[SOLVED] How to find whether a word is a noun or a verb using Stanford parser?

How to find whether a word is a noun or a verb using Stanford parser?

I need to find whether a word is verb or noun or it is both.

For example, the word is "search" it can be both noun and a verb but Stanford parser gives NN tag to it.

Is there any way that Stanford parser will give that "search" is both noun and verb?

My current code is as follows:

public static String Lemmatize(String word) {
    WordTag w = new WordTag(word);
    w.setTag(POSTagWord(word));
    Morphology m = new Morphology();
    WordLemmaTag wT = m.lemmatize(w);

    return wT.lemma();
}

Solution

The Stanford Parser guesses the part-of-speech tag of a word based on context statistics. You should really pass in a complete sentence to determine whether, in that sentence, "search" is a noun or a verb.

You don't need a full parser just to get part-of-speech tags. The Stanford POS Tagger is enough; it also includes the Morphology class, but it too takes context into account.

If you want all part-of-speech tags that an English word can take on, without giving context, then WordNet is probably a better choice. It has several Java interfaces, including JWNL and JWI.
