摘要
A knowledge base system is provided for storing and retrieving temporal knowledge in the form of RDF triples without reification. Any resource in an RDF triple (subject predicate object) is converted into a temporal resource that includes a name and a time period components. Hence, a temporal RDF triple (temporal subject temporal predicate temporal object) is formed. The knowledge base system includes three tables for storing temporal triples: A triple Table, An Entity Table, and a Predicate Table. A temporal triple is stored in Subject, Temporal Predicate, and Object columns of the Triple Table and in the Temporal Entity column of the Entity Table. In various embodiments, an object relational, a relational, or NoSQL DBMS or a native RDF triple store system can implement the knowledge base.
