Method Detail

getEuclidianSimilarityBetween

public ISimilarity getEuclidianSimilarityBetween(java.lang.Object oFirst,
                                                 java.lang.Object oSecond,
                                                 boolean bUseLevelWeighting)

Returns the similarity of the document n-gram graph oFirst as opposed to oSecond, using the inverse of the Eucledian distance. Each unique edge is supposed to correspond to a dimension and its weight is the vector value in that dimension.

Parameters:

oFirst - The first document n-gram graph.

oSecond - The second document n-gram graph.

bUseLevelWeighting - If true, uses level weighting for dimensions, based on the rank of the given edge n-grams.

Returns:

A GraphSimilarity object indicative of the similarity between the two graphs.
