On the efficiency of semantic web based context computing infrastructures

We present in this paper the results of testing the OCP2 middleware. OCP2 is an efficient middleware for context information management with reasoning capabilities based on semantic web, which offers different ways to express real world behavior (such as rules or patterns), modeling them on top of the ontology. More specifically, we focus on its performance and scalability. Performance has always been one of the biggest drawbacks of the semantic web, and we have work hard to change this. The results are outstanding marks using hundreds of simultaneous users.
