PathBasedRelatedness class

Constructors

PathBasedRelatedness(Germanet germanet, WordCategory category, {int max_len = -1, int max_depth = -1, List? synset_pair = null})
These measures use the GermaNet Graph to compute the shortest Paths between two concepts. These concepts have to have the same word category. The path lengths are normalized in different ways (depending on the measure). The path lengths are computed taking only the hypernymy / hyponymy relations into account

Methods

leacock_chodorow(Synset synset1, Synset synset2, {bool normalize = false, double normalized_max = 1.0}) → double
This method implements the leackock and chodorow relatedness measure. For the path distance and depth, node count is used.
normalize(double raw_value, double normalized_max, SemRelMeasure semrel_measure) → double
Normalizes a raw value of semantic relatedness to a value between a lower bound and the given upper bound.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.

simple_path(Synset synset1, Synset synset2, {bool normalize = false, double normalized_max = 1.0}) → double
This measure computes the pathlength and normalizes it by the longest possible shortest path between any two nodes of the corresponding word category.
toString() → String
A string representation of this object.
inherited
wu_and_palmer(Synset synset1, Synset synset2, {bool normalize = false, double normalized_max = 1.0}) → double
This methods computes the semantic relatedness by taking the path length into account, normalizing by taking the depth of the LCS. If there are several possible LCS, the one with the largest depth is taken into account.

Operators

operator ==(Object other) → bool
The equality operator.
