Rule-based context reasoning is an expressive way to define
situations, which are crucial for the implementation of many
context-aware applications. Along the scenario of the Conference
Guard application we show how this reasoning can be done both by
leveraging an efficient context management (realized by the Nexus
platform) and by a generic rule based service. We present the
architecture of the Nexus semantic service, which uses the
underlying definition of a low-level context model (the Nexus
Augmented World Model) to carry out rules given in first order
logic. We realize this service in a straight forward manner by using
state-of-the-art software components (the Jena 2 framework) and
evaluate the number of instances this approach can handle. Our first
experiences show that a pre-selection of instances is necessary if
the semantic service should work on a large-scale context model.
