Getting Started

The code below illustrates the steps required to pos tag a sentence:

// Load wink-pos-tagger.
var posTagger = require( 'wink-pos-tagger' );

// Create an instance of the pos tagger.
var tagger = posTagger();

// Tag the sentence using the tag sentence api.
tagger.tagSentence( 'He is trying to fish for fish in the lake.' );
// -> [ { value: 'He', tag: 'word', normal: 'he', pos: 'PRP' },
//      { value: 'is', tag: 'word', normal: 'is', pos: 'VBZ', lemma: 'be' },
//      { value: 'trying', tag: 'word', normal: 'trying', pos: 'VBG', lemma: 'try' },
//      { value: 'to', tag: 'word', normal: 'to', pos: 'TO' },
//      { value: 'fish', tag: 'word', normal: 'fish', pos: 'VB', lemma: 'fish' },
//      { value: 'for', tag: 'word', normal: 'for', pos: 'IN' },
//      { value: 'fish', tag: 'word', normal: 'fish', pos: 'NN', lemma: 'fish' },
//      { value: 'in', tag: 'word', normal: 'in', pos: 'IN' },
//      { value: 'the', tag: 'word', normal: 'the', pos: 'DT' },
//      { value: 'lake', tag: 'word', normal: 'lake', pos: 'NN', lemma: 'lake' },
//      { value: '.', tag: 'punctuation', normal: '.', pos: '.' } ]

Notice the way instances of the word "fish" have been tagged as verb and noun.
