Method Detail

update

public static Synonyms update(java.util.Map<java.lang.String,java.lang.String> synonymMap,
              Synonyms syn,
              java.util.HashSet<java.lang.String> stopwords)

Class for finding longest indirect synonyms for a term. For a synonym syn, get all its co-occurrences co. From all co, get the term that is not a synonym to syn. Find the longest synonym to terms and add it to the co_occurr term set of syn according to frequency E.g., "Cardinal Joseph Ratzinger" co-occurs with "Benedict_XVI" (freq a) and "pope" (freq b). Both "Benedict_XVI" and "pope" map to "Pope_Benedict_XVI" and so we add "Pope_Benedict_XVI" to "Cardinal Joseph Ratzinger"s co-occurset with frequency a+b.

Parameters:

synonymMap - - map that keeps a synonym for each term

syn - - the synonym for which we want to find indirect synonyms

Returns:

synonym syn with updated cooccur_set
