In this paper we describe the middleware that has evolved from our attempt to capture user descriptions of policies controlling devices and services from natural language. Description Logic (DL) provides a formal link between the natural language processing, the ontology and the middleware. We show that the use of a formalism such as DL opens useful avenues to detecting and resolving conflicts in policies, both in formulation and when resolving them against incoming events and requests. We finish by arguing that pervasive middleware needs to move closer to the users' abstractions to provide a service for what will be a highly dynamic environment.

Notes
Originality: Describes the use of NL to author policy rules for configuration of devices and services in the pervasive computing environment. Description logic provides the formal link between NL processing, ontology and policy engine. Rigour: major components of the middleware are described. Significance: Argues that pervasive middleware needs to move closer to the users¿ abstractions. Outlet/Citations: Workshop at major international conference. Google scholar list 1 citation.
