Advanced tools
npm install compromise
compromise makes it simple to interpret and match text:
let doc = nlp(entireNovel)
doc.if('the #Adjective of times').text()
// "it was the blurst of times??"
if (doc.has('^simon says #Verb+')) {
return doc.match('#Verb .*').text() //'fire the lazer ..'
}
conjugate and negate verbs in any tense:
let doc = nlp('she sells seashells by the seashore.')
doc.verbs().toPastTense()
doc.text()
// 'she sold seashells by the seashore.'
transform nouns to plural and possessive forms:
let doc = nlp('the purple dinosaur')
doc.nouns().toPlural()
doc.text()
// 'the purple dinosaurs'
interpret plaintext numbers
nlp.extend(require('compromise-numbers'))
let doc = nlp('ninety five thousand and fifty two')
doc.numbers().add(2)
doc.text()
// 'ninety five thousand and fifty four'
grab subjects in a text:
nlp.extend(require('compromise-entities'))
let doc = nlp(buddyHolly)
doc.people().if('mary').json()
// [{text:'Mary Tyler Moore'}]
let doc = nlp(freshPrince)
doc.places().first().text()
// 'West Phillidelphia'
doc = nlp('the opera about richard nixon visiting china')
doc.topics().json()
// [
// { text: 'richard nixon' },
// { text: 'china' }
// ]
work with contracted and implicit words:
let doc = nlp("we're not gonna take it, no we ain't gonna take it.")
// match an implicit term
doc.has('going') // true
// transform
doc.contractions().expand()
dox.text()
// 'we are not going to take it, no we are not going to take it.'
Use it on the client-side:
<script src="https://unpkg.com/compromise"></script>
<script>
var doc = nlp('dinosaur')
var str = doc.nouns().toPlural().text()
console.log(str)
// 'dinosaurs'
</script>
or as an es-module:
import nlp from 'compromise'
var doc = nlp('London is calling')
doc.verbs().toNegative()
// 'London is not calling'
compromise is 170kb (minified):
it's pretty fast. It can run on keypress:
it works mainly by conjugating many forms of a basic word list.
The final lexicon is ~14,000 words:
you can read more about how it works, here.
set a custom interpretation of your own words:
let myWords = {
kermit: 'FirstName',
fozzie: 'FirstName',
}
let doc = nlp(muppetText, myWords)
or make more changes with a compromise-plugin.
const nlp = require('compromise')
nlp.extend((Doc, world) => {
// add new tags
world.addTags({
Character: {
isA: 'Person',
notA: 'Adjective',
},
})
// add or change words in the lexicon
world.addWords({
kermit: 'Character',
gonzo: 'Character',
})
// add methods to run after the tagger
world.postProcess(doc => {
doc.match('light the lights').tag('#Verb . #Plural')
})
// add a whole new method
Doc.prototype.kermitVoice = function() {
this.sentences().prepend('well,')
this.match('i [(am|was)]').prepend('um,')
return this
}
})
(these methods are on the nlp
object)
(all match methods use the match-syntax.)

slash-support:
We currently split slashes up as different words, like we do for hyphens. so things like this don't work:
nlp('the koala eats/shoots/leaves').has('koala leaves') //false
inter-sentence match:
By default, sentences are the top-level abstraction.
Inter-sentence, or multi-sentence matches aren't supported:
nlp("that's it. Back to Winnipeg!").has('it back')//false
nested match syntax:
the danger beauty of regex is that you can recurse indefinitely.
Our match syntax is much weaker. Things like this are not (yet) possible:
doc.match('(modern (major|minor))? general')
complex matches must be achieved with successive .match() statements.
dependency parsing: Proper sentence transformation requires understanding the syntax tree of a sentence, which we don't currently do. We should! Help wanted with this.
