Installation

For basic usage, just reference the main file from a CDN in an HTML script tag.

For example:

<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/keggsmurph21/notatrix/build/notatrix.js"></script>
<script>

  text = 'this is a test';
  sent = new nx.Sentence(text);
  conllu = sent.to('conllu');
  console.log(conllu.output);

</script>

Or, just clone the repository!

$ cd ~/src
$ git clone https://github.com/keggsmurph21/notatrix notatrix

Then, you can test it out directly in the browser by including a path to notatrix/build/notatrix.js in a script tag of an HTML document. All of the notatrix methods will be available on a global nx object.

For example:

<script type="text/javascript" src="file:///home/keggsmurph21/src/notatrix/build/notatrix.js"></script>
<script>

  text = 'this is a test';
  sent = new nx.Sentence(text);
  conllu = sent.to('conllu');
  console.log(conllu.output);

</script>

Alternatively, you can use this package in Node.js. To install the package and all its dependencies:

$ cd ~/src/some/existing/project
$ npm install notatrix
$ node # NOTE: this command opens the Node.js REPL

Then notatrix is available as a module via

> const nx = require('notatrix');

Basic usage

Initializing

The basic unit of notatrix is the notatrix.Sentence. Instances of this class hold format-agnostic information about sentences, and can be constructed from

• Brackets
• CG3
• CoNLL-U
• an array of field = value parameters
• a plain string
• SDParse

a string in Brackets notation

const nx = require('notatrix');
const brackets = '[root [nsubj I] have [obj [amod [advmod too] many] commitments] [advmod right now] [punct .]]';
const sent = new nx.Sentence(brackets);

a CG3 string

const nx = require('notatrix');
const cg3 = `# sent_id = mst-0001
# text = Peşreve başlamalı.
"<Peşreve>"
	"peşrev" Noun @obl #1->2
"<başlamalı>"
	"başla" Verb SpaceAfter=No @root #2->0
"<.>"
	"." Punc @punct #3->2`;
const sent = new nx.Sentence(cg3);

a CoNLL-U string

const nx = require('notatrix');
const conllu = `# sent_id = chapID01:paragID1:sentID1
# text = Кечаень сыргозтизь налкставтыця карвот .
# text[eng] = Kechai was awoken by annoying flies.
1	Кечаень	Кечай	N	N	Sem/Ant_Mal|Prop|SP|Gen|Indef	2	obj	_	Кечаень
2	сыргозтизь	сыргозтемс	V	V	TV|Ind|Prt1|ScPl3|OcSg3	0	root	_	сыргозтизь
3	налкставтыця	налкставтомс	PRC	Prc	V|TV|PrcPrsL|Sg|Nom|Indef	4	amod	_	налкставтыця
4	карвот	карво	N	N	Sem/Ani|N|Pl|Nom|Indef	2	nsubj	_	карвот
5	.	.	CLB	CLB	CLB	2	punct	_	.`;
const sent = new nx.Sentence(conllu);

a set of parameters

const nx = require('notatrix');
const params = [
  { form: 'hello' },
  { form: 'world' }
];
const sent = new nx.Sentence(params);

a plain string

const nx = require('notatrix');
const text = 'this is my test string';
const sent = new nx.Sentence(text);

an SDParse string

const nx = require('notatrix');
const sd = `He says that you like to swim
ccomp(says, like)
mark(like, that)`;
const sent = new nx.Sentence(sd);

Inspecting properties of a [notatrix.Sentence](build/docs.md#Sentence)

# text[eng] = Mona eats her food here in the kitchen.

const sent = new nx.Sentence(conllu);
console.log(sent.comments.length); // expected 3
console.log(sent.tokens.length);   // expected 8, only counts top-level tokens
console.log(sent.size);            // expected 10, counts all tokens

Some interesting properties here are notatrix.Sentence.comments, notatrix.Sentence.tokens, and notatrix.Sentence.size. For more information about the syntax of working with notatrix.Sentence objects, check out the API Documentation.

Converting to other formats

Once we have a notatrix.Sentence, we can output it to any supported format. Since not all formats will support all of the information we might want to encode, we get both an output string and a loss array that gives all of the fields we were unable to encode. To output to a specific format, we can call sent.to(format), where format is one of apertium stream (coming soon!), brackets, cg3, conllu, notatrix serial, params, plain text, or sd.

For example:

const nx = require('notatrix');
const conllu = `# this is my first comment
# here is another comment
1	hello	hello	_	_	_	0	root	_
2	,	,	PUNCT	_	_	1	punct	_	_
3	world	world	_	_	_	1	_	_`;
const sent = new nx.Sentence(conllu);

//const toApertiumStream = sent.to('apertium stream');

const toBrackets = sent.to('brackets');
/* expected:
{
  output: '[root hello [punct ,] [_ world]]',
  loss: [ 'comments', 'lemma', 'upostag' ]
}
*/

const toCG3 = sent.to('cg3');
/* expected:
{
  output: '# this is my first comment\n# here is another comment\n"<hello>"\n\t"hello" @root #1->0\n"<,>"\n\t"," PUNCT @punct #2->1\n"<world>"\n\t"world" #3->1',
  loss: []
}
*/

const toConllu = sent.to('conllu');
/* expected:
{
  output: '# this is my first comment\n# here is another comment\n1\thello\thello\t_\t_\t_\t0\troot\t_\t_\n2\t,\t,\tPUNCT\t_\t_\t1\tpunct\t_\t_\n3\tworld\tworld\t_\t_\t_\t1\t_\t_\t_',
  loss: []
}
*/

const toSerial = sent.to('notatrix serial');
/* expected: 
{
  output: { ... },
  loss: []
}
*/

const toParams = sent.to('params');
/* expected:
{
  output: [
    { form: 'hello', lemma: 'hello', head: '0' },
    { form: ',', lemma: ',', upostag: 'PUNCT', head: '1' },
    { form: 'world', lemma: 'world', head: '1' }
  ],
  loss: [ 'comments' ]
}
*/

const toPlainText = sent.to('plain text');
/* expected:
{
  output: 'hello, world',
  loss: [ 'comments', 'lemma', 'heads', 'upostag' ]
}
*/

const toSD = sent.to('sd');
/* expected:
{
  output: '# this is my first comment\n# here is another comment\nhello, world\nroot(ROOT, hello)\npunct(hello, ,)\n_(hello, world)',
  loss: [ 'lemma', 'upostag' ]
}
*/
