Where thesemodels do exist, they impose a limited interpretation of context relations in the presence of the inherentheterogeneous and dynamic characteristics of the supporting information. In this paper we introduce anapproach towards establishing context relations through the use of an improved context relational modelpermitting a wider, more complete range of application specific scenarios.
