Dynamic Services Adaptation to the User´s Context

The 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 e-learning scenario.
