This paper describes the design and implementation of
Minimal
RDFS semantics based on a backward chaining approach and implemented on a clustered RDF triple store. The system presented, called
4sr
, uses 4store as base infrastructure. In order to achieve a highly scalable system we implemented the reasoning at the lowest level of the quad store, the
bind
operation. The
bind
operation runs concurrently in all the data slices allowing the reasoning to be processed in parallel among the cluster. Throughout this paper we provide detailed descriptions of the architecture, reasoning algorithms, and a scalability evaluation with the LUBM benchmark.
