getting nouns and verbs from wordnet

Question

I'm struggling to find whether a word is noun or verb etc

I found the MIT Java Wordnet Interface there was a sample code like this, but when i use this i get error that Dictionary is abstract class and cannot be instantiated

public void testDictionary() throws IOException {


// construct the URL to the Wordnet dictionary directory

String wnhome = System.getenv("WNHOME");

String path = wnhome + File.separator + "dict";

URL url = new URL("file", null, path);

    // construct the dictionary object and open it

IDictionary dict = new Dictionary(url);

dict.open();


// look up first sense of the word "dog"

IIndexWord idxWord = dict.getIndexWord("dog", POS.NOUN);

IWordID wordID = idxWord.getWordIDs().get(0);

IWord word = dict.getWord(wordID);

System.out.println("Id = " + wordID);

System.out.println("Lemma = " + word.getLemma());

System.out.println("Gloss = " + word.getSynset().getGloss());

 }

i also got another java interface to wordnet

danbikel's interface

but i dont get answer for the query

WordNet wn=new WordNet("/usr/share/wordnet");
    Morphy m = new Morphy(wn);

    System.out.println(m.morphStr("search","NOUN").length);

Always the string length is 0, what is the correct arguments for this method? here is the javadoc of the method, what am i doing wrong?

public String[] morphStr(String origstr, String pos)
Tries several techniques on origstr to find possible base forms (lemmas).

Specified by:
morphStr in interface MorphyRemote
Parameters:
origstr - word or collocation, separated either by whitespace, '_' or '-', to find lemma of
pos - part of speech of origstr
Returns:
array of possible lemmas for origstr, possibly of length 0 if no lemmas could be found

Answer 1

I personally recommend Yawni, the new name for the old JWordNet project. To get all the parts-of-speech for a search word, you would call FileBackedDictionary.synsets(yourQueryWord), then iterate through the returned Synsets calling getPOS().
