to define adaptable services that facilitate the extension and the customization of existing services in harmony with service users. In addition, it presents an adaptation service-oriented lifecycle scenario to control service changes in the entire service lifecycle ranging from the announcement to the execution phase

Abstract:
Due to the inherent stochastic nature of services execution environment within service oriented systems, a runtime adaptation of the given composition may be required. The authors investigate a runtime service adaptation mechanism based on conditional retries for orchestrated web services. The conditional retry may be issued while a concrete service within composition is executed. The retry could either invoke the same concrete service or a functionally equivalent web service that implements the same task. The authors use dynamic programming to determine the optimal time instances at which the current request should be terminated before request replication. The calculation takes into account different QoS parameters like services' response-time distributions and cost-related parameters, and the solution optimizes the expected revenue of the composite service provider. The authors illustrate the benefits of their approach by numerical calculations, and discuss the impact of considered QoS parameters to the solution at hand.

Abstract:
<p><strong>Abstract.</strong> <strong>The problem</strong> discussed in this research is connected with the functionality of the graphical user interface (GUI) of global web mapping services displayed on different devices. Displaying a mapping service on devices with diverse display screen size causes the adaptation of the graphical user interface to the size of the screen. This adaptation is the result of the responsive design technique which enables one to display the same web content on different devices. Eight global web mapping services: Google Maps, Bing Maps, OpenStreetMap (OSM), Baidu Maps, Yandex Maps, 2GIS, MapQuest, and HERE WeGo, constituted the source of the data. All of them were displayed on four display screens: the monitor of a personal computer, laptop, tablet, and smartphone in order to compare the similarities in the adaptation of GUI, its functions and map content.</p><p><strong>The aim of the research</strong> conducted was to find different solutions for displaying GUI of the same mapping service on diverse display screens of various devices and to track which functions are the most common and how they differ in terms of graphics.</p><p><strong>Methodology</strong> of the research is based on the comparative analysis of eight global web mapping services in terms of the number of GUI buttons, their layout, graphic style, the map functionality, and map content displayed on four devices of different display screen size.</p><p><strong>The results</strong> showed that most of the global web mapping services adapt to the device and their way of use. Some of them are also responsive in the context of external conditions. Interestingly, the adaptation between the PC monitor, laptop and tablet occurs only by changing the size of GUI buttons, other functions remaining the same. Only in the case of smartphones GUI adapts to the size of the device, the number of buttons decreases and their layout changes, new functionality is available (e.g. day/night mode), and the map content is more generalized. On that basis, authors concluded that GUI of global map services constituted a good example of responsive web design.</p>

Full text
Abstract:
WS-agreement specifies quality objectives that each partner is obligated to provide. To meet quality objectives, the corresponding partner should apply appropriate policy assertions to its web services and adjust their parameters accordingly. Transformation of WS-CDL to WSBPEL is addressed in some related works, but neither of them considers quality aspects of transformation nor run-time adaptation. Here, in conformance with web services standards, we propose an optimal decomposition method to make a set of WS-policy assertions. Assertions can be applied to WSBPEL elements and affect their run-time behaviors. The decomposition method achieves the best outcome for a performance indicator. It also guarantees the lowest adaptation overhead by reducing the number of service reselections. We considered securities settlement case study to prototype and evaluate the decomposition method. The results show an acceptable threshold between customer satisfaction—the targeted performance indicator in our case study—and adaptation overhead.

Abstract:
Purpose – The purpose of this paper is to examine whether cultural backgrounds of nations are expressed through the web design of their companies. Actually, it investigates whether, in countries characterized by the same cultural matrix and language but by different national backgrounds, the cultural specificities of a country are a critical success factor for web design and enablers of business excellence. Design/methodology/approach – Starting from a deep literature review, four research hypotheses on the relationship between cultural background and web design are formulated. By employing both the content analysis and the cross-tabulation methodology, these hypotheses are tested. Findings – Brazilian, Portuguese, Angolan and Macanese web sites show that companies operating in these countries are aware that cultural background is a necessary success factor to consider for improving cross-cultural management of computer-mediated communication. Indeed, the findings confirm that the internet is not a culturally neutral communication medium. By providing evidences of web site cultural adaptation, this study supports the use of a targeted approach to web site design and provides managerial guidelines for improving business excellence of companies’ online environment. Originality/value – The paper offers insights into the topic of a culturally adapted computer-mediated communication for improving consumer experience.

