Datalog+/-: A Family of Languages for Ontology Querying.

Datalog+/-: A Family of Languages for Ontology Querying.

Taispeáin leaganacha eile (1)

In ontology-based data access, an extensional database is enhanced by an ontology that generates new intensional knowledge which has to be considered when answering queries. In this setting, tractable data complexity (i.e., complexity w.r.t. the data only) of query answering is crucial, given the ne...
