[Corpora-List] java API to wordnet

[Tom Morton]

Dan Bikel has a nice WordNet java package as well. I believe the licencing 
is research only for that.

I'm using JWNL package within the opennlp.tools package
(opennlp.sf.net<http://opennlp.sf.net>).
It was a bit of a pain to figure out how to make the JWNL dictionary object 
without giving it a file reference to the xml file that JWNL uses to 
configure itself. The code below does this, and is configured for WordNet 
1.7 and higher. It also seems to works fine with 1.6 for features which were 
also found in that version as well. Enjoy...Tom

String searchDirectory = "/home/tsmorton/wordnet-1.6/dict"; //dict directory 
where wordnet is installed

PointerType.initialize();
Adjective.initialize();
VerbFrame.initialize();
Map suffixMap = new HashMap();
suffixMap.put(POS.NOUN,new String[][] 
{{"s",""},{"ses","s"},{"xes","x"},{"zes","z"},{"ches","ch"},{"shes","sh"},{"men","man"},{"ies","y"}});
suffixMap.put(POS.VERB,new String[][] 
{{"s",""},{"ies","y"},{"es","e"},{"es",""},{"ed","e"},{"ed",""},{"ing","e"},{"ing",""}});
suffixMap.put(POS.ADJECTIVE,new String[][] 
{{"er",""},{"est",""},{"er","e"},{"est","e"}});
DetachSuffixesOperation tokDso = new DetachSuffixesOperation(suffixMap);
tokDso.addDelegate(DetachSuffixesOperation.OPERATIONS,new Operation[] {new 
LookupIndexWordOperation(),new LookupExceptionsOperation()});
TokenizerOperation tokOp = new TokenizerOperation(new String[] {" ","-"});
tokOp.addDelegate(TokenizerOperation.TOKEN_OPERATIONS,new Operation[] {new 
LookupIndexWordOperation(),new LookupExceptionsOperation(),tokDso});
DetachSuffixesOperation morphDso = new DetachSuffixesOperation(suffixMap);
morphDso.addDelegate(DetachSuffixesOperation.OPERATIONS,new Operation[] {new 
LookupIndexWordOperation(),new LookupExceptionsOperation()});
Operation[] operations = {new LookupExceptionsOperation(), morphDso , 
tokOp};
morphy = new DefaultMorphologicalProcessor(operations);
FileManager manager = new FileManagerImpl(searchDirectory,
PrincetonRandomAccessDictionaryFile.class);
FileDictionaryElementFactory factory = new 
PrincetonWN17FileDictionaryElementFactory();
FileBackedDictionary.install(manager, morphy,factory,true);
dict = net.didion.jwnl.dictionary.Dictionary.getInstance();
morphy = dict.getMorphologicalProcessor();
}
