Python package for automatic Korean word spacing.
R verson can be found here.
Word spacing is one of the important parts of the preprocessing of Korean text analysis. Accurate spacing greatly affects the accuracy of subsequent text analysis. PyKoSpacing
has fairly accurate automatic word spacing performance,especially good for online text originated from SNS or SMS.
For example.
"아버지가방에들어가신다." can be spaced both of below.
- "아버지가 방에 들어가신다." means "My father enters the room."
- "아버지 가방에 들어가신다." means "My father goes into the bag."
Common sense, the first is the right answer.
PyKoSpacing
is based on Deep Learning model trained from large corpus(more than 100 million NEWS articles from Chan-Yub Park).
Test Set | Accuracy |
---|---|
Sejong(colloquial style) Corpus(1M) | 97.1% |
OOOO(literary style) Corpus(3M) | 94.3% |
- Accuracy = # correctly spaced characters/# characters in the test data.
- Might be increased performance if normalize compound words.
Pre-requisite:
proper installation of python3
proper installation of pip
pip install tensorflow
pip install keras
Windows-Ubuntu case: On following error.
On error: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found
sudo apt-get install libstdc++6
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade (This takes long time.)
To install from GitHub, use
pip install git+https://github.com/haven-jeon/PyKoSpacing.git
To install with command line
- setup.py 내용에서 tensorflow 버전 조건이 있는데 이걸 빼야 실행 가능
cd PyKoSpacing/
python setup.py install
>>> from pykospacing import spacing
>>> spacing("김형호영화시장분석가는'1987'의네이버영화정보네티즌10점평에서언급된단어들을지난해12월27일부터올해1월10일까지통계프로그램R과KoNLP패키지로텍스트마이닝하여분석했다.")

Run on command line(thanks lqez).
