Levi Chinese

Chinese text processing plugins for Levi.

Levi Chinese aims to facilitate Chinese support in Levi full-text search. This is under active development but I am no expert in Chinese NLP. Any comments or PRs are appreciated.

npm install levi-chinese

Levi Chinese provides text processing plugins chinese.converter() and chinese.segmenter(). Mount them under the default plugins of Levi.

var levi = require('levi')
var chinese = require('levi-chinese')

var lv = levi('db')
.use(levi.tokenizer())
.use(levi.stemmer())
.use(levi.stopword())
.use(chinese.converter()) // chinese plugin
.use(chinese.segmenter()) // chinese plugin

lv.pipeline('Lorem Ipsum is dummy text我是拖拉機學院手扶拖拉機專業的。', function (err, tokens) {
  // tokens
  ['lorem', 'ipsum', 'dummi', 'text',
    '手扶拖拉机', '拖拉机', '学院', '专业' ]
})

chinese.converter()

Convert Traditional Chinese into Simplified Chinese text tokens. Based on dictionary from Tongwen

chinese.segmenter()

Chinese words segmentation using nodejieba. This requires native bindings so it only works on Node.js.
