Collect all the SUMO terms that are found in the sentence.

polysemous

public static boolean polysemous(java.lang.String word)

polysemous

public static boolean polysemous(java.lang.String word,
                                 int pos)

collectWordSenses

public static java.util.ArrayList<java.lang.String> collectWordSenses(java.lang.String text)

Collect all the synsets that represent the best guess at meanings for all the words in a text given a larger linguistic context.

Returns:

9 digit synset IDs

findWordSenseInContext

public static java.lang.String findWordSenseInContext(java.lang.String word,
                                                      java.util.List<java.lang.String> words)

Return the best guess at the synset for the given word in the context of the sentence. @return the 9-digit synset but only if there's a reasonable amount of data, otherwise return the most frequent sense.

findWordSenseInContextWithPos

public static java.lang.String findWordSenseInContextWithPos(java.lang.String word,
                                                             java.util.List<java.lang.String> words,
                                                             int pos,
                                                             boolean lemma)

Return the best guess at the synset for the given word in the context of the sentence with the given POS.

Parameters:

word - - word to disambiguate

words - - words in context

pos - - part of speech of @word

Returns:

the 9-digit synset but only if there's a reasonable amount of data.

findWordSensePOS

public static java.util.TreeSet<AVPair> findWordSensePOS(java.lang.String word,
                                                         java.util.List<java.lang.String> words,
                                                         int POS)

Return a list of scored guesses at the synset for the given word in the context of the sentence. Returns a TreeSet consisting AVPairs of the key score reflecting the quality of the guess the given synset is the right one and a value of a 9-digit WordNet synset

getBestDefaultSUMOsense

public static java.lang.String getBestDefaultSUMOsense(java.lang.String word,
                                                       int pos)

Get the SUMO term that represents the best guess at meaning for a word. This method attempts to convert to root form.

getBestDefaultSUMO

public static java.lang.String getBestDefaultSUMO(java.lang.String word)

Get the SUMO term that represents the best guess at meaning for a word.

getBestDefaultSense

public static java.lang.String getBestDefaultSense(java.lang.String word)

Get the POS-prefixed synset that represents the best guess at meaning for a word. If there is no wordFrequency entry for the given word then it returns any sense. @return a 9 digit synset number

getBestDefaultSense

public static java.lang.String getBestDefaultSense(java.lang.String word,

Get the POS-prefixed synset that represents the best guess at meaning for a word with a given part of speech. It picks the most frequent sense for the word in the Brown Corpus.

Returns:

a 9 digit synset number

readSick

public static java.util.ArrayList<java.util.ArrayList<java.lang.String>> readSick()
