public class ClusterQuadrupleJoin
extends Driver

For each RDF quadruple of the input, the cluster the subject belongs to and the cluster the object belongs to, will be set.

The raw RDF quadruples and the output of the clustering step are necessary.

The following table lists the properties necessary to set.

property name description example value
de.hpi.fgis.voidgen.hadoop.tasks.ClusterQuadrupleJoin.rdf_input_paths The list of paths to the input RDF quadruples. voidGen/input3
de.hpi.fgis.voidgen.hadoop.tasks.ClusterQuadrupleJoin.cluster_input_paths The list of paths containing the clustering output. voidGen/clustering2
de.hpi.fgis.voidgen.hadoop.tasks.ClusterQuadrupleJoin.temporary_path The path for temporary MapReduce output. voidGen/temporary
de.hpi.fgis.voidgen.hadoop.tasks.ClusterQuadrupleJoin.output_path The output path containing all input RDF quadruples which got their subject cluster and object cluster set. voidGen/joined
