Method Detail

scoreAll

java.util.List<SimilarityScore> scoreAll(java.util.List<java.lang.String> features,
                                         java.lang.String target)

Calculates all similarity scores for a given set of features.

Parameters:

features - The list of features.

target - The target string to compare against the features.

Returns:

A list of similarity scores.

score

double score(java.lang.String feature,
             java.lang.String target)

Calculates the similarity score of a single feature.

Parameters:

feature - The feature string to compare.

target - The target string to compare against the feature.

Returns:

The similarity score between the feature and target.

findTop

SimilarityScore findTop(java.util.List<java.lang.String> features,
                        java.lang.String target)

Finds the feature within a set of given features that best match the target string.

Parameters:

features - A list of strings containing the features to compare.

target - The target string to compare against the features.

Returns:

A SimilarityScore that has the highest score value amongst the features.

findTop

SimilarityScore findTop(java.util.List<java.lang.String> features,
                        java.lang.String target,
                        java.util.Comparator<SimilarityScore> comparator)

Finds the feature within a set of given features that best match the target string.

Parameters:

features - A list of strings containing the features to compare.

target - The target string to compare against the features.

comparator - A comparator that is used sort the scores.

Returns:

A SimilarityScore that has the top value amongst the features, according to the comparator.
