• Summary :
  • New technologies such as communicating objects and the Internet of Things (IoT) have led to increasingly sophisticated systems. Supposed to provide services according to the context in which they are located and, therefore, to adapt their use of resources, these systems require increasing knowledge from their users in order to configure and use them, whereas they should not take up all the attention of the users. They need to be as "discrete" as possible, and provide the information or service only when necessary.
  • These systems, which are called "Calm technologies", give the human being a place as an end user and not as a technological expert. Various approaches are used to build such systems. We can mention multi-agent systems, adaptable systems, "self-X" systems, etc. These approaches share fundamental characteristics such as autonomy, intelligence and adaptation to their environmental context.
    The approach we propose to meet these needs is based on the concept of the Wise Object (WO). A wise object is endowed with learning capabilities about itself and its environment. The objective of the thesis is to focus on the design of such systems and in particular on the representation and manipulation of the knowledge they encompass. We will also aim at the application of wise objects to the IoT and the smart home.
  • We have already designed and implemented an object-oriented middleware (framework) (implemented in Java), called WOF (WO Framework), which allows to build wise systems, composed of WO. A WO is able to build autonomously a knowledge about the services (its skills) that it must provide and a knowledge about the uses made of these services. In the current version of the WOF, this knowledge is respectively represented by state-transition graphs and Markov statistical graphs. We have also studied several application scenarios in the context of the intelligent home and homecare for the elderly.
