Towards Contextualized Rule Repositories for the Semantic Web

Central to the semantic web are ontologies: shared conceptualizations of domains of interest expressed in an ontology language such as OWL. Rule languages complement ontology languages. For large heterogeneous bodies of knowledge on the semantic web, contextualized knowledge repositories facilitate the organization of ontological concepts. In this paper we propose a similar mechanism – contextualized rule repositories – for organizing and executing large sets of context-specific rules. We investigate feasibility of a SPARQL Inferencing Notation (SPIN) based implementation using a real-world use case from the aeronautical domain. Furthermore, we compare SPIN-based contextualized rule repositories to a context-unaware SPIN implementation.
