Abstract
In computer based internet services, queries are usually submitted in a context. Either the contexts are created, or are assumed - e.g., a purchase order, or an airline reservation. Unfortunately, there is little theoretical foundation for contexts, and systems usually do not use them formally. In this paper, we propose a model for context representation in the direction of aspect oriented programming and object-oriented systems, and show that contexts can be used to process queries better. We outline a brief model that we are pursuing based on the idea of constraint inheritance with exceptions in a query tree.
