This is a very nice and detailed paper describing a context-aware content retrieval system "consisting of four components: knowledge transformation,
query expansion, content retrieval and user interface." The system not only depends on contextual awareness, it also draws on a relevant knowledge base used to expand queries based on ontologies and other course-specific information. See especially figure 6, about halfway through the paper, for an overview diagram of the system. PDF.
