Perform part-of-speech tagging of english sentences using **`wink-pos-tagger`**. It is based on transformation based learning (TBL) approach pioneered by Eric Brill.
Optimized for performance, it _pos-tags_ and _lemmatizes_ over **525,000 tokens per second** with an accuracy of **93.2%** on the standard WSJ22-24 test set. This was [benchmarked](https://github.com/bestiejs/benchmark.js) on 2.2 GHz Intel Core i7 machine with 16GB RAM using its `tagRawTokens()` API.
### Installation
Use [npm](https://www.npmjs.com/package/wink-pos-tagger) to install:
npm install wink-pos-tagger --save
### Getting Started
The code below illustrates the steps required to pos tag a sentence:
```javascript
// 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**.
