getClusterMap

public java.util.Map<java.lang.String,java.util.Set<Category>> getClusterMap(Category root,
                                                                             float similarity,

Returns a set of cluster of similar categories.

Parameters:

root - the root of categories to clusterize.

similarity - a float between 0 and 1 based on how similar the specified category are to one another (1 = exact match after String cleaning (lower-case, no accent, ...)

sd - the StringDistance algorithm used to compute similarity (when similarity is < 1).

Returns:

a set of cluster of similar categories.
