Abstract
Knowledge graph currently has two main data models: RDF graph and property graph. The query language on RDF graph is SPARQL, while the query language on property graph is mainly Cypher. Different data models and query languages hinder the wider application of knowledge graphs. In this demonstration, we propose a unified interoperable knowledge graph database system, UniKG. (1) Based on the relational model, a unified storage scheme is utilized to efficiently store RDF graphs and property graphs, and support the query requirements of knowledge graphs. (2) Using the characteristicset-based method, the storage problem of untyped entities is addressed in UniKG. (3) UniKG realizes the interoperability of SPARQL and Cypher, and enables them to interchangeably operate on the same knowledge graph. (4) With a unified Web interface, users are allowed to query with two different languages over the same knowledge graph and visualize query results and explanations.
