Towards a Distributed Landmarks based Approach for the Localization and Discovery of Things on the Internet

With the democratization of the internet of things, the information systems are becoming pervasive. In order to improve the transparency of pervasive information systems, we suggest a process based on the use of the formal analysis of concepts for the incremental construction of landmark directories. The landmark directories permit to label and localize rapidly the object containing the services appropriate for a given request in a pervasive environment.The selection is based on landmarks which are a combination of contextual and conceptual characteristics chosen on the basis of a mathematical formalism known as Galois Lattice. Our approach is illustrated via an application of an alarm system to help detect and manage the risks in order to avoid disasters and reduce their consequences in case they occur
