A query method for domain ontology based on HBase

摘要

To address the problem of distributed query in the domain ontology of civil aviation emergency, this paper proposed a distributed storage and a query method of domain ontology based on HBase. It adopted a method for storing domain ontology metadata and RDF instance data separately. By researching SPARQL query and HBase interface conversion algorithm, this method gave the implementation process and effect analysis about SPARQL query preconditioning, triple query algorithm and basic graph pattern query algorithm based on HBase, which provides a method to support the semantic query for the civil aviation emergency management domain ontology in the big data platform.
