Datalog in Practice
Channel: Knowledge-Based Systems, TU Dresden
Date: 2021-01-06

While Datalog is not a standard like SPARQL or RDF, it can still be used for working with knowledge graphs in practice. We compare the features of Datalog (with stratified negation) and SPARQL, give a brief overview of types of modern Datalog implementations, and take a quick look at Rulewerk, the free implementation that we will use in the exercise classes.
