Practical RDF Schema reasoning with annotated Semantic Web data

Practical RDF Schema reasoning with annotated Semantic Web data

This video was recorded at 10th International Semantic Web Conference (ISWC), Bonn 2011. Semantic Web data with annotations is becoming available, being YAGO knowledge base a prominent example. In this paper we present an approach to perform the closure of large RDF Schema annotated semantic web data using standard database technology. In particular, we exploit several alternatives to address the problem of computing transitive closure with real fuzzy semantic data extracted from YAGO in the PostgreSQL database management system. We benchmark the several alternatives and compare to classical RDF Schema reasoning, providing the first implementation of annotated RDF schema in persistent storage.
