natural language processing, actually in the browser

var nlp = require('compromise')

nlp('Wee-ooh, I look just like buddy holly.').sentences().toPastTense()
// 'Wee-ooh, I looked just like buddy holly.'

nlp('..then consider me Miles Davis!').people().out('freq')
// [{ text:'Miles Davis', count:1 }]

compromise makes working with text easy

no jargon,   |   no config,   |   no training

_{🙌 you can do it!}

Part-of-Speech tags	nouns, verbs, adjectives..	Verb conjugation	change tense of a verb or sentence
Number parsing	'seven hundred and fifty' -> 750	Named-entities	the people, places, orgs..
Template-matches	match natural-language forms	Text cleanup	contractions, hyphenation, punctuation

Client-side!

<script src="https://unpkg.com/compromise@latest/builds/compromise.min.js"></script>
<script>
  var doc = nlp('dinosaur')

  var str = doc.nouns().toPlural().out('text')
  console.log(str)
  // 'dinosaurs'
</script>

🌋 Server-side!

var nlp = require('compromise')

var doc = nlp('London is calling')
doc.sentences().toNegative()
// 'London is not calling'

Grab some words,

you can use pre-defined selections (like .nouns()) or grab any pattern with .match()

doc = nlp('Ludwig van Beethoven wrote to Josephine Brunsvik')

doc.people().out('list')
// ['ludwig van beethoven', 'josephine brunsvik']

doc.match('#TitleCase van #LastName').out()
// 'Ludwig van Beethoven'

doc.match('#PastTense to').hyphenate().out()
// 'wrote-to'

Plural/singular:

grab the noun-phrases, make em plural:

doc = nlp('a bottle of beer on the wall.')
doc.nouns().first().toPlural()
doc.out('text')
//'The bottles of beer on the wall.'

Number parsing:

parse written-out numbers, and change their form:

doc = nlp('ninety five thousand and fifty two')
doc.values().toNumber().out('text')
// '95052'

doc = nlp('the 23rd of December')
doc.values().add(2).toText()
doc.out('text')
// 'the twenty fifth of December'

Normalization:

handle the craziness:

doc = nlp("the guest-singer's björk   at seven thirty.").normalize().out('text')
// 'The guest singer is Bjork at 7:30.'

Tense:

all your base are belong:

let doc = nlp('she sells seashells by the seashore.')
doc.sentences().toFutureTense().out('text')
//'she will sell seashells...'

doc.verbs().conjugate()
// [{ PastTense: 'sold',
//    Infinitive: 'sell',
//    Gerund: 'selling', ...
// }]

Named-entities:

get the people, places, organizations:

doc = nlp('that opera about richard nixon visiting china')
doc.topics().data()
// [
//   { text: 'richard nixon' },
//   { text: 'china' }
// ]

Error correction:

make it say what you'd like:

var lexicon={
  'boston': 'MusicalGroup'
}
doc = nlp('i heard Boston\'s set in Chicago', lexicon)
doc.match('#MusicalGroup').length
// 1

//alternatively, fix it all 'in-post':
doc.match('heard #Possessive set').terms(1).tag('MusicalGroup')
doc.match('#MusicalGroup').length
// 1

Handy outputs:

get sensible data:

doc = nlp('We like Roy! We like Roy!').sentences().out('array')
// ['We like Roy!', 'We like Roy!']

doc = nlp('Tony Hawk').out('html')
/*
<span>
  <span class="nl-Person nl-FirstName">Tony</span>
  <span>&nbsp;</span>
  <span class="nl-Person nl-LastName">Hawk</span>
</span>
*/

and yes, ofcourse, there's a lot more stuff.
