Method Details

Default

public static <L extends Label> Postprocessor<L> Default()

Creates the default filter to distill semantic patterns from frequent subgraphs. This processor will - filter ill-formed trees - filter trees with less than two edit classes - filter duplicates w.r.t. isomorphism - CutNonEditedSubtrees

Returns:

the default postprocessor.

postprocess

public Postprocessor.Result<L> postprocess(List<VariationDiff<L>> frequentSubgraphs)

Performs the postprocessing described by this Postprocessor object on the list of subgraphs. To that end, all filters and transformers will be applied.

Parameters:

frequentSubgraphs - A list of subgraphs to which to apply the postprocessing.

Returns:

The processed variation diffs as well as some metadata.