This paper presents a Service Oriented Architecture (SOA)-based content delivery model to facilitate mobile content delivery. The main contribution of this paper is the design and development of an SOA-equipped content delivery system based on a context-driven, access-controlled, profile-favored, and history-maintained (CAPH) model. We embody the generic model-view-controller (MVC) model to support a dynamic content adaptation technique based on mobile users' contextual environments. Self-adaptable presentation objects and modules are modeled as universal Web services resources, so that their interactions are formalized into Web services operations for high interoperability. Experimental results demonstrate that our proposed SOA-based model makes it easy to configure and construct a flexible Web content delivery system on the mobile Internet.

Abstract:
This article presents our design and development of a description logics-based planner for providing contextdriven content adaptation services. This approach dynamically transforms requested Web content into a proper format conforming to receiving contexts (e.g., access condition, network connection, and receiving device). Aiming to establish a semantic foundation for content adaptation, we apply description logics to formally define context profiles and requirements. We also propose a formal Object Structure Model as the basis of content adaptation management for higher reusability and adaptability. To automate content adaptation decision, our content adaptation planner is driven by a stepwise procedure equipped with algorithms and techniques to enable rule-based context-driven content adaptation over the mobile Internet. Experimental results prove the effectiveness and efficiency of our content adaptation planner on saving transmission bandwidth, when users are using handheld devices. By reducing the size of adapted content, we moderately decrease the computational overhead caused by content adaptation.

Abstract:
We are on the threshold of a mediamorphosis that will revolutionize the way we interact with our TV sets. The combination between interactive digital TV (IDTV) and the Web fosters the development of new interactive multimedia services enjoyable even through a TV screen and a remote control. Yet, several design constraints complicate the deployment of this new pattern of services. Prominent unresolved issues involve macro-problems such as collecting information on the Web based on users' preferences and appropriately presenting retrieved Web contents on the TV screen. To this aim, we propose a system able to dynamically convey contents from the Web to IDTV systems. Our system presents solutions both for personalized Web content search and automatic TV-format adaptation of retrieved documents. As we demonstrate through two case study applications, our system merges the best of IDTV and Web domains spinning the TV mediamorphosis toward the creation of the personal-TV concept.

In most existing E-learning systems, activities' content and order are presented in a static manner without taking into consideration the learners characteristics, profiles or competencies. The challenge is to adapt and regulate learning processes according to the learner profile by applying learning models that use new information technologies. There are several adaptation approaches of E-learning environments, such as, adaptive hypermedia system, semantic web, etc. In our proposed system, we adopted a Competency Based Approach to offer each learner an individualized learning path for the acquisition of the competence targeted on the basis of the collaborative filtering. Concerning the technological aspect, the system is implemented as a web services while adhering to a service-oriented architecture. This allows interoperability with heterogeneous learning systems

Abstract:
Reducing the size of the wirelessly transmitted data during the invocation of third-party Web services is a worthwhile goal of many mobile application developers. Among many adaptation mechanisms that can be used for the mediation of such Web service invocations, the automated enhancement of caching mechanisms is a promising approach that can spare the re-transmission of entire content fields of the exchanged messages. However, it is usually impeded by technological constraints and by various other factors, such as the inherent risk of using responses that are not fresh, i.e., are not up-to-date. This paper presents the roadmap, the most important technical and algorithmic details, and a thorough evaluation of the first solution for generically and automatically enriching the communication with any third-party Web service in a way that cached responses can be exploited while a freshness of 100% is maintained.

