Abstract

In this paper, we study the problem of keyword search over federated RDF systems. We utilize the full-text search interfaces provided by SPARQL endpoints and the authoritative documents of URIs to map keywords to the classes, and generates SPARQL queries by exploring the schema graph. Then, we send the generated queries to the SPARQL endpoints and evaluate these queries. Experiments show that our approaches are effective and efficient.
