nkhandic 26.3.7.post1

NK-HanDic package for installing via pip.

nkhandic-py — Python wrapper for the NK-HanDic MeCab dictionary

👉 NK-HanDic (dictionary) repository: https://github.com/okikirmui/nkhandic

nkhandic is a Python helper package that makes it easy to use NK-HanDic, a MeCab dictionary for North Korean, from Python code.

⚠️ Important distinction

• NK-HanDic = the MeCab dictionary itself (linguistic resource)
• nkhandic (this package) = a Python interface / utility layer for HanDic

The dictionary is developed and published separately;
this package focuses on Python usability.

If you need for a contemporary Korean, please check HanDic (MeCab dictionary) and handic (Python wrapper).

Overview

nkhandic provides a convenient Python interface for the NK-HanDic North Korean morphological analysis dictionary.

It allows researchers and developers to perform North Korean morphological analysis from Python without manually configuring dictionary paths or MeCab options.

The package:

• Bundles a snapshot of the NK-HanDic dictionary
• Provides high-level Python APIs
• Handles Jamo-based input/output
• Supports Hanja-aware representations
• Works across Linux, macOS, and Windows environments

🚀 Quick Start (Python)

Installation

pip install nkhandic mecab-python3 jamotools

Minimal example

import nkhandic

text = "총비서동지께서 다음과 같이 말씀하시였다."

print(nkhandic.tokenize_hangul(text))
print(nkhandic.pos_tag(text))
print(nkhandic.convert_text_to_hanja_hangul(text))

Example output

[('총비서', 'NNG'), ('동지006', 'NNG'), ('께서', 'JKS'), ('다음01', 'NNG'), ('과12', 'JKB'), ('같이', 'MAG'), ('말씀', 'NNG'), ('하다02', 'XSV'), ('시', 'EP'), ('ㅆ', 'EP'), ('다06', 'EF'), ('.', 'SF')]
['총비서', '동지', '께서', '다음', '과', '같이', '말씀', '하', '시여', 'ㅆ', '다', '.']
總秘書同志께서 다음과 같이 말씀하시였다.

High-level API (Python convenience layer)

tokenize_hangul(text)

Return a list of tokens in Hangul base form(Unified Hangul Code).

• Internally uses NK-HanDic via MeCab
• Automatically restores Hangul syllables from Jamo
• Robust against unknown words

If you want to obtain tokens in surface form instead of base form, specify “surface” for the mode option.

example:

text = "말씀하시였다."

nkhandic.tokenize_hangul(text, mode="surface")
# ['말씀', '하', '시여', 'ㅆ', '다', '.']

nkhandic.tokenize_hangul(text)
# ['말씀', '하다02', '시', 'ㅆ', '다06', '.']

---

tokenize(text)

Return tokens in Jamo surface form.

• Low-level wrapper around MeCab

text = "어쩌면 그리도 위대하신가."

nkhandic.tokenize(text)
# ['어쩌면', '그리도', '위대', '하', '시', 'ᆫ가', '.']

---

pos(text) — lightweight POS

Return (surface, coarse_pos) pairs.

• Surface is returned in Jamo surface form
• POS corresponds to the first feature field

---

pos_tag(text)

Return a list of (token, POS) tuples.

• Uses HanDic base forms(Unified Hangul Code) when available
• Falls back to surface forms for unknown words
• POS tags are based on the Sejong tag set(see https://docs.komoran.kr/firststep/postypes.html)

The following is an example for comparing pos() and pos_tag().

text = "말씀하시였다."

nkhandic.pos(text)
# [('말씀', 'Noun'), ('하', 'Suffix'), ('시여', 'Prefinal'), ('ᆻ', 'Prefinal'), ('다', 'Ending'), ('.', 'Symbol')]

nkhandic.pos_tag(text)
# [('말씀', 'NNG'), ('하다02', 'XSV'), ('시', 'EP'), ('ㅆ', 'EP'), ('다06', 'EF'), ('.', 'SF')]

---

parse(text)

Return raw MeCab output string.

• Includes all feature fields
• Intended for advanced use

print(nkhandic.parse("이제 우리앞에는 5개년계획기간이 2년 남아있다."))

output:

이제	Adverb,一般,*,*,*,이제01,이제,*,*,A,MAG
우리	Noun,代名詞,*,*,*,우리03,우리,*,*,A,NP
앞	Noun,普通,*,*,*,앞,앞,*,*,A,NNG
에	Ending,助詞,処格,*,*,에04,에,*,*,*,JKB

convert_text_to_hanja_hangul(text)

Convert text into mixed Hanja + Hangul representation.

• Uses HanDic feature field (index 7)
• Preserves whitespace and punctuation
• Converts remaining Jamo into complete Hangul syllables

⚠️ Caution

It may be possible to misidentifying homonyms. e.g. 자신: 自信/自身

Platform compatibility (important update)

Recent versions of nkhandic include a more robust MeCab initialization layer to improve cross‑platform compatibility.

Earlier versions could fail on Windows or Conda environments due to platform-specific path handling issues.

Typical errors included:

[ifs] no such file or directory: /dev/null

or failures caused by Windows path escaping when dictionary paths contained spaces.

Improvements

The initialization logic now:

• Uses os.devnull instead of /dev/null
• Automatically quotes dictionary paths
• Normalizes Windows paths to forward-slash format
• Improves MeCab argument handling

These changes make the package more reliable on:

• Windows 10 / 11
• Miniconda / Anaconda environments
• Python installations where the dictionary path contains spaces

Most users do not need to change their code.

---

Low-level access (for compatibility)

import handic

print(nkhandic.DICDIR)   # path to bundled NK-HanDic snapshot
print(nkhandic.VERSION)  # NK-HanDic dictionary version

These are provided mainly for backward compatibility and inspection.

---

Typical use cases

• Using HanDic conveniently from Python
• North Korean corpus analysis and language education research
• Preprocessing North Korean text for NLP pipelines
• Exploring Hangul / Hanja correspondences in North Korean