Abstract:
In order to measure and classify odors, Quartz Crystal Microbalance (QCM) can be used. In the present study, seven QCM sensors and three different odors are used. The system has been developed as a virtual organization of agents using an agent platform called PANGEA (Platform for Automatic coNstruction of orGanizations of intElligent Agents). This is a platform for developing open multi-agent systems, specifically those including organizational aspects. The main reason for the use of agents is the scalability of the platform, i.e. the way in which it models the services. The system models functionalities as services inside the agents, or as Service Oriented Approach (SOA) architecture compliant services using Web Services. This way the adaptation of the odor classification systems with new algorithms, tools and classification techniques is allowed.

Abstract:
Emerging Internet of Things (IoT)/Machine-to-Machine (M2M) systems require a transparent access to information and services through a seamless integration into the Future Internet. This integration exploits infrastructure and services found on the Internet by the IoT. On the one hand, the so-called Web of Things aims for direct Web connectivity by pushing its technology down to devices and smart things. On the other hand, the current and Future Internet offer stable, scalable, extensive, and tested protocols for node and service discovery, mobility, security, and auto-configuration, which are also required for the IoT. In order to integrate the IoT into the Internet, this work adapts, extends, and bridges using IPv6 the existing IoT building blocks (such as solutions from IEEE 802.15.4, BT-LE, RFID) while maintaining backwards compatibility with legacy networked embedded systems from building and industrial automation. Specifically, this work presents an extended Internet stack with a set of adaptation layers from non-IP towards the IPv6-based network layer in order to enable homogeneous access for applications and services.

Abstract:
Cloud computing technology has opened an avenue to meet the critical need to securely share distributed resources and web services, and especially those that belong to clients who have sensitive data and applications. However, implementing crosscutting concerns for cloud-based applications is a challenge. This challenge stems from the nature of distributed Web-based technology architecture and infrastructure. One of the key concerns is security logic, which is scattered and tangled across all the cloud service layers. In addition, maintenance and modification of the security aspect is a difficult task. Therefore, cloud services need to be extended by enriching them with features to support adaptation so that these services can become better structured and less complex. Aspect-oriented programming is the right technical solution for this problem as it enables the required separation when implementing security features without the need to change the core code of the server or client in the cloud. Therefore, this article proposes a Runtime Reusable Weaving Model for weaving security-related crosscutting concerns through layers of cloud computing architecture. The proposed model does not require access to the source code of a cloud service and this can make it easier for the client to reuse the needed security-related crosscutting concerns. The proposed model is implemented using aspect orientation techniques to integrate cloud security solutions at the software-as-a-service layer.

Abstract:
Ubiquitous Computing promises seamless access to a wide range of applications and Internet-based services from anywhere, at anytime, and using any device. In this scenario, new challenges for the practice of software development arise: Applications and services must keep a coherent behavior, a proper appearance, and must adapt to a plenty of contextual usage requirements and hardware aspects. Especially, due to its interactive nature, the interface content of Web applications must adapt to a large diversity of devices and contexts. In order to overcome such obstacles, this work introduces an innovative methodology for content adaptation of Web 2.0 interfaces. The basis of our work is to combine static adaption — the implementation of static Web interfaces; and dynamic adaptation — the alteration, during execution time, of static interfaces so as for adapting to different contexts of use. In hybrid fashion, our methodology benefits from the advantages of both adaptation strategies — static and dynamic. In this line, we designed and implemented UbiCon, a framework over which we tested our concepts through a case study and through a development experiment. Our results show that the hybrid methodology over UbiCon leads to broader and more accessible interfaces, and to faster and less costly software development. We believe that the UbiCon hybrid methodology can foster more efficient and accurate interface engineering in the industry and in the academy.

