On using generic profiles and views for dynamic web services adaptation

International audienceThe emergence of mobile technologies allows users to be connected to services anytime, anywhere and anyhow. However, this mobility requires new constraints on the execution of the services and their presentations to users. Hence, these ones must be selected and adapted according to not only the user's profile but also his context. In this paper, we present a new context-aware adaptation architecture based on Web Services, named CA-WIS. Our proposal aims users to interact with web services that correspond to their needs and their contexts

Dynamic Services Adaptation to the User's Context

International audienceThe diversity of terminals used by the user to access resources (Personal Digital Assistant, mobile phone, etc.) using several types of networks (wireless, local, etc.) generates a growing need to adapt services dynamically to the user's context. In this article, we present our architecture that aims at adapting content and presentation of services to the user's context. We realize the content adaptation based on a new data modeling methodology. This methodology aims to take into account the different structures associated with the same data allowing a data representation in several viewpoints. The presentation adaptation is based on an automatic generation process of the interfaces service code. The context in our architecture is presented by a generic model for the user and the service. The adaptation process is detailed based on an elearning scenario

Towards context-aware web services

International audienceThe advancement of wireless networks and mobile comuting requires advanced information systems built with contextawareness. These systems are more and more based on the usage of Web Services that are based on a system designed to support interoperable application-to-application interaction over the web. However, the classical architecture of these services does not take into account the idea of context adaptation and that is where the direction of our work is heading. In this article, we present our proposal which aims to extend the classical architecture of Web Services to a context-aware architecture in order to provide nomadic users with a list of Web Services that are adapted not only to their profile but also to their context

Towards an Adaptive Web Information System Based on Web Services

International audienceThe appearance of wireless networks and mobile computing requires building context-aware information systems. These systems are more and more based on the usage of Web Services, which are designed to support interoperable application-to-application interaction over the Web. Our aim is to build an Adaptive Web Information System based on Web services. Our contribution aims at proposing a new architecture of Web Information Systems, supporting the adaptation process to the user context and returning to the user a list of Web services adapted to his context. This architecture is based on an extension of AHA! architecture adding an adaptation layer containing various components dedicated to the context adaptation

Integrating a Context Model in Web Services

International audienceNowadays, with the great diffusion of mobile technology, and ubiquitous systems, the context has become the ear and the eye of information systems. These systems are more and more based on the usage of Web Services. The classical architecture of these Services that allows an interoperable interaction between service users and providers does not take in account context adaptation. In this article, we aim to integrate context adaptation within the classical architecture of Web Services, adding to it dedicated components that would return to nomadic users a list of Web Services that are adapted not only to his profile but also to his context

A context-aware Web Information System based on Web Services

International audienceThe increasing number of requirements for Web Information Systems and the increasing need for making their components interoperable ask for a new vision for the architecture of such Systems. We focus on two of these requirements: usability and interoperability. We present, in this paper, our contribution that aims at proposing a new architecture of Web Information Systems, supporting adaptation to the user’s context and providing the user with a list of Web Services adapted to his context. This architecture is based on an extension of AHA! architecture through an adaptation layer containing various components dedicated to the context adaptation. So, our aim is to build an Adaptive Web Information System based on Web Services. Finally, we present an algorithm to build a user contextual profile “Profile-Context-User (UCP)” containing only the user’s preferences that can be satisfied with the context

Methods of Adaptation for Web Information Systems

International audienceThe growth of information collection in this Web makes up the difficulty to the user when he/she needs access to information or service. Thus, a fundamental requirement of Web Information Systems (WIS) is now necessary. This requirement represents the ability of the system to deliver relevant information and services to the user. Consequently, the adaptation becomes a promising idea in order to increase the usability of Web Information Systems. In this paper, we present our adaptation methods. We propose relevance feedback applied in the new Web technologies using XML documents which allow the system to retrieve relevant elements according to the user’s preferences. In addition, we propose a new architecture of WIS. This architecture enables to support the adaptation process according to the user’s context and to provide the user with a list of Web Services (WS) relevant to his/her context
