WordNet::Similarity::FrequencyCounter - Support functions for frequency counting programs used to estimate the information content of concepts.
- createTopHash ($wn)
Creates and loads the topmost nodes hash from WordNet.
returns: $topHash, a reference to a hash containing the topmost nodes of the noun and verb hierarchies in WordNet.
- updateWordFrequency ($word, $offsetFreq, $wn [, $opt_resnik])
Updates the counts of a given word in a given offset-frequency hash. It finds the offsets of all concepts corresponding to the given word in WordNet, and increments the frequency counts of these in the hash.
- propagateFrequency ($offsetFreq, $wn, $topHash)
This function propagates the frequencies up the is-a hierarchies in WordNet, and return a hash with the new frequency counts.
returns: $newFreq, hash containing updated counts.
