HanziJS is a Chinese character and NLP module for Chinese language processing for Node.js. It is primarily written to help provide a framework for Chinese language learners to explore Chinese.
At present features include:
- Character decomposition into components
- Dictionary definition lookup using CC-CEDICT
- Phonetic Regularity Computation
- Example Word Calculations
Future features planned:
- Chinese sentence segmentation
- Determine regularities and other variables between characters & their components.
Currently the data was generated by Gavin Grover http://groovy.codeplex.com/wikipage?title=cjk-decomp
npm install hanzi//Require
var hanzi = require("hanzi");
//Initiate
hanzi.start();A function that takes a Chinese character and returns an object with decomposition data. Type of decomposition is optional.
Type of decomposition levels:
- 1 - "Once" (only decomposes character once),
- 2 - "Radical" (decomposes character into its lowest radical components),
- 3 - "Graphical" (decomposes into lowest forms, will be mostly strokes and small indivisable units)
var decomposition = hanzi.decompose('爱');
console.log(decomposition);
{ character: '爱',
components1: [ 'No glyph available', '友' ],
components2: [ '爫', '冖', '𠂇', '又' ],
components3: [ '爫', '冖', '𠂇', '㇇', '㇏' ] }
//Example of forced level decomposition
var decomposition = hanzi.decompose('爱', 2);
console.log(decomposition);
{ character: '爱', components: [ '爫', '冖', '𠂇', '又' ] }A function that takes a string of characters and returns one object for all characters.
var decomposition = hanzi.decomposeMany('爱橄黃');
console.log(decomposition);
{ '爱':
{ character: '爱',
components1: [ 'No glyph available', '友' ],
components2: [ '爫', '冖', '𠂇', '又' ],
components3: [ '爫', '冖', '𠂇', '㇇', '㇏' ] },
'橄':
{ character: '橄',
components1: [ '木', '敢' ],
components2: [ '木', 'No glyph available', '耳', '⺙' ],
components3: [ '一', '丨', '八', '匚', '二', '丨', '二', '丿', '一', '乂' ] },
'黃':
{ character: '黃',
components1: [ '廿', 'No glyph available' ],
components2: [ '黃' ],
components3: [ '卄', '一', '一', '二', '丨', '凵', '八' ] } }Check if a component/character exists in the data. Returns boolean value.
console.log(hanzi.ifComponentExists('乂'));
true
console.log(hanzi.ifComponentExists('$'));
falseReturns a dictionary entry object. Script type is optional.
Script type parameters:

Search type paramaters:
- 'only' - this parameter returns only entries with the characters specfied. This is a means to find all compounds words with the characters specified.
- null - returns all occurences of the character.

The frequency categories are determined relative to the frequency distribution of the dictionarySearch data compared to the corpus.

console.log(hanzi.segment("我們都是陌生人。"));
[ '我們', '都', '是', '陌生人', '。' ]Returns all possible pinyin data for a character.
console.log(hanzi.getPinyin('的'));
[ 'de5', 'di2', 'di4' ]Returns frequency data for a character based on the Junda corpus. The data is in simplified characters, but I made the function script agnostic. So both traditional and simplified will return the same data.
console.log(hanzi.getCharacterFrequency('热'));
{ number: '530',
character: '热',
count: '31190',
percentage: '76.4970999352',
pinyin: 're4',
meaning: 'heat/to heat up/fervent/hot (of weather)/warm up' }Gets a character based on its position the frequency list. This only goes up to 9933 based on the Junda Frequency list.
console.log(hanzi.getCharacterInFrequencyListByPosition(111));
{ number: '111',
character: '机',
count: '339823',
percentage: '43.7756134862',
pinyin: 'ji1',
meaning: 'machine/opportunity/secret' }Returns an array of characters with the given component. If a component has bound forms, such as 手 and 扌, they're considered the same and returns all the characters with the component.
NB: This feature is new. Data might not be hundred percent correct and consistent.
console.log(hanzi.getCharactersWithComponent('囗'));
[ '国','因','西','回','口','四','团','图','围','困','固','园','圆','圈','囚','圃','囤','囿','囡','囫','圜','囵','囹','圄','囝','圉','圊','釦']This function takes a decomposition object created by hanzi.decompose() or a character, then returns an object that displays all possible combinations of phonetic regularity relationship of the character to all its components.
Phonetic Regularity Scale:
- 0 = No regularity
- 1 = Exact Match (with tone)
- 2 = Syllable Match (without tone)
- 3 = Similar in Initial (alliterates)
- 4 = Similar in Final (rhymes)
The object returned is organized by the possible pronunciations of the character. You may notice duplicate entries in the fields, but these are there based on the similarities between the decomposition levels. It is up to the developer to use this data or not.
console.log(hanzi.determinePhoneticRegularity('洋'));
{ yang2:
{ character: '洋',
component: [ '氵', '羊', '羊', '氵', '羊', '羊' ],
phoneticpinyin: [ 'shui3', 'Yang2', 'yang2', 'shui3', 'Yang2', 'yang2' ],
regularity: [ 0, 1, 1, 0, 1, 1 ] } }Returns a short, usually one-word, meaning of a radical.
console.log(hanzi.getRadicalMeaning('氵'));
