![PyPI - Version](https://img.shields.io/pypi/v/nkhandic)

This is a package to install [NK-HanDic](https://github.com/okikirmui/nkhandic), a dictionary for morphological analysis of North Korean languages, via pip and use it in Python.

To use this package for morphological analysis, the MeCab wrapper such as [mecab-python3](https://github.com/SamuraiT/mecab-python3) is required.

**[notice]** After v.0.1.3, calendar versioning is used according to the dictionary version.

## Installation

from PyPI:

```Shell
pip install nkhandic
```

## Usage

Since NK-HanDic requires Hangul Jamo(Unicode Hangul Jamo) as input, please convert Hangul (Unicode Hangul Syllables) using modules such as [jamotools](https://pypi.org/project/jamotools/), or `tools/k2jamo.py` script included in NK-HanDic.

### basic

example:

```Python
import MeCab
import nkhandic
import jamotools

mecaboption = f'-r /dev/null -d {nkhandic.DICDIR}'

tokenizer = MeCab.Tagger(mecaboption)
tokenizer.parse('')

sentence = u'경애하는 총비서동지에 대한 절대적인 충성심을 지니고 당중앙의 구상과 결심을 철저한 실천행동으로 받들어나가야 한다.'

jamo = jamotools.split_syllables(sentence, jamo_type="JAMO")

node = tokenizer.parseToNode(jamo)
while node:
    print(node.surface, node.feature)
    node = node.next
```

### Extracting specific POS

example:

```Python
# 일반명사(pos-tag: NNG)만 추출
node = tokenizer.parseToNode(jamo)
while node:
    if node.feature.split(',')[10] in ['NNG']:
        # 사전 항목(base forms)을 출력
        print(node.feature.split(',')[5])
    node = node.next
```

result:

```Shell
경애01
총비서
동지006
절대05
충성심
당중앙001
구상08
결심01
철저
실천01
행동
```

### Tokenize

example:

```Python
mecaboption = f'-r /dev/null -d {nkhandic.DICDIR} -Otokenize'
tokenizer = MeCab.Tagger(mecaboption)

print(tokenizer.parse(jamo))
```

result:

```Shell
경애 하 는 총비서 동지 에 대하 ㄴ 절대 적 이 ㄴ 충성심 을 지니 고 당중앙 의 구상 과 결심 을 철저 하 ㄴ 실천 행동 으로 받들어 나가 야 하 ㄴ다 .
```
