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?

code that i use now

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();
}

or should i use any other software to do it? please suggest me thanks in advance


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.

A Part-Of-Speech Tagger, A Part-Of-Speech Tagger (POS Tagger) is a piece of software that reads text in parts of speech to each word (and other token), such as noun, verb, adjective,  Noun. Number. Preposition. Pronoun. Verb. Computers make mistakes too! The core of Parts-of-speech.Info is based on the Stanford University Part-Of-Speech-Tagger.


WordNet is what you want. It provides an API to an English lexicon with possible parts-of-speech, synonyms, word senses, hypernym/hyponym relations and more.

See Yawni for a great pure-Java WordNet API.

Software > Stanford Parser, A natural language parser is a program that works out the grammatical structure of words go together (as "phrases") and which words are the subject or object of a verb. The parser outputs typed dependency parses for English and Chinese. dependencies now explicitely include a root, parser knows osprey is a noun. java -cp stanford-parser.jar edu.stanford.nlp.parser.lexparser.LexicalizedParser englishPCFG.ser.gz - For interactive use, you may find it convenient to turn off the stderr output. For example, in bash you could use the command: java -cp stanford-parser.jar edu.stanford.nlp.parser.lexparser.LexicalizedParser englishPCFG.ser.gz - 2> /dev/null


The Stanford parser parses words in the context of a sentence. To use your example of "search", in any given sentence, "search" will be a noun or a verb, but not both a noun and a verb in the same sentence.

What you're looking for is a dictionary look up. I've found several online dictionaries that would give you the information you're looking for. Here's an example from the Free Online Dictionary for the word "search".

It turns out that "search" can be a noun, verb, intransitive verb, and transitive verb.

I could not find an application programming interface (API) that would give you the same type of information as you find on the Free Online Dictionary web page. If your vocabulary list is limited, you could build your own API.

The form of the verb is determined by the head of the subject, which is directly connected to it via an nsubj edge. Other nouns that intervene between the head of the subject and the verb (here cabinet is such a noun) are irrelevant for determining the form of the verb and need to be ignored.

This post is about detecting noun phrase and verb phrase using stanford-corenlpand nltk. First lets us install stanford-corenlpand nltklibraries. We will be using stanford-corenlplibrary to detect noun and verb phrase and then extract them using nltk.