Abstract:
Today, in the development of information systems, cloud technologies are often used for remote computing and data processing. There are web technologies, and on their basis, libraries and frameworks have been developed for creating web applications and user interfaces designed for the operation of information systems in browsers. Ready-made JavaScript libraries have been developed to add drag and drop functionality to a web application. However, in some situations, the library may not be available, or there may be overhead or dependencies that the project does not need to use it. In such situations, an alternative solution provides the functionality of APIs available in modern browsers. The article discusses the current state of the methods of the Drag and Drop mechanism and proposes a programmatic way to improve the interface by creating a class for dragging and dropping elements when organizing work in multi-user information web systems. Drag and Drop is a convenient way to improve the interface. Grabbing an element with the mouse and moving it visually simplifies many operations: from copying and moving documents, as in file managers, to placing orders in online store services. The HTML drag and drop API uses the DOM event model to retrieve information about a dragged element and update that element after the drag. Using JavaScript event handlers, it is possible to turn any element of the web system into a drag-and-drop element or drop target. To solve this problem, a JavaScript object was developed with methods that allow you to create a copy of any object and handle all events of this object aimed at organizing the Drag and Drop mechanism. Basic algorithm of Drag and Drop technology based on processing mouse events. The software implementation is considered and the results of the practical use of object adaptation of the Drag and Drop technology for the interface components of the web system - the medical information system MedSystem, in which the application modules have the implementation of the dispatcher and the interactive window interface are presented. In the "Outpatient clinic" module, the Drag and Drop mechanism is used when working with the "Appointment sheet". In the "Hospital" module of the MedSystem medical information system, the Drag and Drop mechanism is used in the "List of doctor's appointments". The results of using object adaptation of Drag and Drop technology have shown that this mechanism organically fits into existing technologies for building web applications and has sufficient potential to facilitate and automate work in multi-user information systems and web services.

Abstract:
In recent years, the use of services for Open Systems development has consolidated and strengthened. Advances in the Service Science and Engineering (SSE) community, promoted by the reinforcement of Web Services and Semantic Web technologies and the presence of new Cloud computing techniques, such as the proliferation of microservices solutions, have allowed software architects to experiment and develop new ways of building open and adaptable computer systems at runtime. Home automation, intelligent buildings, robotics, graphical user interfaces are some of the social atmosphere environments suitable in which to apply certain innovative trends. This paper presents a schema for the adaptation of Dynamic Computer Systems (DCS) using interdisciplinary techniques on model-driven engineering, service engineering and soft computing. The proposal manages an orchestrated microservices schema for adapting component-based software architectural systems at runtime. This schema has been developed as a three-layer adaptive transformation process that is supported on a rule-based decision-making service implemented by means of Machine Learning (ML) algorithms. The experimental development was implemented in the Solar Energy Research Center (CIESOL) applying the proposed microservices schema for adapting home architectural atmosphere systems on Green Buildings.

Abstract:
Mobile learning is becoming increasingly popular. Educational web sites can be used as supporting learning tools for students who wish to supplement their knowledge without restrictions of time and place. The continuously increasing demand for enhanced remote and mobile services, as well as the difficulty in easily incorporating current learning services for mobile users, renders essential the adaptation of educational material for these requirements. The objective of this work is to present and evaluate a methodology for producing content semantics from learning material. The proposed approach results in recommending links, which are relevant to the mobile users’ interests, by exploiting the recorded usage of an educational portal and the semantics of the learning content. The implementation results reveal enhanced capabilities in mobile learners’ web experience and usability.

Abstract:
Web Services (WS) are fundamental software artifacts for building service oriented applications and they are usually reused by others. Therefore they must be analyzed and comprehended for maintenance tasks: identification of critical parts, bug fixing, adaptation and improvement. In this article, WSDLUD a method aimed at measuring a priori the understanding degree (UD) of WSDL (Web Service Description Language) descriptions is presented. In order to compute UD several criteria useful to measure the understanding?s complexity of WSDL descriptions must be defined. These criteria are used by LSP (Logic Scoring of Preference), a multicriteria evaluation method, for producing a Global Preference value that indicates the satisfaction level of the WSDL description regarding the evaluation focus, in this case, the understanding degree. All the criteria information required by LSP is extracted from WSDL descriptions by using static analysis techniques and processed by specific algorithms which allow gathering semantic information. This process allows to obtain a priori information about the comprehension difficulty which proves our research hypotheses that states that it is possible to compute the understanding degree of a WSDL description.

