Performance Considerations in Ontology Based Ambient Intelligence Architectures

Abstract

One limitation that still exists for the use of ontologies in pervasive and ambient intelligence environments is the performance of the reasoning task, which can slow down the use of an application and make a solution inappropriate for some scenarios. In this paper we first present the results of a user evaluation that substantiates the amount of time, that is acceptable (from the point of view of a user) as a delay resulting from the reasoning process in ontology based scenarios. Based on this results we introduce an experimental setup to test the performance of an ontology based architecture. This test shall demonstrate the performance of the state of the art technology without specific performance optimizations and provide concrete measurements for such a setup. © Springer International Publishing Switzerland 2013.
