ABSTRACT
ABSTRACT The Web of Objects is a new emerging concept that represents a new way of organizing physical or abstract objects-or things-delivering a high level of services that can be discovered, composed, executed, and monitored. Building an ambient assisted living (AAL) ecosystem, according to this vision, is of great interest since it consists of multiple heterogeneous objects that need to be semantically and automatically interoperable. In this chapter, a new semantic framework for monitoring AAL heterogeneous ecosystems is presented. This framework deals with context awareness and closed-world assumption (CWA) based semantic reasoning for designing management rules and ontologies. It preserves, on one hand, the structural expressiveness provided by ontologies, through compatibility with
