Abstract
In this paper, we describe a semantic middleware which aims to provide ubiquitous computing applications with high level contextual knowledge. The proposed middleware architecture is designed around service agent entities, offering transparent and reusable services for context semantic discovery, capture and aggregation. Aggregation of contextual knowledge is modeled using services composition mechanism along with dynamic discovery of available service agents enabled through hierarchical and distributed context directories organization. We introduce also a new ontological model to describe contextual knowledge and services interfaces. The proposed middleware is applied to the design of travel organization service scenario, based on the composition of some ad hoc context services.