Abstract:
Adaptive control of cluster-based Web systems using neuro-fuzzy modelsA significant development of Web technologies requires the application of more and more complex systems and algorithms for maintaining high quality of Web services. Presently, not only simple decision-making tools but also complex adaptation algorithms using artificial intelligence techniques are applied for controlling HTTP request traffic. The paper presents a new LFNRD (Local Fuzzy-Neural Adaptive Request Distribution) algorithm for request distribution in cluster-based Web systems using neuro-fuzzy models of Web servers in the decision-making process. The neuro-fuzzy model which is applied is discussed in detail and a design of the Web switch using the proposed solution is presented. Finally, a testbed is described and the results of a comparative simulation study on the LFNRD algorithm, and other algorithms known from the literature and used in the industry, are presented and discussed.

Abstract:
This paper presents and discusses data on the use of technology in general and of Web 2.0 platforms and services in particular by students at the University of Milano-Bicocca. The data was obtained from a survey on media consumption habits and usage of new web technologies conducted by the university's Observatory on New Media, NuMediaBiOs. Research of this kind provides a valuable basis for the development, adaptation and improvement of existing services and offerings involving new technologies in educational contexts, given that for new technologies to be successfully integrated it is critical to have access to detailed information about how they are currently deployed by users (in this case, undergraduate students on basic degree programmes). Such analyses have implications for a range of contexts, not least for the public educational institution in which they are carried out, namely the university.

Abstract:
The next generation of climate services needs not only tailoring to specific user needs but to provide, in addition, access to key information in a usable way that satisfies the needs of different users’ profiles; especially web-based services. Here, we present the outcomes from developing such a new interactive prototype. The service provides data for robust climate analysis to underpin decision-making when planning measures to compensate for climate impact. The goal is to facilitate the communication on climate information between climate modelling communities and adaptation or mitigation initiatives from vulnerable countries that are applying for funds from the Green Climate Fund (GCF). A participatory process was ensured during four workshops in four pilot countries, with an audience of national and international experts. During this process it was made clear that in all countries there is a strong need for knowledge in climate science, while in most countries there was also an increasing need of capacity in hydrological modelling and water management. The active interaction during the workshops was found necessary to facilitate the dialogue between service developers and users. Understanding the users, transparency on potentials and limitations of climate services together with capacity development in climate science and methods were required components in the development of the service.

Improving the performance of e-learning services to provide a scalable and effective e-learning system is a big challenge for the educational organizations. The e-learning system faces many challenges in pedagogical services (e.g. learning design and learning content problems), and technical services (e.g. resource provisioning and financial cost). This article presents an e-learning environment based on cloud computing (PCLE) in attempt to enhance the e-learning services' by customizing the contents of the course's material depending on the students' knowledge, experiences, and requirements. Also, the system focuses on supporting and achieving reusability, interoperability, adaptation and personalization in order to overcome the passive role of the student and transfer it into an interactive and useful participation. On the other hand, PCLE is built over the cloud computing environment trying to overcome the traditional web-hosting challenges as scalability, availability, and cost.

Abstract:
Day after day, the number of mobile applications deployed on cloud computing continues in increasing because of smartphone capabilities improvement. Cloud computing has already succeeded in the web-based application, for that reason, the demand for context-aware services provided by cloud computing increases. To customize a cloud service that takes into account the consumer requirements, which depend on information change, it brings to light many recent challenges to cloud computing about environment-aware, location-aware, time-aware. The cloud provider, moreover, has to manage personalized applications and the constraints of mobile devices in matters of interaction abilities and communication restrictions. This paper proposes a strategy for selecting automatically an appropriate cloud environment that runs out whole requirements, defines a configuration for the associated cloud environment and able to easily adapt to the change of the environment on either the user or the cloud side or both. This process builds on the principles of dynamic software product lines, Agent-oriented software engineering, and the MAPE-k model to select and configure cloud environments according to the consumer needs and the context change.

