wordpos-web

CDNs:

wordpos is a set of fast part-of-speech (POS) utilities for Node.js and browser using fast lookup in the WordNet database.

wordpos-web formats the WordNet DB files to allow running wordpos in the browser.

📣 Demo

Installation

 npm install wordpos-web

wordpos API Docs

See wordpos/README.

Running inside the browsers

v2.0 of wordpos introduces the capability of running in the browser. The dictionary files are optimized for fast access (lookup by lemma), but they must be fetched, parsed and loaded into browser memory. The files are loaded on-demand (unless the option preload: true is given).

The dict files can be served locally or from CDN (see samples/cdn). Include the following scripts in your index.html:

<script src="wordpos/dist/wordpos.min.js"></script>
<script>
  let wordpos = new WordPOS({
    // preload: true,
    dictPath: '/wordpos/dict',
    profile: true
  });

  wordpos.getAdverbs('this is lately a likely tricky business this is')
    .then(res => {
      console.log(res); // ["lately", "likely"]
    });
</script>

Above assumes wordpos is installed to the directory ./wordpos. ./wordpos/dict holds the index and data WordNet files generated for the web in a postinstall script.

See samples/self-hosted.

Using preload option

When running inside the browse, you can request that the necessary index & data files be preloaded, rather than loaded on demand.

Use this when you're sure the files will be used and want to minimize the on-demand wait time.

let wordpos = new WordPOS({
  preload: 'a',       // Preload adjectives index file.
  includeData: true,  // Also preload the adjectives data file.
  dictPath: '/wordpos/dict'
});

wordpos.ready().then(()=> {
  // files are loaded
});

See wordpos#options for other preload options.

A note on file sizes

The original WordNet DB is around 35 MB. The size of the "index" and "data" files formatted for the web are as follows (before any compression):

POS	data	index
adverbs	525 KB	170 KB
verbs	2.7 MB	534 KB
adjectives	3.1 MB	851 KB
nouns	15 MB🚩	4.8 MB
All (raw)	21.3 MB	6.4 MB
All (gzip)	~6 MB	1.7 MB

^🚩 Be aware this is a very large file and may take some time to fetch.

Resources fetched over CDN will be compressed. For example, the compressed noun files are 4.1 MB (data) and 1.3 MB (index). If you are self-hosting, ensure gzip compression is on for your server.

Some wordpos API need just the "index" file, while others need both. Here's the breakdown:

API	data	index
get?()	✖️	✔️
is?()	✖️	✔️
lookup?()	✔️	✔️
seek()	✔️	✔️
rand?()	✖️	✔️

The following API will access all POS files:

• getPOS() -- all index files
• lookup() -- all index files & data files for matched word
• rand() -- all index files

Dev

To run samples, npm i -g http-server, then:

$ npm run build
$ npm run start
Starting up http-server, serving ./
Available on:
  http://localhost:8080

and open your browser to that url.
