This chapter presents main issues and the state of the art of research on adaptation engineering in adaptive concept-based systems. Adaptive concept-based systems are characterised by the prominent role of concept structures, which makes content classification and conceptualisation play central roles in engineering. On top of these concept structures, adaptation is engineered in order to achieve personalisation of both the content and their presentation. For this presentation many systems use hypermedia structures, as that nicely supports the Web-based application. As a consequence, navigation adaptation is also a central issue in system design. Next to modelling domain and adaptation, it is necessary to model the user and what the system knows or assumes of the user. To discuss different approaches to these issues, we have identified three main classes of adaptive concept-based systems. Adaptive Web information systems build the more general class of data-intensive applications. We use the Hera design methodology to explain the properties of this class. The second class of systems is that of adaptive hypermedia systems. On the basis of the AHAM reference model and the AHA! system, we illustrate this class. The third class consists of adaptive task-based systems, for which we present AIMS as a representative.

The best tools to manage the exchange of information and services between heterogeneous subjects through new technological tools with particular reference to information systems are certainly the Web-based information systems. Leveraging the infrastructure of the Web, these systems may be able to handle multimedia data, to perform distributed and cooperative applications based on service, in addition to customizing applications and related data. This paper provides an overview on Web Information Systems with particular reference to GIS, presenting a description of the usage scenarios and a comparison between two significant platform for publishing spatial data.

Web information systems engineering means a collection of sound principles, methods, techniques and tools for developing Web-based information systems, which differ from traditional information systems in their unique technological platform and design philosophy. Key features of Web information systems engineering beyond traditional and object-oriented information systems development include emphasis on user navigation, the multilevel interactivity of the environment, and the advanced hypertext functionality in target information systems. A starting point for designing and modeling Web information systems is that these are essentially hypertext information systems. This chapter will specify requirements for Web information systems engineering methodologies from the viewpoints of hypermedia communication environments, adaptive hypermedia systems, and mobile hypermedia.

This chapter introduces the Web Engineering Resources Portal (WEP) as a basic reference model and guide for Web Engineers. WEP provides a general classification of Web Engineering resources under technologies, research results, and tools. It consists of a reference model and a resources portal. The objective of the WEP reference model is to provide a common basic terminology, a technical-oriented classification of Web applications (WebApps), a specification of WebApps Logical and Physical Architectures, a classification of skills needed in Web projects and a generic and adaptable Web lifecycle process model. The WEP reference model provides the framework upon which Web Engineering resources are classified and presented. The WEP portal provides several and cross-referenced taxonomies of technologies, research results, and tools whereas its objective is to facilitate Web Engineers to comprehend available resources, understand their role and appropriately use them during development and operation/maintenance of Web information systems.

In this chapter, we present the Web-based carpooling system ORISS, which was initially developed by a student project group at University of Oldenburg. It is currently being deployed at Carl von Ossietzky University of Oldenburg with support of the DBU (Federal German Foundation for the Environment). We describe the role of carpools in traffic, particularly in commuter traffic, and show perspectives of an increased usage of carpools. A significant impact on the eco-balance of the university can be expected. We explain how Internet technologies and geographic information systems can be used for the arrangement of carpools, and show advantages over traditional methods of carpooling. The concrete architecture of ORISS and the algorithms used are outlined. We conclude the chapter by describing the circumstances of deployment and propose possible future extensions of the system.

Web Information Systems

In this chapter, a conceptual modeling approach to the design of web information systems (WIS) will be outlined. The notion of media type is central to this approach. Basically, a media type is defined by a view on an underlying database schema, which allows us to transform the data content of a database into a collection of media objects that represent the data content presented at the web interface. The view is extended by operations and an adaptivity mechanism, which permits the splitting of media objects into several smaller units in order to adapt the WIS to different user preferences, technical environments and communication channels. The information entering the design of media types is extracted from a previous story boarding phase. In consecutive phases, media types have to be extended by style patterns as the next step toward implementation.

This chapter aims to study the benefits that arise from the use of virtual reality technology and World Wide Web in the field of distance education, as well as to further explore the role of instructors and learners in such a network-centric mode of education. Within this framework, special emphasis is given on the design and development of web-based virtual learning environments so as to successfully fulfil their educational objectives. In particular, the chapter includes research on distance education on the Web and the role of virtual reality, as well as study on basic pedagogical methods focusing mainly on the efficient preparation, approach and presentation of the learning content. Moreover, specific designing rules are presented considering the hypermedia, virtual and educational nature of this kind of applications. Finally, an innovative virtual reality environment for distance education in medicine, which reproduces conditions of the real learning process and enhances learning through a real-time interactive simulator, is demonstrated.

In the Web Engineering area, many methods and frameworks to support Web Information Systems (WISs) development have already been proposed. Particularly, the use of frameworks and containerbased architectures is state-of-the-practice. In this chapter, we present a method for designing framework- based WISs called FrameWeb, which defines a standard architecture for framework-based WISs and a modeling language that extends UML to build diagrams that specifically depict framework-related components. Considering that the Semantic Web has been gaining momentum in the last few years, we also propose an extension to FrameWeb, called S-FrameWeb, that aims to support the development of Semantic WISs.

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.

In this chapter, we briefly summarize the results achieved in this book, and we will provide some indications on possible future developments. In the book’s coverage, we mainly focus on the design and on the development of complex Web information systems that are information systems that aim to manage, in an explicit way, the design of the processes inside the Web application as support for them.
