Extending Weakly-Sticky Datalog+/-: Query-Answering Tractability and Optimizations

10 Jul 2016Mostafa MilaniLeopoldo Bertossi

Weakly-sticky (WS) Datalog+/- is an expressive member of the family of Datalog+/- programs that is based on the syntactic notions of stickiness and weak-acyclicity. Query answering over the WS programs has been investigated, but there is still much work to do on the design and implementation of practical query answering (QA) algorithms and their optimizations...
