A general datalog-based framework for tractable query answering over ontologies.

A general datalog-based framework for tractable query answering over ontologies.

Taispeáin leaganacha eile (4)

In this paper, we introduce a family of expressive extensions of Datalog, called Datalog±, as a new paradigm for query answering over ontologies. The Datalog± family admits existentially quantified variables in rule heads, and has suitable restrictions to ensure highly efficient ontology querying. W...
