Method Detail

collectSUMOFromWords

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

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

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.

findWordSendInContextWithPos

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

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

Return the best guess at the synset for the given word in the context of the sentence. Returns an ArrayList consisting of a 9-digit WordNet synset, and the score reflecting the quality of the guess the given synset is the right one.

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,

Returns:

a 9 digit synset number
