  9. def computeTransitiveClosure(triples: DataSet[Triple]): DataSet[Triple]

    Computes the transitive closure on a DataSet of triples.

    Computes the transitive closure on a DataSet of triples. Note, that the assumption is that all triples do have the same predicate.

  10. def computeTransitiveClosure(triples: Set[Triple]): Set[Triple]

    Computes the transitive closure on a set of triples, i.e.

    Computes the transitive closure on a set of triples, i.e. it is computed in-memory by the driver. Note, that the assumption is that all triples do have the same predicate.

  11. def computeTransitiveClosureOpt(triples: DataSet[Triple]): DataSet[Triple]

    Computes the transitive closure on a DataSet of triples.

    Computes the transitive closure on a DataSet of triples. Note, that the assumption is that all triples do have the same predicate. This implementation uses the Flink iterate operator (see https://ci.apache.org/projects/flink/flink-docs-master/dev/batch/iterations.html")

  12. def computeTransitiveClosureOptSemiNaive(triples: DataSet[Triple], predicate: Node = null): DataSet[Triple]

    Computes the transitive closure on a DataSet of triples.

    Computes the transitive closure on a DataSet of triples. Note, that the assumption is that all triples do have the same predicate. If no predicate is given, we take any triple from the dataset and use its predicate. We highly recommend to provide the predicate in order to avoid unnecessary operations.
