ChaseGoal

Query Answering Over Knowledge Graphs Using First-Order Theories

Technique to support sound and complete query answering over knowledge graphs under Datalog rules with existential quantification and equalities. ChaseGoal outperforms by several orders of magnitude in terms of runtime and memory query answering under the commercial engine RDFox, making the difference between answering a query in a few seconds or not being able to process the query at all.
