Ubiquitous and pervasive computing environments have the potential to provide rich sources of information about a user and their surroundings.Such context information may form a basis upon which Adaptive Information Services may be adapted.However, the nature of context information means that it is usually gathered in an ad-hoc and distributed manner with many devices and sensors storing potentially relevant data.The reconciliation and reasoning across this information presents a research challenge, but has the possibility of yielding valuable insights about users.In an ad-hoc pervasive computing environment, determining context information cannot rely on a fixed meta-data schema.This work shows how an ontology driven context service architecture will perform distributed open schema queries over heterogeneous context sources in order to provide information service adaptation.
