NAME

WordNet::Similarity::FrequencyCounter - Support functions for frequency counting programs used to estimate the information content of concepts.

METHODS

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.

returns: nothing.

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.
