End-User-Oriented Telco Mashups: The OMELETTE Approach

With the success of Web 2.0 we are witnessing a growing number of services and APIs exposed by Telecom, IT and content providers. Targeting the Web community and, in particular, Web application developers, service providers expose capabilities of their infrastructures and applications in order to open new markets and to reach new customer groups. However, due to the complexity of the underlying technologies, the last step, i.e., the consumption and integration of the offered services, is a non-trivial and time-consuming task that is still a prerogative of expert developers. Although many approaches to lower the entry barriers for end users exist, little success has been achieved so far. In this paper, we introduce the OMELETTE project and show how it addresses end-user-oriented telco mashup development. We present the goals of the project, describe its contributions, summarize current results, and describe current and future work

The Next Big Thing: Adaptive Web-Based Systems

At the ACM Hypertext Conference a panel discussed "The Next Big Thing Inc." in the area of hypertext and hypermedia. The Web has been the "Big Thing" during the past 10 years, but its success has also made it very difficult to find the appropriate information in an ocean of over 3 billion pages. Whereas search engines achieve incredible precision, they suffer from the same "one size fits all" approach that characterizes the Web sites they index. The paper defends the position that personalization, and in particular automatic personalization or adaptation, is the key to reach the goal of offering each individual user (or user group) the information they need. During the panel discussion there was debate about whether the user should always have access and control over the entire (hypertextual) information space. There were different views on whether the "right" to all the information is best guaranteed by offering tools that reduce the information space the user perceives so that the user can actually find and reach the information, or by offering unfiltered access to an ocean of information in which everything is available but in which perhaps nothing can be found. We argue in favor of adaptation but at the same time point out flaws in the way adaptive hypermedia has been used until now. The paper then proposes a new, modular adaptive hypermedia architecture that should lead to adaptive Web-based systems as the "Next Big Thing" indeed. In this architecture, different applications can collaborate in creating and updating a user model. Shared user model servers are not just needed for adaptive Web sites, but are also the key to enabling the development of ambient intelligence. (Many small systems then need to work together and base their actions on common knowledge about their user(s).) Sharing user models can of course cause a "big brother" problem. Legislation is already in place to protect users' privacy by placing legal limits on the kind of user modeling and sharing of user models that is allowed. The paper briefly reviews the legal issues of user modeling and adaptation in order to provide not just a future outlook based on "wild imagination" but based on a realistic vision of what will not only become technically possible but also of what will be "acceptable"

Semantic web-based adaptive hypermedia

Adaptive Hypermedia constitutes a large portion of the Web nowadays. Issues of personalization and adaptation become crucial for the efficient handling of the information on the Internet. However, current hypertext reference architectures still lack appropriate modularization and expressiveness in order to meet all the challenges of Web dynamics. In the same time, standards and technologies resulting from the field of Semantic Web and Web Engineering offer flexible solutions, applicable also to the needs of Adaptive Hypermedia. In this paper we present our view on how the current development of knowledge engineering in the context of Semantic Web can contribute to the better applicability, reusability and shareability of adaptive Web-based systems. We propose a modular Semantic Web-based Adaptive Hypermedia architecture as a service-oriented framework for adaptive Web-based systems. The main goal is to help the semantic enrichment of the information search and usage process and to allow for reasoning-based adaptive support of user activities. We illustrate our ideas in the context of the CHIME project [9] for Cultural Heritage in Interactive Multimedia Environments

User modeling for modular adaptive hypermedia

More and more users work simultaneously with multiple applications, to perform various tasks. This situation puts high demands on the user adaptive systems (UAS), which traditionally support users’ work in a single isolated domain, and which now shift towards personalization in multi-task and crossapplication contexts. In their attempt to meet the increasing demands, UAS grow in complexity, but they do little about their compatibility and interoperability.We propose a Component-based Architecture for UAS: (CompAS). The key feature of CompAS is modularization of knowledge models and as a consequence allowing existing UAS to share their user models by means of a centralized user model service. As a proof of concept we show how two existing applications, AHA! [1] and UserModelService [2] can achieve interaction based on the extracted user model

Abstract CHIME: Service-oriented Framework for Adaptive Web-based Systems

In this paper we present our view on how the current development of knowledge engineering in the context of Semantic Web can contribute to the better applicability, reusability and sharability of adaptive web-based systems. We propose a service-oriented framework for adaptive web-based systems, where the main goal is to help the semantic enrichment of the information search and usage process and to allow for adaptive support of user activites. In other words, our aim is to provide flexible information access, presentation and update to a broad range of users (individual and groups) in a personalized way within the context of pursuing a user's goals and performing tasks. We take an ontological approach to enable a shared understanding of concepts throughout the system and to provide semantic relationships between the information resources and the user's knowledge of (or interest in) them. We argue that the future of adaptive web-based systems lies in the modularity of the architecture and the openess to interoperate with other applications or compontens. To achieve this we adopt the concept of the UPML framework for semantic web service integration. Our ideas are illustrated in the context of the Token2000 project for Cultural Heritage in Interactive Multimedia Environments (CHIME) and show how combining elaborate AI strategies with the simplicity of hypermedia interaction can result in more easily applicable knowledge-based systems, or in more reasoning enhanced adaptive hypermedia systems. 1

Adaptive production management using a service-based platform

This paper presents a platform for adaptive production manage-ment developed in the ARUM1 (Adaptive pRodUct Management, http://arum-project.eu/) project. The design of ARUM platform started with applying a tra-ditional enterprise Service-Oriented Architecture (SOA) paradigm to solving an integration problem for the production ramp-up of highly customized products such as aircrafts, ships, etc. The production of such articles is exceptionally challenging for planning and control, especially in small lot sizes. Often re-quests for changes at any stage of the production, immature products and pro-cesses bring serious additional risks for the producers and customers. To coun-ter such issues requires new strategies, the core elements of most of them in-clude early detection of unexpected situations followed by rapid mitigation ac-tions. Furthermore, human beings cannot cope any longer with processing a massive volume of data that comes with a high velocity from various sources that is a requirement for any modern production shop floor. The traditional IT solutions also fall short when trying to satisfy all those requirements and this motivates the need for ARUM platform to help humans in making effective decisions.info:eu-repo/semantics/publishedVersio

User Modelling for Modular Adaptive Hypermedia

Abstract. More and more users work simultaneously with multiple applications, to perform various tasks. This situation puts high demands on the user adaptive systems (UAS), which traditionally support users ’ work in a single isolated domain, and which now shift towards personalization in multi-task and crossapplication contexts. In their attempt to meet the increasing demands, UAS grow in complexity, but they do little about their compatibility and interoperability. We propose a Component-based Architecture for UAS: (CompAS). The key feature of CompAS is modularization of knowledge models and as a consequence allowing existing UAS to share their user models by means of a centralized user model service. As a proof of concept we show how two existing applications, AHA! [1] and UserModelService [2] can achieve interaction based on the extracted user model.
