VLog is designed to perform efficiently intensive rule-based computation on large Knowledge Graphs (KGs). It adapts column-store technologies to attain high efficiency in terms of memory usage and speed, enabling us to process Datalog queries with thousands of rules over databases with hundreds of millions of tuples---in a live demonstration on a laptop. Our demonstration provides in-depth insights into the workings of VLog, and presents important new features such as support for arbitrary relational DBMS." . @prefix ns9: . ns2:demo-113 ns6:hasAuthorList ns9:authorList . @prefix ns10: . ns2:demo-113 ns6:isPartOf ns10:proceedings . @prefix xsd: . ns2:demo-113 ns6:keyword "Reasoning"^^xsd:string , "Rules"^^xsd:string , "Knowledge graphs"^^xsd:string , "Datalog"^^xsd:string , "Database"^^xsd:string ; ns6:title "VLog: A Column-Oriented Datalog System for Large Knowledge Graphs" . ns10:proceedings ns6:hasPart ns2:demo-113 .
