wordpos-web
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 fileslookup()
-- all index files & data files for matched wordrand()
-- 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.