Abstract:
Rational energy consumption in large buildings depends on both the users' consumption culture and the management systems implemented. In Colombia, few buildings have an energy management system characterized by its adaptability to the user and with a certain degree of intelligence. Thus, this document describes the summarized research process for the development of an Internet of Things (IoT) system, which has been designed to promote an intelligent lighting service in an academic environment. The IoT system orchestrates a series of sensors, monitoring systems and controlled actions, all based on the principle of making the system functions and consumption records available in real-time, via web services. The devices used are "Things" with improved functionality, becoming "Smart Things" within the IoT paradigm. Methodologically, an experimental process was followed, linking the development of electronic tools, the construction of services, and the development of interfaces for a pleasant user experience. Research contributes to two essential areas: intelligent buildings, through the intelligent adaptation of an environment; and sustainability and eco-innovation, since the system provides appropriate information for environmental education, in terms of real-time energy consumption, that impacts directly on the fair-use culture of a service expensive for the environment.

Abstract:
We investigated context-awareness by utilising multiple sources of context in a mobile device setting. In our experiment we developed a system consisting of a mobile client, running on the Android platform, integrated with a cloud-based service. These components were integrated using push messaging technology. One of the key features was the automatic adaptation of smartphones in accordance with implicit user needs. The novelty of our approach consists in the use of multiple sources of context input to the system, which included the use of calendar data and web based user configuration tool, as well as that of an external, cloud-based, configuration file storing user interface preferences which, pushed at log-on time irrespective of access device, frees the user from having to manually configure its interface. The system was evaluated via two rounds of user evaluations (n= 50 users), the feedback of which was generally positive and demonstrated the viability of using cloud-based services to provide an enhanced context-aware user experience.

Abstract:
One important aspect of ubiquitous environments is to provide users with the possibility to freely move about and continue to interact with the available applications through a variety of interactive devices such as cell phones, PDAs, desktop computers, intelligent watches, or digital television sets. Migratory applications are able to follow the user by sensing changes in the user’s context and adapting to available devices, ideally without interrupting the user experience. However, applications themselves must contain functions to monitor context information, coordinate a migration, handle application adaptation, and interact with the user during the migration process. To make life easier for developers and users of migratory applications, an integrated Migration Service Platform (MSP) is proposed, where all the common migration functions are centralised. The authors show how the platform is realised as middleware that contains a server for the central functions and lightweight client-side running on the end-user devices. The authors show how migratory applications can interact with the platform and thereby do not have to contain migration functions themselves. The authors describe the challenges following the centralisation of a migration platform that can support different types of applications, both games and business applications, implemented with either web-technologies or as component-based applications.

Abstract. Accessibility, availability, re-use and re-distribution of scientific data are prerequisites to build climate services across Europe. From this perspective the Institute of Biometeorology of the National Research Council (IBIMET-CNR), aiming at contributing to the sharing and integration of research data, has developed a research data infrastructure to support the scientific activities conducted in several national and international research projects. The proposed architecture uses open-source tools to ensure sustainability in the development and deployment of Web applications with geographic features and data analysis functionalities. The spatial data infrastructure components are organized in typical client–server architecture and interact from the data provider download data process to representation of the results to end users. The availability of structured raw data as customized information paves the way for building climate service purveyors to support adaptation, mitigation and risk management at different scales.This work is a bottom-up collaborative initiative between different IBIMET-CNR research units (e.g. geomatics and information and communication technology – ICT; agricultural sustainability; international cooperation in least developed countries – LDCs) that embrace the same approach for sharing and re-use of research data and informatics solutions based on co-design, co-development and co-evaluation among different actors to support the production and application of climate services. During the development phase of Web applications, different users (internal and external) were involved in the whole process so as to better define user needs and suggest the implementation of specific custom functionalities. Indeed, the services are addressed to researchers, academics, public institutions and agencies – practitioners who can access data and findings from recent research in the field of applied meteorology and climatology.
