Improving Semantic Queries by Utilizing UNL Ontology and a Graph Database
Petri Kivikangas, Mitsuru Ishizuka · 2012
This paper describes an approach for improving semantic queries by utilizing Universal Words (UWs) and a graph database. Concept Description Language (CDL) is used for representing the semantic data, and Neo4j graph database is used as the storage back-end. Cypher graph query language is used as the basis for implementing the semantic queries. For improving the queries, query expansion is performed by utilizing semantic relationships between UWs, provided by UNL Ontology.
